Madagascar (/ˌmædəˈɡæskər, -kɑːr/; Malagasy: Madagasikara), officially the Republic of Madagascar (Malagasy: Repoblikan'i Madagasikara Malagasy pronunciation: [republiˈkʲan madaɡasˈkʲarə̥]; French: République de Madagascar), and previously known as the Malagasy Republic, is an island country in the Indian Ocean, approximately 400 kilometres (250 miles) off the coast of East Africa. At 592,800 square kilometres (228,900 sq mi) Madagascar is the world's 2nd largest island country. The nation comprises the island of Madagascar (the fourth- largest island in the world) and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth. The island's diverse ecosystems and unique wildlife are threatened by the encroachment of the rapidly growing human population and other environmental threats.
The archaeological evidence of the earliest human foraging on Madagascar may date up to 10,000 years ago. Human settlement of Madagascar occurred between 350 BC and 550 AD by Indianized Austronesian peoples, arriving on outrigger canoes from Indonesia). The social and religious situation of Indonesia during those times were that of Hinduism and Buddhism, along with native Indonesian culture. These were joined around the 9th 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. The Malagasy ethnic group is often divided into 18 or more subgroups, of which the largest are 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 the island was united and ruled as the Kingdom of Madagascar by a series of Merina nobles. The monarchy ended in 1897 when the island was absorbed into the French colonial empire, from which the island gained independence in 1960. The autonomous state of Madagascar has since undergone four major constitutional periods, termed republics. Since 1992, the nation has officially been governed as a constitutional democracy from its capital at Antananarivo. However, in a popular uprising in 2009, president Marc Ravalomanana was made to resign and presidential power was transferred in March 2009 to Andry Rajoelina. Constitutional governance was restored in January 2014, when Hery Rajaonarimampianina was named president following a 2013 election deemed fair and transparent by the international community.
President Andry Rajoelina was elected by direct universal suffrage in the last presidential election of 2018.
Madagascar belongs to the group of least developed countries, according to the United Nations. Malagasy and French are both official languages of the state. The majority of the population adheres to traditional beliefs, Christianity, or an amalgamation of both. Ecotourism and agriculture, paired with greater investments in education, health, and private enterprise, are key elements of Madagascar's development strategy. Under Ravalomanana, these investments produced substantial economic growth, but the benefits were not evenly spread throughout the population, producing tensions over the increasing cost of living and declining living standards among the poor and some segments of the middle class. As of 2017, the economy has been weakened by the 2009–2013 political crisis, and quality of life remains low for the majority of the Malagasy population.
