Some of the Ivy League schools have identifiable Protestant roots, while others were founded as non-sectarian schools. "King's College" was founded at the behest of King George II of Great Britain and the Church of England, but renamed Columbia College following the American revolution. In the early nineteenth century, the specific purpose of training Calvinist ministers was handed off to theological seminaries, but a denominational tone and such relics as compulsory chapel often lasted well into the twentieth century. Penn and Brown were officially founded as nonsectarian schools. Brown's charter promised no religious tests and "full liberty of conscience", but placed control in the hands of a board of twenty-two Baptists, five Quakers, four Congregationalists, and five Episcopalians. Cornell has been strongly nonsectarian from its founding.
