During the Napoleonic Wars, the island was invaded by a Royal Navy squadron led by Commodore Josias Rowley in 1810, who used the old name of “Bourbon”.
When it was restored to France by the Congress of Vienna in 1815, the island retained the name of “Bourbon” until the fall of the restored Bourbons during the French Revolution of 1848, when the island was once again given the name “Île de la Réunion”.
From the 17th to 19th centuries, French colonization, supplemented by importing Africans, Chinese and Indians as workers, contributed to ethnic diversity in the population. From 1690, most of the non-Europeans were enslaved. The colony abolished slavery on 20 December 1848. Afterwards, many of the foreign workers came as indentured workers. The opening of the Suez Canal in 1869 reduced the importance of the island as a stopover on the East Indies trade route.
During the Second World War, Réunion was under the authority of the Vichy regime until 30 November 1942, when Free French forces took over the island with the destroyer Léopard.
Réunion became a département d’outre-mer (overseas département) of France on 19 March 1946.
Over about two decades in the late 20th century (1963–1982), 1,630 children from Réunion were relocated to rural areas of metropolitan France, particularly to Creuse, ostensibly for education and work opportunities. That program was led by influential Gaullist politician Michel Debré, who was an MP for Réunion at the time. Many of these children were abused or disadvantaged by the families with whom they were placed. Known as the Children of Creuse, they and their fate came to light in 2002 when one of them, Jean-Jacques Martial, filed suit against the French state for kidnapping and deportation of a minor. Other similar lawsuits were filed over the following years, but all were dismissed by French courts and finally by the European Court of Human Rights in 2011.
In 2005 and 2006, Réunion was hit by a crippling epidemic of chikungunya, a disease spread by mosquitoes. According to the BBC News, 255,000 people on Réunion had contracted the disease as of 26 April 2006. The neighboring islands of Mauritius and Madagascar also suffered epidemics of this disease during the same year. A few cases also appeared in mainland France, carried by people travelling by airline. The French government of Dominique de Villepin sent an emergency aid package worth €36 million and deployed about 500 troops in an effort to eradicate mosquitoes on the island.
Geography:
The island is 63 km (39 mi) long; 45 km (28 mi) wide; and covers 2,512 km2 (970 sq mi). It is above a hotspot in the Earth’s crust. The Piton de la Fournaise, a shield volcano on the eastern end of Réunion Island, rises more than 2,631 m (8,632 ft) above sea level and is sometimes called a sister to Hawaiian volcanoes because of the similarity of climate and volcanic nature. It has erupted more than 100 times since 1640, and is under constant monitoring, most recently erupting on 29 July 2019. During another eruption in April 2007, the lava flow was estimated at 3,000,000 m3 (3,900,000 cu yd) per day. The hotspot that fuels Piton de la Fournaise also created the islands of Mauritius and Rodrigues.
