Koigi wa Wamwere (born December 18, 1949 in Rugongo, Nakuru District) is a Kenyan politician, human rights activist, journalist and writer. Koigi became famous for opposing both theJomo Kenyatta and Daniel arap Moi regimes, both of which sent him to detention.
Koigi’s father, Wamwere, hailed from Kiambu District. However in 1915, the British colonial government declared that all land in Kenya belong to the settlers. As a result several Kikuyu people had their land taken away. Koigi’s father (then aged 4) and his family were among the evicted and had to move to Rift Valley Province, an area traditionally inhabited by Maasai people. Koigi’s mother Wangu, escaped a forced marriage and ended up in Rift Valley, only to be forcefully married with his father. They had nine children, Koigi being the oldest. Koigi’s father worked for the colonial forest department.
Koigi was born in 1949 in Rugongo location, Bahati division, Nakuru District, Rift Valley Province. He went to Rugongo Primary School Koigi Wamwere went to Mother of Apostles seminary and later Nyeri High School. Wamwere excelled in school school and received a scholarship to Cornell University in the United States in the early 70s  and while there he got interested in politics.
Without finishing studies in Hotel Management at Cornell University, Wamwere went back to Kenya. He began lecturing at the Jogoo Commercial College and also was a freelance journalist for the now defunct newspaper Sunday Post.
He stood for the Nakuru North Constituency (now Subukia Constituency) parliamentary seat in 1974, representing KANU, the only legal political party then. The young Wamwere was defeated by seasoned Kihika Kimani, though only by 800 votes. He wrote an article critical about Jomo Kenyatta on Sunday Post newspaper and was subsequently detained in 1975 and held in prison for three years. In December 1978, after Kenyatta had died, the new president Moi released Wamwere together with Ngugi wa Thiong’o and Martin Shikuku.
He was elected to the parliament in 1979 by winning the Nakuru North Constituency, this time beating beating the outgoing MP Kihika Kimani. He teamed up with other radical and socialist politicians who were derogatory named the Seven Bearded Sisters by Charles Njonjo. Others were Abuya Abuya, James Orengo, Chelagat Mutai, Chibule wa Tsuma,Mwashengu wa Mwachofi and Lawrence Sifuna.
Wamwere was one of the several opposition figures detained by president Moi after the 1982 Kenyan coup attempt, though he maintains position of not being involved with the coup.Consequently, he lost the parliamentary seat that was won Francis Kimosop at the 1982 by-election. Kimosop committed suicide in 1986 and Wamwere, released from prison in 184, contested for the newly vacated seat in the 1986 by-election. The election was controversially won by Eric Bomett, brother-in-law of president Moi. Soon afterwards Wamwere fled toNorway fearing for his life.
In 1990 he visited Uganda, but he was kidnapped by Kenyan security officials in Kampala. He was charged with treason , and held at the Kamiti Maximum Security Prison. After being released in 1993, he again fled to Norway. He returned to Kenya in 1995, but was detained again with artificially charged with robbery with violence. He was sentenced for four years in prison and six lashes by cane. He was released on December 13, 1996 due to health issues after international condemnation and protests by activists led by Koigi’s own mother.
Having missed the 1992 elections due to detention, he prepared for the 1997 general elections by affiliating himself with the Safina party, but Safina refused to give him presidential candidature. Consequently, he stood for presidency and parliamentary seat for the minor KENDA party formed by Mukaru Ng’ang’a, but Wamwere got only 0.16% of the presidential votes  and failed to win a parliamentary seat. He went to exile once again in 1998.
At the 2002 parliamentary elections he was part of the victorious NARC coalition and he won the Subukia parliamentary seat and served as an Assistant Minister for Information in theMwai Kibaki administration. He lost the seat at the 2007 elections, now representing a little known Chama Cha Mwanachi party. He continue to write, mainly op-ed articles in the Kenyan press. He owns Sauti Ya Mwananchi, a radio station in Nakuru.
He is the author of A Woman Reborn, Justice on Trial, and I Refuse to Die, amongst other books.
