Abstract This chapter explores several aspects of William Penn’s political career during the 1690s: the ongoing difficulties that his colony continued to cause him (including the Keithian schism in Pennsylvania’s Quaker community), Penn’s 1693 Essay toward the present and future peace of Europe, and finally the legal and political implications of his eventual return to Pennsylvania at the end of the decade. None of these episodes rises to the level of the events that had first made Penn a public figure and kept him in the public eye for more than twenty years; and he engaged in little explicit political theorizing during the 1690s. Yet each one illustrates Penn’s ongoing involvement in public affairs and the ways in which the political principles that he had refined during the 1670s and 1680s continued to shape his thinking about politics, as the eighteenth century approached and he attempted to return to Pennsylvania.
