Bhojpuri is a dialect of Hindi and has its origins from a place called Bhojpur located in Eastern UP/Bihar area of Northern India. The Bhojpuri Speaking Belt ranges from Eastern Uttar Pradesh to Bihar.
Bhojpuri Speaking People are characterised by their frankness, straightforwardness and their melody in the accent.
In other parts of India, at about the same time, the Bhojpuri Speaking People moved and set up homes away from their ancestral villages. The poor people of Bhojpuri region have been forced to leave the land in the absence of employment opportunities in and around this region. The lack of infrastructures for vocational training forced them to resort to work as construction workers in south and west India, as farm workers in Punjab and Haryana, as coolies in almost all the cities of North India, as Rickshaw Pullers in Kolkata and Delhi, as Taxi Drivers in Mumbai (almost 90% from UP) and Kolkata (almost 95% from Bihar), as Pan-walas and Chai-walas every where.
