Thomas Percy

Who was Thomas Percy?

Thomas Percy was a member of the group of provincial English Catholics who planned the failed Gunpowder Plot of 1605. A tall, physically impressive man, little is known of his early life beyond his matriculation in 1579 at the University of Cambridge, and his marriage in 1591 to Martha Wright. In 1596 a distant relation, Henry Percy, 9th Earl of Northumberland, appointed him constable of Alnwick Castle and made him responsible for the Percy family's northern estates. He served the earl in the Low Countries in about 1600–1601, and in the years before 1603 was his intermediary in a series of confidential communications with King James VI of Scotland.

Following James's accession to the English throne in 1603, Percy became disenchanted with the new king, who he supposed had reneged on his promises of toleration for English Catholics. His meeting in June 1603 with Robert Catesby, a religious zealot similarly unimpressed with the new royal dynasty, led the following year to his joining Catesby's conspiracy to kill the king and his ministers by blowing up the House of Lords with gunpowder.
