Ikongo

Ikongo, a people of south-east Madagascar, south of and akin to the Tanalas and, like them, nominally subject to the Hovas of the province of Betsileo. But they have never been conquered, and during the wars of King Radama, in the first quarter of the present century, they successfully sustained two sieges - one of 18 the other of 12 months - in their impregnable stronghold perched on an isolated eminence in the heart of their territory. The Ikongos, though pagans, were friendly to the missionary Shaw, who visited them in 1874-75.
