This document summarizes the origin and evolution of human settlements from early nomadic hunter-gatherer societies to permanent agricultural communities and eventually urban settlements. It describes how early humans lived as nomads in caves up until around 10,000 BC, after which some began living near rivers and practicing basic cultivation. Around 5,000 BC, settlements took shape as groups built huts near fields. Surplus food production led to population growth and more permanent settlements organized under leaders. River valleys were popular locations, and division of labor, trade, social stratification, and fortified settlements with castles and temples emerged. Urban settlements developed with specialized occupations and social classes.
