Following the November 1810 British Invasion from the northern coast, the island came under British rule. With the liberation of about 65,000 African and Malagasy slaves after the 1833 abolition of slavery the Franco-Mauritian plantation owners and sugar oligarchs resorted to indentured labourers, or Coolies, from various parts of India to work in their fields. Between 1834 and 1920, nearly 700,000 Indian indentured laborers arrived at Aapravasi ghat, an embankment located in the harbor of Port-Louis. Mauritius thus became the British colony's largest recipient of indentured migrants. Indentured labourers were mostly brought from the Bhojpuri speaking regions of Bihar and Uttar Pradesh, with a large number of Tamils, Telugus and Marathis amongst them. The descendants of these indentured labourers make up two-thirds of the island's current population.
