In May 1889 Mwanga, aided by the trader Charles Stokes, approached Buganda by water, and after several bloody battles captured the capital, but shortly afterwards was again defeated, and Kalema and the Ba-Islamu reoccupied Mengo (the native capital).
Kalema died later in the same year - r890 - and was succeeded by Mbogo, a half brother of King Mutesa.
Kiwewa, refusing to submit to circumcision, was (after reigning three or four months) expelled by the B a-Islamu, who placed another brother, Kalema, on the throne and began a fanatical propaganda, forcing the peasantry to, submit to the hated circumcision.
