Born on June 11th, 1950, Ntidendereza’s life was marked by his dedication to public service and his contributions to the betterment of Rwanda. Tragically, he left this world four years after assuming his position in Rwanda’s Upper House of Parliament. Ntidendereza’s journey as a senator commenced on September 16th, 2019, when he was elected to represent the City of Kigali.

His election victory was a testament to his popularity, as he secured an impressive 60% of the total 110 votes cast. Competing against three other candidates, Ntidendereza emerged triumphant over John Butera, who garnered 14.5% of the votes, Zeno Mutimura (18%), and Ignace Rwakayiro Mpabukawari, who managed to secure 7.7% of the votes.

Ntidendereza held a bachelor’s degree in education and psychology, as confirmed by Senate records.

His influence extended beyond his role as a senator; he served as the Secretary General of the former National Itorero Commission from 2012 to 2018.

The term "Itorero" refers to a Rwandan civic education institution aimed at nurturing a sense of cultural identity among Rwandans. This institution imparts values such as national unity, social solidarity, patriotism, integrity, bravery, tolerance, and societal norms.

His previous positions were equally impactful. From 2009 to 2012, Ntidendereza held the position of Vice Chairman of the National Itorero Commission. Prior to that, he served as the Mayor of Kicukiro District in the City of Kigali from 2006 to 2008. Additionally, he contributed to academia as a visiting lecturer at the University of Rwanda between 1996 and 2000.

Senator William Ntidendereza has died at the age of 72.
