The Jat people, also spelt Jaat and Jatt, are a traditionally agricultural caste in Northern India and Pakistan. Originally pastoralists in the lower Indus river-valley of Sindh, many Jats migrated north into the Punjab region in late medieval times, and subsequently into the Delhi Territory, northeastern Rajputana, and the western Gangetic Plain in the 17th and 18th centuries. Of Hindu, Muslim and Sikh faiths, they are now found mostly in the Indian states of Punjab, Haryana, Uttar Pradesh and Rajasthan and the Pakistani regions of Sindh, Punjab and AJK.
