Andriamangarira

Andriamangarira was a king from the Merina Kingdom in Madagascar. He founded the city of Antsahadinta in around 1725. He was the grandson of King Andriamasinavalona, son of Princess Ravololondrenitrimo of Ambohimiakoja, one of his daughter, with a certain Andriamifonozozoro, King of Ivatobe Ambodirano Imerinatsimo.
The tomb of Andriamangarira and his "tranomasina" (Holy house) are still visible at Antsahadinta.
After he died in 1775, his second son Andriambolamena succeeded him to the throne of Antsahadinta. Their descendants constitute the clan of Zanamangarira and their territories extend into Ankibonimerina from Miadanimerina Avaratra, Ambatomahabodo, Finaritra and Soaray; to Vakinankaratra at Isoavina, Ambatoharanana, Tsarafaritra, Antetezambato, Miadanimerina Atsimo and Ankotsaka. The whole of the territories is called "Anjanamangarira".
