Born on February 11, 1964, Cyanzayire grew up in the Ruhango District in the Southern Province of Rwanda, as the oldest in a Christian family of eight whose parents worked as farmers.
In a speech at the National Summit of Unity and Reconciliation in 2002, she highlighted the work of church leaders visiting detainees in prison, seeking to encourage religious organizations to assist in the state-led efforts to rally support for the Gacaca court.
[12][13] Over the years, Cyanzire has also used her platform to encourage state officials and public servants to promote gender, and at the same time noted that men’s rights should also be protected saying that “[w]hat we are targeting is a totally balanced society”.
[14] In 2011, she received a Recognition Certificate by the Women Leaders Network in collaboration with the Ministry of Gender and Family Promotion, during an event in which Rwanda’s First Lady, Jeannette Kagame, gave a keynote address.
[1][15] Together with her good friend from law school at the National University of Rwanda, the Rwandan diplomat and politician, Solina Nyirahabimana, Cyanzayire played a significant role in encouraging women to join the Rwandan judiciary, particularly during her tenure as chairperson of the High Council of the Judiciary when she was in a good position to recruit women judges.
