The Kingdom of Libolo was a pre-colonial African kingdom in what is now Angola, located on the left bank of the Cuanza river. The political methods of the Libolo differed from other ethnically Ambundu kingdoms and they may have had their roots in an older and obscure kingdom called Kulembe. Libolo kings, or hango appointed regional governors who would receive official insignia, could visit his subjects and were personally responsible for their loyalty.
