Madagascar, officially the Republic of Madagascar, is an island country comprising the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's fourth largest island, the second-largest island country and the 44th largest country in the world. Its capital and largest city is Antananarivo.
Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic, around 180 million years ago, and split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation; consequently, it is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of wildlife being endemic. The island has a subtropical to tropical maritime climate. Madagascar was first settled during or before the mid-first millennium AD by Austronesian peoples, presumably arriving on outrigger canoes from present-day Indonesia. These were joined around the ninth century AD by Bantu migrants crossing the Mozambique Channel from East Africa. Other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. Consequently, there are 18 or more classified peoples of Madagascar, the most numerous being the Merina of the central highlands.
Until the late 18th century, the island of Madagascar was ruled by a fragmented assortment of shifting sociopolitical alliances. Beginning in the early 19th century, most of it was united and ruled as the Kingdom of Madagascar by a series of Merina nobles. The monarchy was ended in 1897 by the annexation by France, from which Madagascar gained independence in 1960. The country has since undergone four major constitutional periods, termed republics, and has been governed as a constitutional democracy since 1992. Following a political crisis and military coup in 2009, Madagascar underwent a protracted transition towards its fourth and current republic, with constitutional governance being restored in January 2014.
