For over 60 years, almost all countries in the region have experienced some kind of political and social turmoil such as civil war, coup de tat, and genocides. In 1960, the first democratically elected Congolese prime minister was assassinated. There were unprecedented social and political havoc in a nearby “other Congo” characterized by power struggle between various political and ethnic factions in the post-independence Congo Brazzaville. In Burundi and Rwanda, ethnic tensions between the Tutsi and Hutu engulfed the developmental dreams of nationalist freedom fighters until 2015. Though arguably stable, Tanzania has experienced its own share of socio-political messy including the 1998 Mwembechai and 2001 Pemba massacres. Efforts to build a sense of sustainable peace and development based on mutual understanding and socio-political harmony has brought limited success. In all these countries, the missing link in building sustainable peace and security has been a lack of education. The chapter intends to fill this gap by critically analyzing the potential role of basic education, especially pre-primary and early grades education, in sustainable peace-building in the sub-Saharan context.
