Does the Buddhist religion have a mythology for the end of the world, a messiah and an established kingdom?

Answer 1

According to the Buddhist holy scripture, the Tipitaka, we’ll know the end of the world is coming when morality disappears and people start following the "10 Amoral Concepts." Those concepts? Theft, violence, murder, lying, evil speaking, adultery, idle talk, covetousness, greed, and perverted lust.

And Then: Once morality disappears, things will degenerate into misery.

Until: A Buddha named Maitreya (known in English as the "future Buddha"), the successor to the Buddha we all know and love, will arrive on earth and begin teaching the pure Dharma.
