Johannesburg — Madagascar's history is marked by a struggle for political control. By 1700, France and England had attempted to establish settlements, while the rulers of the island's many kingdoms fought among themselves for dominance.
During the 1700s the Merina ethnic group gained control of the central plateau and established a monarchy; with British help they eventually ruled most of the island. Their reign came to an end when French marines landed on the island in the 1880s and France instituted colonial rule.
Madagascar gained independence in 1960, but since then it has been plagued by assassinations, military coups and disputed elections. Here is a timeline of the major events in the island's turbulent history.
1946 - Madagascar becomes an Overseas Territory of France.
1947 - Thousands are killed when the French put down an armed rebellion in the east.

June 1975 - Didier Ratsiraka, a military commander, becomes head of state.
December 1975 - Ratsiraka is elected president for a seven-year term in a national referendum. The country is renamed the Democratic Republic of Madagascar.

December 2001 - Ratsiraka faces Antananarivo mayor Marc Ravalomanana in the first round of the presidential election.
January 2002 - Daily protests pressure Ratsiraka's government for a recount of presidential election ballots. Madagascar's High Constitutional Court certifies that Ravalomanana got 46.2 percent of the votes and Ratsiraka got 40.8 percent - neither has the required majority of 51 percent. A runoff is set within two months but thousands of Ravalomanana's supporters take to the streets in protest. Ravalomanana calls for a national strike.
February 2002 - Ravalomanana declares himself president after two months of dispute. Ratsiraka declares martial law in the capital.
March 2002 - Ravalomanana forms a rival government and seizes the defence ministry - the last ministry controlled by Ratsiraka's government - and calls an end to the national strike. The Organization of African Unity (OAU) calls for a government of "national reconciliation" until a new ballot is held, but Ratsiraka rejects the proposal.
April 2002 - The Supreme Court annuls the disputed results of the December 2001 presidential election and after a recount hands the presidency to Ravalomanana with over 51 percent of the vote. Ratsiraka says he will not abide by the decision.

March 2009 - Soldiers in a military camp outside Antananarivo mutiny and say they will defy government orders to repress civilians. Madagascar's army chief issues a 72-hour ultimatum to the feuding political leaders to resolve their disputes or face military intervention. Ravalomanana proposes a referendum as a solution; fearing further unrest he resigns, ceding power to the military. Rajoelina assumes power with military and high court backing. The AU and the Southern African Development Community (SADC) suspend Madagascar.
