Prince Rwagasore Day is observed in Burundi every October 13, commemorating the assassination of Prince Louis Rwagasore in 1961. Rwagasore was a prominent national leader who fought for Burundi's independence from Belgian colonial rule and was the son of King Mwambutsa IV. He founded the nationalist political movement, the Union for National Progress (UPRONA), and aimed to unite the Hutu and Tutsi ethnic groups. His election victory on September 8, 1961, led to his appointment as Prime Minister, just two weeks before his assassination by Georges Kageorgis, allegedly hired by the pro-Belgian Christian Democratic Party. The day serves as a public holiday in Burundi, allowing citizens to reflect on Rwagasore's contributions to the nation's independence and unity.
