After the end of slavery, the West Indian sugar colonies tried the use of emancipated slaves, families from Ireland, Germany and Malta and Portuguese from Madeira. All these efforts failed to satisfy the labour needs of the colonies due to high mortality of the new arrivals and their reluctance to continue working at the end of their indenture. On 16 November 1844, the British Indian Government legalised emigration to Jamaica, Trinidad and Demerara (Guyana). The first ship, the Whitby, sailed from Port Calcutta for British Guiana on 13 January 1838, and arrived in Berbice on 5 May 1838. Transportation to the Caribbean stopped in 1848 due to problems in the sugar industry and resumed in Demerara and Trinidad in 1851 and Jamaica in 1860.
