Chagos was first discovered by the Maldivan Sultanates to the north, where sailors would come adrift on the tropical shores of the Great Chagos Bank, naming the land Folhavahi. In the great Age of Exploration, Portuguese seafarers named the archipelago Bassas de Chagas, a name referring to the Holy Wounds of Jesus's Crucifixion. However, the islands were economically unprofitable compared to the richer islands to the north and east, and so it remained bare for years to come. In 1771, the French Empire laid a claim to the islands, establishing cocunut oil plantations. This attracted the attention of the British, who claimed the islands in 1786, eventually taking control of them afer Napoleon's defeat in 1814. The islands remained a subject of the British Empire for well over a hundred years, absorbed into the administrative territory of Mauritius. Descendents of slaves who had worked the coconut plantations inhabited the islands peacefully, living Spartan lives on the beaches and jungles. However, in 1965 with Mauritius being granted self-government, the UK purchased the archipelago with the intent to remove the plantations, installing a United States Military Base. Between 1967 and 1973, the entire population of Chagos was forcibly moved to either the Seychells or Mauritius, often ending up to sleep in rough housing and withstand poor living conditions. This situation remained, and in 2010, the UK delcared that the Chagos Archipelago would become a marine reserve, despite unanimous statements from the Court of Arbitration that held that the move violated international law. Many former residents and descendents of residents of Chagos have challenged the UK parliament on this, demanding the right to return home to re-establish their way of life. The principal group spearheading this, the Chagos Refugee Group, is led by the campaigner Louis Oliver Bancoult, who was removed from Chagos at the age of 4.

The Chagos group is a combination of different coralline rock structures topping a submarine ridge running southwards across the centre of the Indian Ocean, formed by volcanoes above the Réunion hotspot. Unlike the Maldives, there is no clearly discernible pattern in the atoll arrangement, which makes the whole archipelago look somewhat chaotic. Most of the coralline structures of the Chagos are submerged reefs. The Chagos contain the world's largest coral atoll, The Great Chagos Bank, which supports half the total area of good quality reefs in the Indian Ocean. As a result, the ecosystems of the Chagos have so far proven resilient to climate change and environmental disruptions. The Chagos Archipelago has a tropical oceanic climate; hot and humid but moderated by trade winds. Climate is characterised by plenty of sunshine, warm temperatures, showers and light breezes. December through February is considered the rainy season (summer monsoon); typical weather conditions include light west-northwesterly winds and warmer temperatures with more rainfall. June to September is considered the drier season (winter), characterised by moderate south-easterly winds, slightly cooler temperatures and less rainfall. The annual mean rainfall is 2600 mm (100 inches), varying from 105 mm (4 inches) during August to 350 mm (14 inches) during January.

Louis Olivier Bancoult[]

Louis Olivier Bancoult was four when he left his homeland, a palm-covered island in the middle of the Indian Ocean. He was exiled with the rest of the population of the Chagos archipelago, one of Britain's last colonial outposts. Dumped 1,900km away in Mauritius, Bancoult and his compatriots were left in abject poverty, without shelter, food or jobs. Today, Olivier Bancoult is President and co-founder of the Chagos Refugees Group (CRG). Under Bancoult’s leadership, for more than thirty years the CRG has promoted the welfare, interests, and rights of the exiled Chagossian people living in Mauritius, the Seychelles, and the UK. Bancoult, a fifty-year-old electrician by training, has gained international acclaim for fighting for Chagossians’ right to return to their homeland and for leading his people to victories in three lawsuits against the British government, which controls Diego Garcia. In 2000, 2006, and 2007, the British High Court ruled that the removal of Bancoult’s people from their homeland was illegal; however, the victories were overturned in 2008 by a 3-2 decision in the House of Lords.

Undeterred, Bancoult has continued to lead the Chagossians’ legal and political struggle to return to their homeland and gain proper reparations for their expulsion. Bancoult has represented the Chagossians in London and Washington, DC, at the United Nations and the Vatican, and at numerous international forums in Europe, Africa, and Asia. With a newly published British government study finding no legal barriers to a return and the renewal of US/UK negotiations over the Diego Garcia base agreement, Bancoult visited the United States in 2015, to call on the Obama Administration and United Nations delegations to support Chagossians’ right to return, resettlement assistance, and justice for the Chagossians, and has challenged the UK Parliament as recently as December 2016, in 2019, 2020 and 2021 on their right to return.

Esteemed leader, your people look to you to challenge the unshakeable courts, to return to them their way life which was so cruelly taken from them. Can you achieve the goal of independence? Can you build a civilization that can stand the test of time?

Introduction: "Bonzur, and welcome to Chagos. My people have fought hard to establish their right to call this home. Do you accept this, or seek to take it away from us?"
