Despite being the younger of King Ralambo`s two sons, Andrianjaka succeeded to the throne on the basis of his strength of character and skill as a military tactician. The most celebrated accomplishment of his reign was the capture of the hill of Analamanga from a Vazimba king. There he established the fortified compound (rova) that would form the heart of his new capital city of Antananarivo. Upon his orders, the first structures within this fortified compound (known as the Rova of Antananarivo) were constructed: several traditional royal houses were built, and plans for a series of royal tombs were designed. These buildings took on an enduring political and spiritual significance, ensuring their preservation until being destroyed by fire in 1995. Andrianjaka obtained a sizable cache of firearms and gunpowder, materials that helped to establish and preserve his dominance and expand his rule over greater Imerina.
