This illustrated presentation by Liam Riordan explores the long statehood process in Maine, which culminated in 1820, with formal separation from Massachusetts. That struggle engaged a range of challenging public issues that are still recognizable in contemporary Maine politics and culture. The talk focusses on four themes that bridge 200 years in telling ways: the “two Maines” and sharp partisan conflict, the explosive place of slavery vis-a-vis the Maine-Missouri Compromise, Wabanaki sovereignty, and the uncertain location of the international border to at least 1842. Professor Riordan is planning a scholarly conference (that will be open to the public) in Orono and Augusta in early June 2019.
