Hinduism is the major religion of India and is one of the world’s great religions. It differs from Christianity and other Western religions in that it does not have a single founder, a particular theological system, a single system of ethics, or religious organization. The development of Hinduism was influenced by many invasions over thousands of years. One of the major influences occurred from the steppes of Russia and Central Asia when Indo-Europeans invaded Northern India (circa 1500 to 500 BCE) and brought with them their religion of Vedism. These beliefs then became mixed with the indigenous Indian native beliefs.
