After the Portuguese made several abortive attempts to seize control of Basra, the Safavid ruler Abbas I of Persia conquered the kingdom with the help of the English, and expelled the Portuguese from the rest of the Persian Gulf, with the exception of Muscat. The Portuguese returned to the Persian Gulf in the following year as allies of Afrasiyab, the Pasha of Basra, against the Persians. Afrasiyab was formerly an Ottoman vassal but had been effectively independent since 1612. They never returned to Ormus.
