44th National Day of the Sultanate of Oman.
His Majesty Sultan Qaboos bi Said, Sultan of Oman.
Soon after Vasco Da Gama's voyage round the Cape of Good Hope and to India, the Portuguese arrived in Oman, occupying the region from 1507. The Portuguese fortified Muscat as used the town as a port from which to protect their trade routes to India.
Unhappy with how they felt the Portuguese were exploiting their presence in Oman, the powerful Al-Ya’ribi clan agreed a treaty with the British East India Company to allow the British to have rights in their ports. This weakened Portuguese control in Oman, and on 18 November 1650, Imam Sultan Bin Saif led a rebellion that expelled the Portuguese from Oman and its ports.
