Reaching a stable compromise on post-transition power-sharing was difficult. Although a post-transition constitution was approved in September 2004, it was approved over a boycott by the Tutsi parties. In addition, the Arusha Peace Agreement mandated that local and national elections be held before the ending of the transitional period on 31 October 2004, but transitional institutions were extended. On 28 February 2005, however, Burundians approved a post-transitional constitution by national referendum with 92.4% of the vote, with elections set to take place throughout the summer of 2005. After local, parliamentary, and other elections in June and July, on 19 August 2005, the good governance minister, Pierre Nkurunziza, became the first post-transitional president. He was elected by the National Assembly and Senate through the means of indirect presidential elections.
