At a young age, Andrianampoinimerina, still then known by his birth name Rambosalamarazaka, quickly emerged as the favorite to inherit the kingdom of Ambohimanga. However, the kingdom was instead inherited by his uncle Andrianjafy. Throughout his rule, the king would enact several unpopular policies. His failed wars against the king of Antananarivo led to economic strife, as did growing tribute demands from Ambohimanga's Sakalava overlords. In order to cope with these growing demands, Andrianjafy made the unpopular decision to begin manufacturing criminal accusations against his own subjects to justify selling them into slavery. This unpopular decision justified a group of nobles in overthrowing Andrianjafy and placing Andrianampoinimerina into power.
