History
In pre-Islamic times, the settlement at the site was called Hajar. The site is at the confluence of several rivers (now wadis) and much underground water is accessible at the site. The settlement was historically famous for its dates and orchards. Its name derives from the plural of the Arabic rowdhah (place of gardens). The modern name was first applied to only certain parts of the settlement where orchards predominated. Gradually the name was used for the entire settlement.
By the end of the 18th century, Riyadh was part of the First Saudi State, with the capital at Dariyah. After the destruction of Dariyah in 1818 by the Turks, the capital moved to Riyadh.
The city was seized in 1902 by Abdul Aziz bin Abdul Rahman Al Saud. He went on to established the modern Kingdom of Saudi Arabia in 1932, with Riyadh the capital of the nation. The diplomatic capital did not move until 1982 (from Jiddah). Recently the city has experienced very high rates of population growth, which is indicated by the poor quality of development since the 1970s.
