Tripoli is the capital and largest city in Libya. It is also known as Tripoli-of-the-West (Arabic: طرابلس الغرب‎ Ṭarābulus al-Gharb), to distinguish it from Tripoli, Lebanon. It is affectionately called The Mermaid of the Mediterranean (Arabic: عروسة البحر‎ ʼarūsat el-baḥr; lit: "bride of the sea"), describing its turquoise waters and its whitewashed buildings. Tripoli (English pronunciation: /ˈtrɪpɵli/) is a Greek name that means "Three Cities", introduced in Western European languages through the Italian Tripoli. In Arabic: طرابلس‎ it is called Ṭarābulus ( pronunciation (help·info), Libyan Arabic: Ṭrābləs  pronunciation (help·info), Berber: Ṭrables, from Ancient Greek: Τρίπολις Trípolis). As of 2011, the Tripoli metropolitan area (district area) had a population of 2.2 million. The city is located in the northwest part of the country on the edge of the desert, on a point of rocky land projecting into the Mediterranean and forming a bay.

The city includes the Port of Tripoli and the country's largest commercial and manufacturing centre. It is also the site of the University of Tripoli. The vast Bab al-Azizia barracks, which includes the former family compound of Muammar Gaddafi, is also located in the city; Gaddafi largely ruled the country from his residence in this barracks.

Lebanon (ⁱ/ˈlɛbənɒn/ or /ˈlɛbənən/; Arabic: لبنان‎ Libnān or Lubnān, Lebanese Arabic: [lɪbˈneːn]), officially the Lebanese Republic (Arabic: الجمهورية اللبنانية‎ al-Jumhūrīyah al-Libnānīyah, Lebanese Arabic: [elˈʒʊmhuːɾɪjje l.ˈlɪbneːnɪjje]), is a country in the East Mediterranean. It is bordered by Syria to the north and east, and Israel to the south. Lebanon's location at the crossroads of the Mediterranean Basin and the Arabian hinterland has dictated its rich history, and shaped a cultural identity of religious and ethnic diversity.

The earliest evidence of civilization in Lebanon dates back more than 7,000 years—predating recorded history. Lebanon was the home of the Phoenicians, a maritime culture that flourished for nearly 2,500 years (3000–539 BC). Following the collapse of the Ottoman Empire after World War I, the five provinces that comprise modern Lebanon were mandated to France. The French expanded the borders of Mount Lebanon, which was mostly populated by Maronite Catholics and Druze, to include more Muslims. Lebanon gained independence in 1943, and established a unique political system, known as confessionalism, a power-sharing mechanism based on religious communities – Bechara El Khoury who became independent Lebanon's first President and Riad El-Solh, who became Lebanon's first prime minister, are considered the founders of the modern Republic of Lebanon and are national heroes for having led the country's independence. French troops withdrew from Lebanon in 1946.
