Who were the ancient Thagichu people in Kenya?

West and East of the Nile. Left and Right are synonyms of West and East respectively

The Kikuyu, Meru, Kamba, Kalenjin, Ibo etc, and their connection with Godess Isis

The Kikuyu are a Bantu speaking people from Central Kenya. Though their tradition does not claim a Misri (Egypt) origin, I have demonstrated in the hubs - ‘Akhenaten and the Kikuyu’ and ‘Kikuyu people of Kenya: secrets of a migration from Egypt - that they went to great lengths to hide an origin for Egypt.

The Wikipedia states that the Kikuyu language is one of the five Thagichu languages in East Africa. It will be clear from this article that the suffix “Isu” (Ishu) is more widespread than the Wikipedia implies, with its tentacles within the Bantu and Nilotic group of languages and including the Ibo of Nigeria.

There has been a debate in a variety of media about an extinct people called the Thagichu, whom some believe were the proto-Kikuyu. According to this theory, the Thagichu in their migration separated into several groups that now form some of the communities within the Mout Kenya region. Currently, to the best of my knowledge, there is no Kikuyu division that goes by the name Thagichu. The term has acquired a negative nuance.

The term Thagichu as used by the Kikuyu has many variants in East Africa. Simon Mulongo, a Ugandan stated in a comment on Hubpages that he hails from the Bamasaaba community, also known as the Bagishu on the western and southern slopes of Mt. Elgon. I have not interrogated Simon in regard to how much Bamasaaba like the term Bagishu but I highly suspect that the community would prefer not to be known as Bagishu. This term is clearly a variant of Thagichu, also spelled as Thagicu.

Ngureco, a prolific online writer stated in another comment on Hubpages stated that “The name Thagichu is a variant of the names Thagicu (from Mavuria in Mbere, and Tharaka), Thaisu (from Kitui), Daiso (from Usambara Mountains), and Segeju ( of northeast coast of Tanzania).” Ngureco goes on to say that “The Thagicu people may have separated due to migration, disagreements, war, witchcraft...”

To advance Ngureco’s observation on the variations of the term, the following terms are synonyms of Thagichu:

Thagichu; Bagichu; Bagisu; Uasin Gishu; Athaisu; Daiso; Osu (of Nigeria)

Muthui Katana, another commentor on Hubpages suggests that the Kikuyu, Meru – chuka -Tharaka and Embu-Mbeere were one group called the THAGICU or THAICU which later separated in to different groups. This makes sense when one takes into cosideration the negative nuance to the term which may have motivated the communities going by that term to want to adopt new names. In other instances, two or more groups may have consolidated to form one large unit that was powerful enough to drop the term Thagichu (and its variants) while retaining the freedom to use it on other smaller or disadvantaged communities or clans.

The Akamba and Meru

Among the Akamba community of Eastern Kenya, those from Kitui are called by the rest Athaisu. To these Kitui people, the term Athaisu is derisive and not flattery. Like the Kikuyu who have retained the term Thagichu in mythology only, there is no Kamba section that will openly state that they are “Athaisu.” Why do the Kikuyu and Kamba people find the term Thagichu (Athaisu) unflattering?

My theory is that the term Thagichu and its variants was used by communities with a superiority complex to subjugate others who had been disadvantaged by being small in number, poor or by other causes after migration from Egypt. Initially the term was as respectful as any other.

According a scholar by the name Ferdiman, the Meru people of Mount Kenya area, then known as the Ngaa, migrated from the mythical Mbwaa in three divisions. The first division was the "Thaichu (Daiso, Thagichu, Daicho, etc.); the second division "may have been Chagala (Ki-meru: Mathagaia, Mathagala, etc.)... the earlier unity of the Ngaa gradually dissolved, and they entered an era recalled in Meru and Tharaka traditions as "the dividing" (Kagairo).” Note the use of the term “dissolve” rather than disintegrate and not “disintegration.” Note also that the Ibos have Osu, a variant of Thagichu and Nwadiala, the latter rhyming well with Mathagala.

The Maasai have a district and branch called Uasin Gishu while the Akamba of Kitui are derisively called Athaisu. Simon Mulongo has explained that the term Gishu was given to them by a Maasai Laibon after the Bamasaaba stole a bull from the Maasai. Gishu, according to Simon links them to cattle. But since the Maasai are also keepers of cattle, wouldn’t they also be Gishu? Were the Maasai saying that “now that you also seem to love cattle, you are just like us – Gishu?

The Osu Ibos of Nigeria

As can be seen from the foregoing, derivatives of the term Thagishu are common in diverse communities in East Africa. I propose that the word Osu from Nigeria is yet another derivative. The Osu caste system which has been described by Leo Igwe as “an obnoxious practice among the Igbos-in Nigeria-which has refused to go away despite the impact of Christianity, modern education and civilization, and the human rights culture.”

The Ibo, according to an ancient tradition have two classes in their society – the Nwadiala or Nwafor and the Osu. The term Nwadiala has been translated as ‘sons of the soil’ which in other words are the born-free masters. The Osu do not belong to the soil and are therefore outcasts – bondsmen who are descendants of a people who once wielded enormous privileges as servants of the W’iyi goddess or the God Amadioha.

My first encounter with this obnoxious concept was in Chinua Achebe’s No Longer At Ease where he explains how this thing called Osu came about: “Our fathers in their darkness and ignorance called an innocent man Osu, a thing given to the idols, and thereafter he became an outcast, and his children, and his children’s children forever.” The Osu are supposedly unclean since they are deemed to have been dedicated to the gods in perpetuity.

According to Leo Igwe in an online article, the Osu live separately from the Nwadiala; often close to shrines and marketplaces; they are not supposed to associate or even marry the Nwadiala. Prayers of an Osu on behalf of a Nwadiala or other community gathering are null and void and can only bring bad luck. The Osu caste system was outlawed in 1956 turning the ostracism or any form of discrimination against an Osu is a crime punishable by law. Apparently no one has ever been prosecuted in spite of persistent malpractices against the Osu everyday, even by practicing Christians, sometimes with connivance of government officials.

We have seen that the Meru people also had Thaichu and Mathagala casts before dissolving into one group. This is what the Ibo have failed to do to this day. I believe that a cast system similar to the Ibo one existed among the Kikuyu, Akamba, Meru and other communities in East Africa before they stopped the discrimination, addopted the Thagichu or otherwise metamorphosed from Thagichu by adopting fresh names.

Roots of the Osu/Thagichu in Egypt

The West (Left) and East (Right)

The River Nile was a natural border between two parts of Egypt – the West and the East. The lands in the East where the sun made its appearance were associated with life, while the lands on the West where the sun set were associated with death and the afterlife. The people living on the Eastern side had occupations associated with the living.

The Westerners - All pyramids, which are in essence royal tombs, are in the West. This is also the Left hand side when you stand facing down river. The God Osiris judged the dead from notes made by Thoth. He had married his sister Isis. The funerary priests of the West wore masks depicting Anubis the Jackal. Anubis whose other name was Kenti Amentiu was deified as a funerary God. Osiris, Isis, Anubis and the term Kenti Amentiu can be expected to survive as linguistic terms in communities that have their origins in the “West.” The tombs had a large workforce to carry out new burials, maintain the tombs and enact rituals in the chapels. These were the Westerners. I highly suspect that it was taboo for the Westerners to farm but they could keep cattle. They took a lot of pride in their profesions and kept away from farming, and eventually they came to look down upon farmers and to believe that all cattle belonged to them.

The Esterners – The Pharaoh lived in the East from where he ruled the state. This is also the right hand side when you stand facing down river. Activities related to agriculture and anything else that had nothing to do with death was on this side. The National God was determined by the Pharaoh himself as can be deduced from the prefixes of various pharaohs shown here in bold text– Amenhotep (Amun), Akhenaten (Aten), and Thothmes (Thoth). The Easterners, as part of their farming activities could keep a few cattle, but farm activities could not allow them to keep herds as large as the ones kept by Westerners.

Pastoralists and Farmers

As a rule, communities that are strictly Pastoralists are practicing a Westerner profession.

Communities that are strictly farmers are practicing an Easterner profession. Of course some communities may have been influenced to adopt any of the two economic activities from others, so it is not a fast and hard rule.

When the ancient Kikuyu were initiating warriors, they had Left hand side regiments and Right hand side regiments with slightly differing rituals. I propose that this was what had happened in Egypt where the Westerner and Esterners contributed young men to protect the state in times of war. It is likely that in different periods, the two sides did not agree, causing rifts in Egyptian Society. This was solved by a co-regency, the most notable one being Akhenaten (Easterner – right hand) and Smenkhare (Westerner – left hand). This arrangement was so remarkable that it is remembered to this day. Some communities say Kare (Smenkhare) to mean long ago, while others say Tene (Akhenaten) for long ago.

I suspect that after a migration from Ancient Egypt the society would be in three distinct classes.

  1. On the one hand there was the ruling class, nobles and their servants from the Eastern side of the Nile. These would form the upper class and owners of soil.
  2. On the other hand there were the priests and their servants on the Western side of the Nile which symbolised the setting of the sun and the afterlife. These folk would form the second class, dedicating their lives to serving Gods and assisting the living to make a smooth transition into the afterlife.
  3. The third class would be the communities that migrants found in East Africa – such as the Athi/Ndorobo of Kenya or Twa of Rwanda

Let me state from the onset that each migrating community had relatives from both sides – East and West. I suggest that the kikuyu of Nyeri were predominantly “Westerners.” the word Nyeri also implies that they were the rear guard of the Kikuyu Gathirange (pure Kikuyu) since the word shares a root with "runyiri" - tail feathers used in a dance costume. Among the Meru, the Imenti clan was predominantly “Westerners” (Note similarity with Kenti Amentiu, another name for Anubis, the funerary god). My suspicion is that these Westerners were the Thagichu.

The term Thagichu was not derogatory to begin with since in Egyptian society, people looked forward to death and an afterlife full of the same abandance that was available on earth. I would suppose that they were maintained by Chapel offerings, gifts and probably a special tax. However, upon migration, things must have turned out very different. There were no royal tombs and therefore no offerings or gifts to maintain them. It is unlikely that the Easterners could generate enouth work to sustain the Westerners in East Africa and elsewhere hence the distinct lifestyles of pastoralism (Westerners) and farming (Easterners). The association with Death and spirits of the departed is what gave a negative connotation to any term associated with the Westerners.

Where the Westerners were the majority, they looked down upon the Easterners as a poor people with no cattle.

Where the Easterners were the majority, they looked down upon the Westerners as poor people with no farm produce. Discrimination went both ways until the term “...Gishu” lost significance in East Africa.

Initially, each of the two groups prefered to marry only among themselves, thereby entrenching their differences. However, this was not always possible where one group was too small. The Kikuyu, by having two variants in their ceremonies called Kikuyu guild and Maasai guild respectively – one for the right (Kikuyu – Easterner) and one of the left (Maasai – Westerner) found a way of unifying the opposing elements, and therefore discrimination was halted.

I highly suspect that the ritual of the second birth described in another hub also served to remove a person from the minority group to the majority group for full citizenship. Eventually society forgot the original purpose of the ritual. In other words, the Westerners and the Easterners had to invent a formula to forge themselves together. The Meru, as we have seen above dissolved their two original migrant groups (Westerners and Easterners) into one cohesive tribe. Among the Ibo, a formula was never found, thereby subjugating the Osu to a life of perpetual ostracism that has persisted to this day.

The God Isis

Taking note of the fact that Nigerian Osus were dedicated to the gods, the word Isis of Ancient Egypt appears to share a root with the word Osu. From a linguistic point of view, her brother Osiris is not too far in line. It is also noteworthy that the Nandi of Kenya who would fall in the category of “Westerners” use the word “Asis” for God.

Isis, a daughter of Thoth, is depicted as a winged goddess and was one of the ‘Nine gods of On’- the ennead. Having married her brother Osiris, she was also a queen. The complete list of Gods in the ennead is as follows:

  1. Atum-Ra, 2. Shu, 3. Tefnut, 4. Geb, 5. Nut, 6. Osiris, 7. Isis, 8. Seth, 9. Nepthys.

Note that the Kikuyu have nine clans, which may be an indication that each clan was dedicated to one of the Gods in ancient times. The Ibo of Nigeria have “Nine villages of Umuofia.”

Osiris the god and RA were identified with the willow and the Sycamore tres. A picture exists in Egypt where Thothmes III “is shown being nursed at the breast of ‘his mother Isis’ in the form of a Sycamore tree.’’ Those who dedicated their work to Isis may as well have called themselves “Of Isis” with different variants as listed - Thagichu; Bagichu; Bagisu; Uasin Gishu; Athaisu; Daisu, Osu.

The earthly attendants of the “Nine Gods of On” are therefore the origins of the “the Nine villages of Umuofia in Nigeria; the Mijikenda (nine villages) of the Kenya Coast; the Nine clans of the Kikuyu and the reason why number 9 is sacred in many African communities. As can be seen in the story of Isis, the Sycamore tree (Mukuyu) was as significant to the Egyptians as it is to the Kikuyu who derive their tribal name from it.

Concluding remarks

In conclusion, the Egyptian Godess Isis and her brother Osiris are represented in the term Thagichu (and its many variants such as Daisu, Osu etc). The Migrants from Egypt were in two main classess – the Easterners (Right hand) and the Westerners (Left hand). A feeling of superiority persisted in the group that was numerically large. The larger group naturally discriminated against the smaller group. It would appear that in some cases, a Westerner community was large enough numerically to be the overlords.

Within East Africa, Thagichu and its variants remain only in myths. I interpret this to mean that the Westerners were either numerically inferior or their relince on the Easterners who were farmers increased which led them to accept adoption and integration. Their previous profession of funerary activities in Egypt also contributed to the negative nuances in the terms that they used previously and hence the need to discard them.

Hello Cyprian,

Sorry to be responding late. I am glad to hear that remnants of Thagicu still exist today. Frankly I believed that they are an extinct community. They cannot be too many though. Any idea about the size of population?

CYPRIAN THIAKUNU on January 03, 2018:

Thank for the write up about Thagichu but i am suprised of you refering to them as extinct, NO! The Thagichu are alife and well living among the Meru People of Igembe South Constituency , they speak their Language when they are alone and they speak the other Kimeru when they are with other Merus in Maua town when they are interacring with other people for Business.

they have leadership roles like M'Ethingia the Chairman on Njuri Council of elders is a Muthagichu.

i oersonally started interacting with them first in 1979 in a place where they used to live before invasion my modernity and got consumed in a place called Kanjoo. In the 1990s we managed to fundraise for one of their sons to join the university.

i being a Medical Doctor i would like to get an Anthropologist we undertake that research and try to give them support to establish their own community setup. iam sure the current Governor of Meru and Tharaka Nithi would finance such a research to mine that important Data.

in Kimeru we say "wu'u'ni for my self and they say U'u'nyee"

jamila sahar, Thanks for your encouraging comment.

Fascinating history. Many thanks for sharing

Emmanuel Kariuki (author) from Nairobi, Kenya on June 26, 2013:

Thanks ngureco for your long detailed comment.

I have learned about the Bukushu in the Okavango Delta of Botswana and I intend to read more about them. Mere coincidences are rare so I believe there is a connection with the Thagichu.

I do agree with you that the group that changes the least is despised by the others. I used to hear disparaging remarks by the Muranga Kikuyu about the Ndia so I concluded early that the Ndia were the last to arrive among the Mt. Kenya people, a fact that is implied by Ndia which is likely to have been derived from "kurigia" -to come last.

I remember reading one of your comments about communities that have "animal names" in the Mount Kenya area. I have suggested above that the Nyeri people came from the West. Note that among the Kikuyu they are the ones with animal names like Ngatia (Lion), Wangombe (of Cows) etc. I suggest you look closely at the people who claim to be Thagichu and see if they come from communities with animal names. That would support my argument about an ancient Western Origin.

You can give me the contacts of the Thagichu to follow up with later.

Thanks for the visit and believe me, I have been waiting for your comment!

ngureco on June 22, 2013:

The similarlity of the name “Bagishu” to the name “Thagichu” is an interesting angle to study more about the Thagicu people. The Bagishu people of Uganda say they originated from Uasin Gishu, Kenya. The Bagishu are very closely related to the Bukusu people of Kenya. The name Bukusu could as well have been Bukushu. And interestingly the Bukushu are Bantu people found in the Okavango Delta of Botswana.

In dialectology, there is one fact that is always constant and should as well be applicable in the study of the Thagichu people. That is:

1. Language is continuously changing all the time and when people are cut off from each other for a long period of time by either permanent geographical boundaries such as rivers, hills, or by ethnic separatism, or by political separation, the group that tends to change the least and retain the older forms of a language is the one that is most hated by the others for the negative nuance of the older forms of the original language, culture and behaviours. Of the Thagicu people, which Muthui Katana stated as Kikuyu, Meru – Chuka –Tharaka, Embu-Mbeere (and you have subconsciously omitted the Kamba), which group is the most isolated from the mainstream? That group that is the most isolated from the mainstream is the one that is the most original in the original Thagicu language.

The term Thagicu has continuously continued to acquire a negative nuance but that is naturally how it should be. In the 70s we had Thagicu traditional dancers who used to dance for the president. Today we do not hear of them. The people of Mavuria location are no doubt Thagicu but they seem to be comfortable going under the umbrella of the name Mbere, and may even use another umbrella on top of that as Embu.

If you are interested, I can provide you with contacts of people who have confided to me that they are Thagicu though you may need to do a lot of persuasion for them to agree to that as the term have already acquired negativity.

Emmanuel Kariuki (author) from Nairobi, Kenya on June 05, 2013:

A friend sent me a comment on this page through email and I thought it worthwhile to share it here with my readers:


Thanks again for this wonderful contribution.

Just one observation: the western side of the Nile, called IMENTI in the ancient language, was the RIGHT-HAND side, because they looked at directions by placing themselves say in Cairo, and then facing up-the river towards Kenya. Hence, the Left-hand side is the present-day Eastern side, and the MERU people's stories are best to illustrate this. Also, they often spoke of wars with the invaders from the East, i.e. Asia. Again, as the Meru people say, The Mugwe (mundu Mugo) used his Left-Hand to stop the invaders from the East. Now, this suggests our present-day people's negativity with the idea of being left-handed up to today.

Clearlly, facing "down the river" would mean facing the Mediterranean, since that is the lower side of the river; while facing "up the river" would be facing its source, i.e. lake Nyanza. In short, the Egyptians always looked at their geographical location vis-a-vis Nile's origin - the South ="up the river", since they acknowledged their origin as the south, the land of their ancestors as stated also by Cheik Anta Diop and also through Gikuyu language as I hope to show soon.

I think I will try to study the word 'Thagichu' more closely from a linguistic perspective, and hopefully enter the hub-page discussion. As of now, it suggests the "ancestors' world" (Tha -world, ISU -the ancients), but I will confirm.

Asante sana for your good work.
