<P> From 1708 to 1709 he was MP for the rotten borough of Lostwithiel .

From 1710, he represented Malmesbury, in his home county of Wiltshire, holding the seat until his death . </P> <P> He encountered Jonathan Swift in Ireland and remained there for a year . Subsequently, he helped found the Kitcat Club and renewed his association with Richard Steele . In 1709 Steele began to bring out Tatler, to which Addison became almost immediately a contributor: thereafter he (with Steele) started The Spectator, the first number of which appeared on 1 March 1711 . This paper, which at first appeared daily, was kept up (with a break of about a year and a half when The Guardian took its place) until 20 December 1714 . His last undertaking was The Freeholder, a political paper, 1715--16 . </P> <P> He wrote the libretto for Thomas Clayton's opera Rosamond, which had a disastrous premiere in London in 1707 . In 1713 Addison's tragedy Cato was produced, and was received with acclamation by both Whigs and Tories . He followed this effort with a comedic play, The Drummer (1716). </P> <P> In 1712, Addison wrote his most famous work of fiction, Cato, a Tragedy . Based on the last days of Marcus Porcius Cato Uticensis, it deals with such themes as individual liberty versus government tyranny, Republicanism versus Monarchism, logic versus emotion, and Cato's personal struggle to cleave to his beliefs in the face of death . It has a prologue written by Alexander Pope and an epilogue by Dr. Garth . </P>
