Considered part of the “pulpit of the American Revolution,” and a leading advocate of the separation of church and state in Revolutionary-era America, Baptist pastor Isaac Backus was a pillar of early American evangelical thought. His works such as Appeal to the Public for Religious Liberty and Government and Liberty Described and Ecclesiastical Tyranny Exposed open a valuable window into early America and the development of the ideals of religious liberty.

Isaac Backus’ history of religious development in New England offers a valuable window into early America and the rise of religious traditions, particularly the Baptists. Primarily created to remedy the lack of attention paid to Baptists and religious oppression in other Puritan histories, Isaac Backus presents a detailed account of important figures and events related to the Baptists.
