The Capture of Hormuz was a combined Anglo-Persian expedition that successfully captured the Portuguese garrison at Hormuz Island after a ten-week siege, thus opening up Persian trade with England in the Persian Gulf. Before the capture of Hormuz, the Portuguese had held the Castle of Hormuz for more than a century, since 1507 when Afonso de Albuquerque established it in the capture of Hormuz, giving them full control of the trade between India and Europe through the Persian Gulf. According to Stephen Neill, the capture of Hormuz entirely changed the balance of power and trade.
