During his extraordinarily long career as an actor, Charles Macklin wrote several plays. The earliest is King Henry VII; or, The Popish Imposter, a tragedy based on the Perkin Warbeck story, performed at Drury Lane 18 January 1745/6 and published the same year. As the Preface states, it “was design’d as a Kind of Mirror to the present Rebellion”; and it provided the author with a part in which he could express, through the character of Lord Huntley, his own aversion to foreign influences in the land, to “French and Priest-rid Weakness” and “Romish Tyranny.” This and his succeeding plays were obviously composed to provide parts for himself; so no others were published until he had retired. They were his stock in trade, since Macklin seldom maintained a stable connection with one of the theatres. Instead he appeared now here now there for brief engagements or on special occasions, rather than as a regular member of the company, often carrying his plays with him. Thus a number have survived only in manuscript.
