At the age of 20, Qojahmetov became a nationalist and believed that Kazakhstan is better off as an independent country. Throughout the 1970s, he lived and worked in Esik, wrote poems and articles criticizing the Soviet Union. In the autumn of 1975 and in April 1977, Qojahmetov produced anti-government leaflets. He came to Alma-Ata to distribute 670 articles and leaflets to expose the discriminatory policies of the Soviet Union and the CPSU to the students of the Veterinary Institute. As a result, he was imprisoned for two years in prison.
After being released from prison in 1979, Qojahmetov composed music and worked as a director and a teacher at various musical colleges where he gained prominence.
He participated in the Jeltoqsan riot that took place in December 1986. Qojahmetov was convicted and sent to prison where he was forced to do physical labor. However, he was later released on 7 March 1989. After the event, Qojahmetov worked as a TV music editor.[1] In 1991, he became the leader of the Jeltoqsan National Democratic Party.
From September 1991, Qojahmetov organized protests in Alma-Ata to release protesters who were involved in Jeltoqsan, allow direct presidential elections, and for Kazakhstan to declare its independence from the Soviet Union by 16 December, the 5th anniversary of Jeltoqsan riot. After the Supreme Council of the Kazakh SSR announced elections on 16 October 1991, Qojahmetov sought to be a candidate. However, the deadline for collecting signatures was shortened and Qojahmetov claimed that his signature collection was confiscated by the police.[2]
In early 1992, Qojahmetov led protests across Kazakhstan.[3] In 1994, he became the leader of the Azat Civil Movement of Kazakhstan. In 1995, Nazarbayev proposed extending his term and changing the constitution. Qojahmetov led a hunger strike near the parliament building however by then, he had little support.[4]
