The Vedic Period, spanning from around 1500 BCE to 600 BCE, marks a pivotal era in Indian history characterized by significant developments in society, religion, politics, and culture. It is distinguished by the composition of the Vedas, the earliest sacred texts of Hinduism, and is divided into the Early Vedic and Later Vedic periods. Notable changes include the evolution of political structures from tribal assemblies to hereditary monarchies, social stratification with the rigid varna system, economic shifts to agriculture, and the transition from nature worship to complex rituals and philosophical thought.
