Matthew Prior (1664-1721) was associated under the Whigs with the negotiation of the treaty of Ryswick in 1697 ending the war with France and under the Tories with that of Utrecht in 1714 ("Matt's Peace") ending the War of the Spanish Succession, but on the Whigs' return to power he was imprisoned by the government leader Walpole 1715-1717. His gift as a poet was for light occasional verses.
