[1][2][3] These immigrants came primarily from what are now known as the Indian States of Bihar, Uttar Pradesh, Jharkhand, West Bengal, Odisha, Maharashtra, Tamil Nadu, Telangana and Andhra Pradesh; with later on another influx of free immigrants from the Indian States of Gujarat, Rajasthan, Punjab and lastly from the Sindh Province of Pakistan, following the Partition of India.

However, the demand kept rising for low cost, high intensity labor in colonial plantations of sugarcane, cotton, tobacco and other cash crops.

[9] The Hindus, and non-Hindus, who accepted indentured labour contracts and were brought to Mauritius, faced difficult conditions in India.

According to Michael Mann – a professor of sociology, the Hindus and non-Hindus of India who arrived in Mauritius were a small percentage of the over 30 million indentured Indian workers shipped around the colonial world between the 18th and early 20th century (many of whom returned after serving for years as plantation labour).

[15] The politically active Hindus, states Eisenholr, have attempted to preserve Hindi by calling it their mother tongue and ancestral language, as well as an assurance against the colonial discrimination they faced, but most Hindus mainly use Mauritian Creole in their daily lives – a syncretic language of Indians and Africans that has developed on the island.

These settlements are of Hindus primarily hailing from the Gangetic plain regions of western Bihar State and eastern Uttar Pradesh State of India, and their language is a modified form – a koiné in linguistic studies – of the original Bhojpuri that is spoken in India by the Bhojpuri people.

Another relatively modern form of stratification emerged in 1983 when the MMM attempted to isolate the Hindi-speaking Hindus by inventing a new group called TTM which abbreviates "Tamil, Telegu, Marathi".
