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 categorise one group of human beings as "goods", in order for the owner of these goods to be able to obtain insurance money and compensation in case of loss of his "goods". The 1735 arrival of French governor Bertrand-François Mahé de La Bourdonnais coincided with development of a prosperous economy based on sugar production. Mahé de La Bourdonnais established Port Louis as a naval base and a shipbuilding centre. 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. During the French rule slaves were brought from parts of Africa such as Mozambique and Zanzibar. As a result, the island's population rose dramatically from 15,000 to 49,000 within thirty years. 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. 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.
