 The early kingdom included Kigali but it was a small state early in its history with larger and more powerful neighbours, Bugesera and Gisaka.A member of the Gisaka dynasty killed Rwanda's king Ruganzu Bwimba in the 16th century, but Ruganzu's son Cyirima Rugwe fought back with help from Bugesera and was able to expand Rwanda's territory.In the late 16th or early 17th century, the kingdom of Rwanda was invaded from the north by the Banyoro of modern-day Uganda.
