King Andrianampoinimerina

Andrianampoinimerina () (c. 1745–1810) ruled the Kingdom of Imerina on Madagascar from 1787 until his death. His reign was marked by the reunification of Imerina following 77 years of civil war, and the subsequent expansion of his kingdom into neighboring territories, thereby initiating the unification of Madagascar under Merina rule. Andrianampoinimerina is a cultural hero and holds near mythic status among the Merina people, and is considered one of the greatest military and political leaders in the history of Madagascar.

Andrianampoinimerina (whose name means "the king in the heart of Imerina") took power upon deposing his uncle, King Andrianjafy, who had ruled over Imerina Avaradrano (Northern Imerina). Prior to Andrianampoinimerina's reign, Imerina Avaradrano had been locked in conflict with the three other neighboring provinces of the former kingdom of Imerina that had last been unified under King Andriamasinavalona a century before. Andrianampoinimerina established his capital at the fortified town of Ambohimanga, a site of great spiritual, cultural and political significance that was designated a UNESCO World Heritage Site in 2001. The king's original royal lodgings can still be visited at Ambohimanga today. From this position, he progressively extended his domain first over all Imerina and then over the greater Highlands, absorbing the Betsileo, Sihanaka, Bezanozano and Bara territories. Having reigned for 23 years at the time of his death, Andrianampoinimerina had successfully reunited Imerina and vastly expanded the Merina kingdom, with the intent to ultimately unify all of Madagascar under Merina rule. His son and heir, Radama I, continued the conquests Andrianampoinimerina had begun, and over the next two decades largely achieved his father's vision.
