These clans and dynasties were later taken over by an even newer immigrant group, the Twa, possibly the Tutsi from the north, who were organized as a single clan and dominated others by force and cunning. While the Twa established themselves as an aristocracy, the older Milansi dynasty retained ritual power and the right to install the Twa chief. It was, however, the Twa (after splitting into two chiefdoms) who exercised territorial and administrative authority through their appointed officials, with orders then transmitted to elected village headmen. The Fipa had now finally become more stratified, had even more precise borders, and were governed in a more strictly supervised manner. It had become a real state.
