Arminianism was started by Jacobus Arminius (1560-1609). He was born slightly before John Calvin died and was actually taught by Calvin's son-in-law. He was a Calvinist until one day when forced to defend his beliefs and found that his opponent could more ably defend his views against Calvinism. This caused Arminius to reject his Calvinistic background and “sought to modify Calvinism so that ‘God might not be considered the author of sin, nor man an automation in the hands of God.’”
