Input: Among the ethnic groups that predominate on the coast of this country are the Tsimihety and the Sakalava as well as one that claims descent from the pirate Ratsimilaho, the Betsimisaraka. A groundbreaking study by Otto Dahl concluded that the dominant language in this country shares much of its vocabulary with the Maanjan language of the Barito River Valley. This country's central highlands include tribal groups descended from East Africans as well as culturally dominant groups such as the Betsileo and the Merina, the latter of which controlled a namesake kingdom that was ended by the French in the Franco-Hova War. One member of the Merina ethnic group, Marc Ravalomanana, was deposed in a March 2009 political crisis. This country also saw ethnic controversy throughout the 1970s as coastal elites tried to replace the French language with the Austronesian language Malagasy. FTP, identify this country located on the fourth-largest island in the world.
