How is buddhism unique from other religions?

Buddhism and Hinduism have common origins in the Ganges culture of northern India during the so - called "second urbanisation" around 500 BCE.[1] They have shared parallel beliefs that have existed side by side, but also pronounced differences.

Buddhism attained prominence in the Indian subcontinent as it was supported by royal courts, but started to decline after the Gupta era and virtually disappeared from India in the 11th century CE, except in some pockets. It has continued to exist outside of India and has become the major religion in several Asian countries.
