After sending Occom and another minister on a speaking tour of England to raise money for the charity school, Wheelock decided to enlarge it, as well as adding college classes for the education of American colonists in the classics, philosophy, and literature. He began to search for another location for the schools. Wheelock obtained a charter from King George III on December 13, 1769. Having worked and raised funds for the education of Native Americans, Occom and the British Board of Trustees headed by Lord Dartmouth opposed the addition of the college to benefit the son's of the colonists.
