 By claiming spiritual authority through Nyabinghi, Muhumusa was able to rally the Abakiga people of northern Rwanda behind her to challenge to Musinga's claim to the throne.Over the next few years, she raised armies and organised a series of insurrections aimed at enthroning her son, Biregeya, who she claimed was Rwabugiri's legitimate successor.She also encouraged her followers to pay tribute to her, rather than Musinga's court.
