Historically, relations between Burundi and Rwanda have been either neighbourly or bad. From April 2015, when President Pierre Nkurunziza sought re-elected, Burundi fell into a political crisis when opponents fomented a coup. After the failure of the coup, dissidents and part of the population took refuge in Rwanda. Each side blamed the other. Diplomatic relations were broken off and economic exchanges slowed down whereas good relations had been established since 2005. A “war of airways” began. The problem is that the situation could sour relations between the people of the two countries. The aim of the article is to study the evolution of these relations since the time of monarchy.
