The Treaty of Tordesillas, designed to prevent conflict between Portugal and Spain, gave the Kingdom of Portugal the right to colonise this part of the world. In 1507, Portuguese sailors came to the uninhabited island and established a visiting base. Diogo Fernandes Pereira, a Portuguese navigator, was the first European known to land in Mauritius. He named the island "Ilha do Cisne" ("Island of the Swan"). The Portuguese did not stay long as they were not interested in these islands.[40] The Mascarene Islands were named after Pedro Mascarenhas, Viceroy of Portuguese India, after his visit to the islands in 1512. Rodrigues Island was named after Portuguese explorer Diogo Rodrigues, who first came upon the island in 1528. Dutch activities on Mauritius, as well as the first published depiction of a dodo bird (2), 1601 In 1598, a Dutch squadron under Admiral Wybrand Van Warwyck landed at Grand Port and named the island "Mauritius" after Prince Maurice of Nassau (Dutch: Maurits van Nassau) of the Dutch Republic. The Dutch inhabited the island in 1638, from which they exploited ebony trees and introduced sugar cane, domestic animals and deer. It was from here that Dutch navigator Abel Tasman set out to seek the Great Southern Land, mapping parts of Tasmania, New Zealand and New Guinea. The first Dutch settlement lasted 20 years. In 1639, the Dutch East India Company brought enslaved Malagasy to cut down ebony trees and to work in the new tobacco and sugar cane plantations.[41] Several attempts to establish a colony permanently were subsequently made, but the settlements never developed enough to produce dividends, causing the Dutch to abandon Mauritius in 1710.[40][42] A 1755 article in the English Leeds Intelligencer claims that the island was abandoned due to the large number of long tailed macaque monkeys "which destroyed everything in it," and that it was also known at the time as the Island of Monkeys.[43] Portuguese sailors had brought these monkeys to the island from their native habitat in Southeast Asia, prior to Dutch rule.[44] French Mauritius (1715–1810)[edit] Main article: Isle de France (Mauritius) France, which already controlled neighbouring Île Bourbon (now Réunion), took control of Mauritius in 1715 and renamed it Isle de France. In 1723, the Code Noir was established to regulate slavery; it categorised one group of human beings as "goods", allowing the owner of these "goods" to be able to obtain insurance money and compensation in case of loss of his "goods".[45] The 1735 arrival of French governor Bertrand-François Mahé de La Bourdonnais coincided with the development of a prosperous economy based on sugar production. Mahé de La Bourdonnais established Port Louis as a naval base and a shipbuilding centre.[40] Under his governorship, numerous buildings were erected, a number of which are still standing. These include part of Government House, the Château de Mon Plaisir, and the Line Barracks, the headquarters of the police force. The island was under the administration of the French East India Company, which maintained its presence until 1767.[40] During the French rule, slaves were brought from parts of Africa such as Mozambique and Zanzibar.[46] As a result, the island's population rose dramatically from 15,000 to 49,000 within thirty years. Slave traders from Madagascar - Sakalava or Arabs - bought slaves from slavers in the Arab Swahili coast or Portuguese Mozambique and stopped at Seychelles for supplies before shipping the slaves to the slave markets of Mauritius, Réunion and India.[47] Of the 80,000 slaves imported to Réunion and Mauritius between 1769 and 1793, 45% was provided by slave traders of the Sakalava people in North West Madagascar, who raided East Africa and the Comoros for slaves, and the rest was provided by Arab slave traders who bought slaves from Portuguese Mozambique and transported them to Réunion via Madagascar.[48] During the late eighteenth century, African slaves accounted for around 80 percent of the island's population, and by the early nineteenth century there were 60,000 slaves on the island.[41] In early 1729, Indians from Pondicherry, India, arrived in Mauritius aboard the vessel La Sirène. Work contracts for these craftsmen were signed in 1734 at the time when they acquired their freedom.[49] The Battle of Grand Port between French and British naval forces, 20–27 August 1810 From 1767 to 1810, except for a brief period during the French Revolution when the inhabitants set up a government virtually independent of France, the island was controlled by officials appointed by the French government. Jacques-Henri Bernardin de Saint-Pierre lived on the island from 1768 to 1771, then went back to France, where he wrote Paul et Virginie, a love story that made the Isle de France famous wherever the French language was spoken. In 1796 the settlers broke away from French control when the government in Paris attempted to abolish slavery.[50] Two famous French governors were the Vicomte de Souillac (who constructed the Chaussée in Port Louis[51] and encouraged farmers to settle in the district of Savanne) and Antoine Bruni d'Entrecasteaux (who saw to it that the French in the Indian Ocean should have their headquarters in Mauritius instead of Pondicherry in India).[52] Charles Mathieu Isidore Decaen was a successful general in the French Revolutionary Wars and, in some ways, a rival of Napoléon I. He ruled as Governor of Isle de France and Réunion from 1803 to 1810. British naval cartographer and explorer Matthew Flinders was arrested and detained by General Decaen on the island from 1803 to 1810,[53][54] in contravention of an order from Napoléon. During the Napoleonic Wars, Mauritius became a base from which French corsairs organised successful raids on British commercial ships. The raids continued until 1810, when a Royal Navy expedition led by Commodore Josias Rowley, R.N., an Anglo-Irish aristocrat, was sent to capture the island. Despite winning the Battle of Grand Port against the British, the French could not prevent the British from landing at Cap Malheureux three months later. They formally surrendered the island on the fifth day of the invasion, 3 December 1810,[52] on terms allowing settlers to keep their land and property and to use the French language and law of France in criminal and civil matters. Under British rule, the island's name reverted to Mauritius.[40] British Mauritius (1810–1968)[edit] Main article: British Mauritius British forces seizing the Isle of France on 2 December 1810 First indentured Indian workers (1834) The British administration, which began with Sir Robert Farquhar as its first governor, oversaw rapid social and economic changes. However, it was tainted by the Ratsitatane episode. Ratsitatane, nephew of King Radama of Madagascar, was brought to Mauritius as a political prisoner. He managed to escape from prison and plotted a rebellion that would free the island's slaves. He was betrayed by his associate Laizaf and was caught by a group of militiamen and summarily executed.[55][56] In 1832, d'Épinay launched the first Mauritian newspaper (Le Cernéen), which was not controlled by the government. In the same year, there was a move by the procureur-general to abolish slavery without compensation to the slave owners. This gave rise to discontent, and, to check an eventual rebellion, the government ordered all the inhabitants to surrender their arms. Furthermore, a stone fortress, Fort Adelaide, was built on a hill (now known as the Citadel hill) in the centre of Port Louis to quell any uprising.[51]
