Capture of Ormuz (1622)

In the 1622 Capture of Ormuz, an Anglo-Persian force combined to take over the Portuguese garrison at Hormuz Island, thus opening up Persian trade with England in the Persian Gulf. Before the capture of Ormuz, the Portuguese had held the Castle of Ormuz for more than a century, since 1507 when Afonso de Albuquerque established it in the Capture of Ormuz, giving them full control of the trade between India and Europe through the Persian Gulf. "The capture of Ormuz by an Anglo-Persian force in 1622 entirely changed the balance of power and trade".

Anglo-Persian alliance
The English side consisted of a force supplied by the English East India Company consisting of five warships and four pinnaces. The Persians had recently gone to war with the Portuguese, and a Persian army was besieging the Portuguese fort in Kishm, but English help was needed to capture Ormuz. Shah Abbas wished to obtain English support against the Portuguese, and the commander Imam Kuli Khan, son of Allahverdi Khan, negotiated with the English to obtain their support, promising the development of silk trade in their favour. An agreement was signed, providing for the sharing of spoils and customs dues at Hormuz, the repatriations of prisoners according to their faith, and the payment by the Persians of half of the supply costs for the fleet.

Operations
The English fleet first went to Kishm, some 15 miles away, to bombard the Portuguese position. The Portuguese quickly surrendered, and the English casualties were few, but included the famous explorer William Baffin.

The Anglo-Persian fleet then sailed to Ormuz and the Persians disembarked to capture the town. The English bombarded the castle and sank the Portuguese fleet, and Ormuz was finally captured on 22 April 1622. The Portuguese were forced to retreat to another base at Maskat.

Although Portugal and Spain were in a dynastic union between 1580–1640, England and Portugal were not at war, the Duke of Buckingham threatened to sue the Company, but he removed his claim when he received the sum of 10,000 pounds, supposedly 10% of the proceedings of the capture of Ormuz. James I also received the same sum when he complained "Did I deliver you from the complaint of the Spaniards, and do you return me nothing".

The capture of Ormuz gave the opportunity to the Company to develop trade with Persia, attempting to exchange English cloth and other artifacts for silk, but only with difficulty. The English adventurer Robert Shirley also took an interest in developing this trade.
