This document summarizes the history of migration from the rural Bihar region of India. It discusses both colonial-era forced migration as well as post-colonial voluntary migration in the 19th and 20th centuries. During the colonial period, a large number of Bihari laborers were forcibly migrated as indentured workers to other British colonies. Within India, Biharis migrated to work on rice and jute plantations in Bengal. In the post-colonial period, Bihar continued to experience large-scale voluntary migration to other states like Punjab due to better wages and employment opportunities in agriculture and other odd jobs. Higher earnings potential induced Biharis to accept lower wage work elsewhere.
