Bahrain has roots deep in the past, going back some 5,000 years. It was a vital link between civilisations, such as the Phoenicians, the Levant and Mesopotamia. The 'modern' era of Bahrain began in 1783, following the island's conquest by Ahmed al-Fateh. It has been ruled by the al-Khalifa family since 1961. Bahrain was declared independent from the United Kingdom in August 1971, and issued its first constitution in 1973.
