King Andriamasinavalona (1675–1710), also known as Andrianjakanavalondambo, was a King of Imerina in the central highlands of Madagascar. He made significant and enduring contributions to the social, political and economic life of Imerina. Chief among these was the expansion of his territories and the pacification and unification of certain principalities that had become locked in violent conflict; Andriamasinavalona established and ruled over the largest extent of the Kingdom of Imerina. He gave the name of Antananarivo to the capital city that was rapidly expanding around the royal palace on the hill of Analamanga, created a large public square at Andohalo outside the gates of the city, and named a series of other locations within the city. He also took possession of a distant hill he renamed Ambohimanga as a lodging for his son Andriantsimitoviaminiandriana; the royal city that developed there has been declared a UNESCO World Heritage Site.
The innovations of Andriamasinavalona were numerous and enduring. He created two additional noble castes and defined their associated rights, responsibilities and restrictions, and was responsible for introducing the tradition of the red parasol as an indicator of royalty; he also decreed that all women had the right to choose their husbands. Trade with the Sakalava kingdom enabled this king to increase the firearms, cannons and gunpowder available for the defense of the kingdom, and expanded the availability of luxury items like silver piastres and porcelain dishes. The dikes around the Betsimitatatra rice fields of Antananarivo were expanded and raised to help ensure against famine.
In the interest of strengthening the defenses of the kingdom, Andriamasinavalona divided his realm into four quadrants to be ruled by his four favorite sons. This decision had the opposite effect, however; each was interested in expanding his own realm, prompting one son to kidnap the king and hold him hostage for seven years. After the king's eventual release, he famously committed a mock human sacrifice to re-sanctify his authority. Upon his death, Andriamasinavalona's sons launched military campaigns against one another to seize each other's territories, triggering 77 years of civil war in Imerina. In Madagascar today, Andriamasinavalona's reign is remembered as a golden age of justice, harmony and prosperity.
