Within a few years, however, Jamal was assassinated by either disloyal friends or cousins around 1432 or 1433, and was succeeded by his brother Badlay ibn Sa'ad ad-Din. Sultan Badlay continued the campaigns of his younger brother and began several successful expeditions against the Christian empire. He recovered the Kingdom of Bali and began preparations of a major Adalite offensive into the Ethiopian Highlands.
