Chapter 2, “1641: Ulster’s Historical Repetition Compulsion,” is the only breakout chapter in Frances Molloy: A Portrait of a Postwar Northern Irish Woman Writer in which we discuss the centuries-old “quarrel” between Protestants and Catholics in what was a nine-county ancient Ulster—later gerrymandered into a six-county Northern Ireland. On October 22, 1641, the native Irish of Ulster, led by Sir Phelim O’Neill, staged a successful across-the-board uprising; this uprising is known as the “1641 Massacre” by Protestants who have kept the memory alive through recounting the atrocities. At the same time, Catholics remember the events as the “1641 Uprising” in which they successfully revolted against the colonial invaders who had usurped their land. This chapter discusses the origins of the repetitive history of Ulster which directly dictated the course of Molloy’s life and her ancestors’ lives down to the present. In Ulster and County Derry, specifically, the early modern period of James I’s plantation scheme demarcated the beginning of a cycle of history that present-day inhabitants of Northern Ireland still enact.
