Trucial States
Later in the 16th century the Portuguese would battle the then dominant force in the Persian Gulf, the Safavid dynasty, for control of the region. During the 17th century, the Ottomans took control of the islands and UAE was known as the "Pirate Coast." By the 19th century, the British Empire had taken complete control of the land then called the Trucial States. Oil was discovered in 1959. The Trucial States were under the control of the British Empire until 1971. Consequently, with weakening British control, the Trucial States became the UAE in 1971 with Ras al-Khaimah joining in 1972.
