[2] Kololo, a professor of political science,[2] was a member of the Congolese Movement for Democracy and Integral Development (MCDDI), led by Bernard Kolélas, during the early 1990s, and he participated in the February–June 1991 National Conference.
[3] Kololo remained a member of the MCDDI until splitting from it in 1994 to form a new party, the Congolese Alliance for Unity and People's Freedoms (ACULP).
[4] In the midst of the June–October 1997 civil war, he urged France to not recognize any "political leaders with armed militias" in late July 1997.
[5] During the December 1998 violence in Brazzaville, Kololo fled the city's Bacongo neighborhood and spent three months hiding in the Pool Region before arriving across the Congo River in Kinshasa;[2] he was "in a state of total exhaustion" by that point and was hospitalized in Kinshasa.
An emissary of President Denis Sassou Nguesso offered to pay for Kololo to be evacuated to Europe for urgent medical treatment, but the Belgian airline Sabena refused to accept him as a passenger on 27 April 1999 out of concern that he would die during the flight.
