Who Founded Buddhism?

Buddhism was founded in around 540 BC, by Siddhartha Gautama.  He was in fact a royal prince who was born in 563 BC.  Siddharta found himself somewhat at odds with the major religions of that time and spent may years praying and meditating.  He felt that through this meditation, prayer and simple life style, he achieved enlightenment.  The title Buddha actually means awakening or enlightenment.
Buddhism is a very gentle faith, believing in non violence, to other living things, gentleness, striving to make the world a better place and living a good life.  Following the middle path between luxury and hardship.
Unlike other faiths, Buddhists do not believe in a God or Supreme Being.  However, they believe that after death they will be re-born.  If they have led a good life their next life will be better.  A bad life means the next will be worse.  Their aim is to avoid this rebirth cycle and to achieve a state of enlightenment or nirvana.

Siddhartha, born in 563 B.C.to King Shuddhodana of Kapilvastu and soon-to-be dying Queen Mayadevi,and brought up by stepmother Gautami after whose name he came to be called Gautam, founded Buddhism after he got enlightenment regarding the cause of the worldly sorrow and the remedy for it.

Buddhism was founded around the 5th century BCE by Siddhartha Gautama who was later known as "the Buddha".
