India until the 13th century, often referred to as Greater India, extended its religious, cultural, and trading influence on vast Asian regions from Iran and Afghanistan to Malaysia, Indonesia and Cambodia. With Buddhism and Hinduism, two of the most followed religions in Asia and the World as a whole, having originated there, India's cultural impact spread throughout Asia. A notable example is China, where Buddhism became the prominent religion. Sanskrit was a prominent scholarly language in all the southeastern kingdoms until the 10th century C.E.. Angkor Vat of Cambodia, the largest temple complex in the world, was originally a Hindu temple and later transformed into a Buddhist monastery.
