The Merina people, also known as Imerina, Antimerina, Borizany or Ambaniandro and formerly called Amboalambo, are the largest ethnic group in Madagascar. They are the "highlander" Malagasy ethnic group of the African island and one of the country's eighteen official ethnic groups. Their origins are diverse, primarily from the mixing of early Austronesian settlers who arrived from Maritime Southeast Asia before the 6th century and Bantu migrants from mainland Africa that arrived centuries later, forming the early Vazimba population. Later waves of Neo-Austronesians, along with smaller groups of Arabs, Indians and Europeans, further shaped the island's ethnic composition. They speak the Merina dialect of the official Malagasy language of Madagascar, an Austronesian language.
The Merina people are now mostly found in the center of the island (in the former Antananarivo Province). Beginning in the late 18th century, Merina sovereigns expanded the political region under their control from their interior capital outwards into the island, with their King Radama I ultimately helping unite the island under their rule. The French fought two wars against the Merina people between 1883 and 1885, and again in 1895. Following their victory, they colonised Madagascar from 1895 to 1896 and abolished the Merina monarchy in 1897.
