The coastal region of what is today Libya was ruled by the Ottoman Empire from 1551 to 1911, as the Eyalet of Tripolitania ( Eyalet-i Trâblus Gârb) or Bey and Subjects of Tripoli of Barbary from 1551 to 1864 and as the Vilayet of Tripolitania ( Vilâyet-i Trâblus Gârb) from 1864 to 1911. It was also known as the Kingdom of Tripoli, even though it was not technically a kingdom, but an Ottoman province ruled by pashas (governors). The Karamanli dynasty ruled the province as de facto hereditary monarchs from 1711 to 1835, despite remaining under nominal Ottoman rule.
