Christianity first came to Mauritius with the first inhabitants, the Dutch. However, the Dutch abandoned the island in 1710. The French brought Christianity again when they arrived in 1715. From 1723, there was a law whereby all slaves coming to the island must be baptised Catholic. This law does not seem to have been strictly adhered to. After they had taken Mauritius from the French during the Napoleonic Wars, the British tried to turn Mauritius Protestant during the 1840s and 1850s.
Franco-Mauritians, usually having the same religion and denomination as the Creoles, have sometimes emphasised their differences from the Creoles by practising more traditionally, for instance celebrating Mass in Latin.
