Inspired by the nationalist and
Pan-Africanist ideas of
Patrice Lumumba, the co-founder of the
Mouvement National Congolais, Gizenga helped to organize the
Parti Solidaire Africain (which was openly
left leaning). In September, President
Joseph Kasa-Vubu dismissed Lumumba and Gizenga from their positions for the former's decision to involve the
Soviet Union in the
Congo Crisis. Lumumba protested, and the government went into a deadlock over the issue. A coup launched shortly thereafter by Colonel
Joseph Mobutu politically incapacitated both Lumumba and the President, though Mobutu soon developed a working relationship with the latter. Gizenga objected to the new government and left for
Stanleyville on 13 November to form his own. On 12 December, he declared his government, the
Free Republic of the Congo, to be the legitimate ruling authority in the Congo. Lumumba had attempted to join him, but was arrested and eventually executed in the
State of Katanga in January 1961. Gizenga turned down an offer of UN protection and was eventually imprisoned on the island
Bula Mbemba which lies in the mouth of the
Congo River. In July 1964 Tshombe became prime minister and, as part of an attempted political reconciliation, ordered Gizenga's release. In spite of this, Gizenga quickly organised a Lumumbist party and denounced Tshombe's handling of the
Simba rebellion. As a result, Gizenga was placed under house arrest in September. Mobutu seized power in a
coup in November 1965, thereby freeing Gizenga. He fled to
Congo-Brazzaville, though he soon settled in
Moscow to pursue a doctorate in political science. Over the next couple of years Gizenga traveled to Egypt,
Guinea,
Mali, and
Ghana to solicit support for the fractured and crumbling anti-Mobutu movement. In 1973 he briefly joined
Laurent-Désiré Kabila's China-backed rebel group in eastern
Zaire (as The Congo was then called), thereby losing Soviet support. He then moved to
France, but was deported to
Algeria. After briefly living in
Angola, he returned to the Republic of the Congo before finally settling in
Canada. Mobutu invited him to return to Zaire in 1977 to serve as a figurehead for opposition groups, but Gizenga declined. ==Later political career==
