Indo-Surinamese are nationals of Suriname of Indian or other South Asian ancestry. After the Dutch government signed a treaty with the United Kingdom on the recruitment of contract workers, Indians began migrating to Suriname in 1873 from what was then British India as indentured labourers, mostly from the modern-day Indian states of Uttar Pradesh, Bihar and the surrounding regions. Just before and just after the independence of Suriname on 25 November 1975 many Indo-Surinamese emigrated to the Netherlands.
