Tripoli, today the capital city of Libya, was ruled by the Knights Hospitaller between 1530 and 1551. The city had been under Spanish rule for two decades before it was granted as a fief to the Hospitallers in 1530 along with the islands of Malta and Gozo. The Hospitallers found it difficult to control both the city and the islands, and at times they proposed to either move their headquarters to Tripoli or to abandon and raze the city. Hospitaller rule over Tripoli ended in 1551 when the city was captured by the Ottoman Empire following a siege.

A langue or tongue was an administrative division of the Knights Hospitaller between 1319 and 1798. The term referred to a rough ethno-linguistic division of the geographical distribution of the Order's members and possessions. Each langue was subdivided into Priories or Grand Priories, Bailiwicks and Commanderies. Each langue had an auberge as its headquarters, some of which still survive in Rhodes, Birgu and Valletta.
