What colony did roger williams purchase after being banished from massachusetts?

After leaving Massachusetts, Williams, with the assistance of the Narragansett tribe, established a settlement at the junction of two rivers near Narragansett Bay, located in present-day Rhode Island. He declared the settlement open to all those seeking freedom of conscience and the removal of the church from civil matters, and many dissatisfied Puritans came. Taking the success of the venture as a sign from God, Williams named the community "Providence."

Among those who found a haven in the religious and political refuge of the Rhode Island Colony were Anne Hutchinson-like Williams, she had been exiled from Massachusetts for religious reasons-some of the first Jews to settle in North America, and the Quakers. In Providence, Roger Williams also founded the first Baptist church in America and edited the first dictionary of Native-American languages.
