The Bhojpuri region encompasses parts of the Indian states of Bihar, Uttar Pradesh, and Jharkhand, and the Madhesh, Gandaki and Lumbini provinces of Nepal.

[10][11] The Bhojpuri region received its name after the town of Bhojpur (Arrah), the headquarters of the Ujjainiya Rajputs of the former Shahabad district of Bihar.

[12] Most of the Bhojpuri region lies in the fertile Gangetic plains, with highlands present in its northern, southern, and southwestern areas.

The region is traversed by numerous rivers originating from the Himalayas, which enrich the soil and make it highly productive for agriculture.

Additionally, several other rivers flowing through the region, originate from the Chhota Nagpur Plateau, as well as the Kaimur, Vindhya, and Satpura ranges.

The culture of Bhojpur is also very much present today in Trinidad and Tobago, Jamaica, Guyana, Suriname, Fiji, Mauritius, and South Africa, due to the many Indian indentured laborers who were sent there by the ruling British in the mid 19th century to the early 20th century, and were from the Purvanchal-Bhojpur region.Bhojpuri language is a descendant of Magadhi Prakrit which started taking in shape during the reign of the Vardhana dynasty.

Men in the Bhojpuri region traditionally wear Dhoti, Ganji, Kurta, Lungi, and carry a Gamchha, often used as a turban (Muraitha).
