Andrianjaka
Andrianjaka reigned over the Kingdom of Imerina in the central highlands region of Madagascar from around 1612 to 1630.
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.
Many of the cultural practices that were to define Merina social and political life for centuries are credited to Andrianjaka.
He designated the twelve sacred hills of Imerina that were to become the spiritual and political heartland of the Merina empire, contributing to the establishment of the kingdom's traditional boundaries; clans were assigned to specific regions within his kingdom, further defining the cultural landscape.
He consolidated power through such measures as appropriating the folk tradition of "sampy" (community talismans), thereby ensuring all the powers traditionally attributed to these idols were under the control of the sovereign alone.
Merina traditions related to the burial and mourning of sovereigns are also traced back to Andrianjaka's reign.
