Madagascar's 1960 Independence and the World's Oldest Island

Madagascar became a sovereign nation on June 26, 1960, one of seventeen African countries to gain independence that year in what is remembered as Africa’s “Year of Africa.” France had ruled the island since annexing it outright in 1896, a conquest that followed decades of encroaching influence over the Merina monarchy and that provoked a brutal, French-suppressed uprising in 1947. It took until 1958 for Madagascar to become a self-governing republic within the French Community, and two more years of negotiation between local leaders and Paris before full sovereignty followed.

Philibert Tsiranana, who had already served as the territory’s prime minister, became independent Madagascar’s first president and led the country’s Social Democratic Party government until 1972. His presidency oversaw the transition from colony to nation during a period, the early 1960s, when a wave of newly independent African states was reshaping the continent’s political map.

Madagascar’s independence attracted less global attention than the size of what it had won: an island whose geological age sets it apart from every other landmass on Earth. Guinness World Records recognizes Madagascar as the world’s oldest island, dating its formation to between 80 and 100 million years ago, when it broke away from the Indian subcontinent during the later breakup of the ancient supercontinent Gondwana. It had already separated from mainland Africa tens of millions of years earlier still. At 587,041 square kilometers, it also ranks as the fourth-largest island on the planet.

That geological isolation, sustained for tens of millions of years, produced one of the most distinctive concentrations of unique wildlife anywhere on Earth. According to the Critical Ecosystem Partnership Fund, a conservation initiative backed by organizations including the World Bank and Conservation International, around 90% of the more than 11,200 known vascular plant species found across the Madagascar and Indian Ocean Islands biodiversity hotspot exist nowhere else in the world, with scientists estimating that at least 2,500 additional plant species remain undescribed. Land mammal endemism runs even higher: of 211 native land mammal species in the hotspot, 95% are found only there, a group dominated by lemurs, the primates found exclusively on Madagascar and a handful of neighboring islands. Reptile endemism reaches 96% across 457 recorded species, and amphibians are close to total: of 309 identified species in the hotspot, only one exists anywhere else on Earth.

Madagascar remains one of the world’s poorest countries by income even as its unique ecology draws global conservation attention, a gap that has shaped its politics in the decades since Tsiranana’s presidency, through a Marxist period in the 1970s and ’80s, repeated political crises, and a return to multiparty elections that continues to define the country today.
