Hinduism originated around 4000 BC in the Indus River Valley region of the Indian subcontinent. Its beliefs integrated over time as Aryan invaders introduced their own system around 1500 BC. Key texts like the Vedas and Upanishads were written between 1700-500 BC and formed Hindu traditions. Hinduism is characterized by beliefs in dharma, reincarnation, and many deities including Brahma, Vishnu, Shiva, and goddess figures representing the divine feminine creative force.
