The document discusses the concepts of land and evolution of land tenure systems in Jharkhand, India. It describes how tribals were originally the settlers in Jharkhand and held land communally. Over time, as populations increased, a chieftain system developed to coordinate villages. The Nagbanshi dynasty was established in the 13th century to govern the region. Later invasions by outsiders pushed tribals further into forests. Under Mughal rule in the 16th century, Jharkhand became a tributary state and the Raja introduced land grants to court officials to pay tribute, establishing a jagirdari system and reducing tribals to tenants.
