Brought in as slaves to work the plantations of Mauritius (as well as Réunion and Seychelles), the slaves were Africans mostly brought from East African Mozambique, Malawi, Tanzania, Madagascar and Zambia with smaller numbers from West Africa.
The Mauritian Creoles of today are largely an admixture of African, Indian and European (French/English).
The majority of Creoles are Roman Catholic. There is also a non-religious minority as well as some Islamic converts. Due to increased connection with other African diaspora most notably from the Caribbean there are some Rastafarians. The mother tongue of Mauritians is the Mauritian Creole, French and English are also spoken as second or third language.
