Sir Anthony Shirley (or Sherley) (1565–1635) was an English traveller, whose imprisonment in 1603 by King James I caused the English House of Commons to assert one of its privileges—freedom of its members from arrest—in a document known as The Form of Apology and Satisfaction.
Anthony Shirley was the second son of Sir Thomas Shirley of Wiston, Sussex, and Anne Kempe, the daughter of Sir Thomas Kempe (d. 7 March 1591) of Olantigh in Wye, Kent. He had an elder brother, Sir Thomas Shirley, and a younger brother, Sir Robert Shirley, and six sisters who survived infancy.
Educated at the University of Oxford, Shirley gained military experience with the English troops in the Netherlands and during an expedition to Normandy in 1591 under The 2nd Earl of Essex, who was related to his wife, Frances Vernon; about this time he was knighted by Henry of Navarre (Henry IV of France), an event which brought upon him the displeasure of his own sovereign and a short imprisonment.
In 1596, he conducted a predatory expedition along the western coast of Africa and then across to Central America, but owing to a mutiny he returned to London with a single ship in 1597. In 1598, he led a few English volunteers to Italy to take part in a dispute over the possession of Ferrara; this, however, had been accommodated when he reached Venice, and he decided to journey to Persia with the twofold object of promoting trade between England and Persia and of stirring up the Persians against the Turks. He obtained money at Constantinople and at Aleppo, and was very well received by the Shah, Abbas the Great, who made him a Mirza, or prince, and granted certain trading and other rights to all Christian merchants.
