The son of a prominent Sussex supporter of Robert Dudley†, earl of Leicester, Shirley joined Leicester’s expedition to the Netherlands in 1585, commanding a cavalry troop until 1588. The following year he served for a short period in an unknown capacity in Ireland, where he was knighted. In 1591 he was imprisoned for secretly marrying one of Elizabeth’s maids of honour, but was released in the following spring. He returned to the Netherlands in 1597, this time as captain of an infantry company, after his father, the treasurer-at-war, went bankrupt and was disgraced. He subsequently became a privateer, hoping thereby to recover his family’s fortunes, although he commanded a naval vessel in 1599.
According to a letter he subsequently wrote to James I, Shirley was, in the late Elizabethan period, an ardent proponent of the Scottish succession and offered to ‘attempt to take from the Turk ... his treasure’ in order that he might ‘lay it down’ at James’ feet.
On his return late in 1606, Shirley wrote his Discours of the Turkes, which included a lengthy description of his journey home as well as an account of the Ottoman Empire. Although it was not published until the 1930s, Shirley probably circulated it in manuscript, which helped turn him into something of a popular hero. A book was written and a play performed about his exploits, and those of his more adventurous younger brothers, Robert and Anthony.
Shirley had financial dealings with the Sephardic Jewish community in the Mediterranean, and, with the tightening persecution in the Iberian Peninsula, he wrote to the king in 1607 to propose the readmission of the Jews to his dominions, especially Ireland, where he thought they would transform the economy.
Shirley was released from the Tower in December, and in the following year he purchased a grant of old debts from the Crown for £9,000, which he promised to pay in instalments.
The death of his father in 1612 left Shirley heir to a ruined estate, but it included an interest in the manor of Wiston. However attenuated, it assured him of election at Steyning, two miles away, which he seems to have valued largely for the protection bestowed by membership. He was returned for the borough in 1614, but he only appears once in the surviving records, on 31 May, when he was appointed to ‘consider of some course concerning the old debts’.
A month after the dissolution of the Addled Parliament Shirley obtained royal protection for one year.
His first wife having died, Shirley remarried in December 1617. Three years later he was returned for Steyning for the last time. He received no committee appointments, but made one recorded speech, on 19 Feb. 1621, when he indignantly denied that he owed anything to the warden of the Fleet, ‘never having been in the Fleet since this warden’s time’.
In 1622, with the reluctant consent of his mother, Shirley finally relinquished his hold on Wiston to the earl of Middlesex (Sir Lionel Cranfield*).
Shirley seems to have died in Westminster, as he was buried in St. Clement Danes on 13 Dec. 1632. No will or grant of administration has been found and no later member of the family sat in Parliament. Sir Edward Bishopp* murdered one of his sons, Henry, a minor dramatist. His eldest surviving son, Thomas, a professional soldier, was knighted while in royalist service in 1646, and a grandson, also Thomas, a Court physician, precipitated a conflict between the Lords and the Commons in 1675 while pursuing a claim to Wiston, then in the hands of Sir John Fagg†.
