People of the land
Most Punjabis have belonged to a zat or biradari, a community of birth, as well as to a faith, and the two cut across each other. There are Muslim, Sikh and Hindu Jats, Muslim and Hindu Rajputs and Gujjars, Sikh and Hindu Khatris, and Dalit communities in every faith. The Gurus and the Sufis taught that birth counts for nothing before God, and the langar was built on that teaching; yet zat shaped who married whom, who owned land, and who worked it, in every faith.
British officials made the categories harder than they had been. Denzil Ibbetson's Punjab Castes (1883) and H. A. Rose's Glossary of the Tribes and Castes (1911–19) catalogued every community, often with crude judgements of character, and the Punjab Alienation of Land Act of 1900 allowed land to be sold only to communities listed as agricultural tribes. This page describes the main communities as historians now see them, without ranking them.
Areas are approximate: where each community was most concentrated before 1947. Every community also lived far beyond them.
