Sir Robert Shirley was an English traveller and adventurer, younger brother of Sir Anthony Shirley and Sir Thomas Shirley. He is notable for his help modernising and improving the Persian Safavid army according to the British model, by the request of Shah Abbas the Great. This proved to be highly successful, as from then on the Safavids proved to be an equal force to their archrival, the Ottoman Empire.
Double portrait of Robert Shirley and his Circassian wife Teresia, c.1624–1627. He wears the exotic Persian clothes which so impressed his European hosts upon his return to Europe from Persia; she wears her native style of dress but also holds a flintlock pistol and a pocket watch, symbols of the technologies Europe was introducing to Persia.

Sir Anthony Shirley (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.
Shirley convinced the Persian ruler to send a Persian embassy to Europe in 1599.
