The name Kigali comes from the Kinyarwanda prefix ki- combined with the adjective suffix -gali, which means wide or broad. This was originally applied to Mount Kigali, most likely because the mountain itself was broad and wide, with the city later being named after the mountain. According to Rwandan oral history, the name originated in the 14th century. Rwandan scholar Alexis Kagame, who did extensive research into the country's oral history and traditions, wrote that the name Kigali came into use after King Cyilima I Rugwe completed a conquest of the area. The legend states that Rugwe viewed the territory from the top of a hill and said ''burya iki gihugu ni kigali'', which translates to "this country is vast".
