Lebanon covers 10,452 square kilometres on the eastern Mediterranean shore of the Levant in West Asia, a narrow state bordered by Syria to the north and east, Israel to the south, and roughly 225 kilometres of coastline to the west. Beirut, the capital, lies on the densely urbanized central coast. Behind the discontinuous coastal plain, the land rises abruptly into the Mount Lebanon range, whose highest summit, Qurnat as Sawda’, reaches about 3,088 metres. East of that ridge lies the long, fertile Beqaa Valley, part of the larger Levantine rift system, and beyond it the Anti-Lebanon Mountains, which form much of the frontier with Syria and culminate regionally around Mount Hermon. This compressed sequence of sea, mountains, basin and eastern highlands produces sharp variations in climate, vegetation, agriculture and settlement.
Lebanon has a Mediterranean climate modified strongly by elevation and rain-shadow effects, so conditions on the coast, Mount Lebanon and the interior differ substantially. Most precipitation falls between late autumn and early spring; coastal districts commonly receive about 700–1,000 millimetres annually, while the Beqaa is markedly drier, often around 200–450 millimetres in its drier sectors. The western mountain slopes intercept moist Mediterranean air and receive heavier rain and substantial winter snow, whereas the eastern side is more continental, with colder winters, hotter summer days and lower rainfall. Dry summers make groundwater, springs, reservoirs and snowmelt important to agriculture and urban supply. Recent national climate assessments emphasize rising temperatures, more erratic rainfall and greater drought stress, with consequences for crop yields, forest-fire risk and water availability. The coast also faces erosion, marine pollution and increasing exposure to sea-level rise, while intense winter storms can produce flash flooding in heavily urbanized drainage basins.
These climatic gradients support Mediterranean maquis, oak and pine woodland, remnant cedar and fir forests, high-elevation grasslands, river valleys, wetlands and coastal ecosystems within a remarkably small territory. World Bank data put forest area at 14.2% of land in 2023, though broader definitions that include scrub and other wooded land produce higher totals. Cedar stands survive in protected mountain landscapes such as the Shouf Cedar Nature Reserve, Horsh Ehden and the Cedars of God near Bsharri, the latter forming part of a UNESCO World Heritage property with the Qadisha Valley. Farming is concentrated in the Beqaa, Akkar plain, coastal lowlands and terraced mountain slopes; potatoes, vegetables, grapes, apples, olives and citrus are characteristic crops. The Litani River, entirely within Lebanon, is central to irrigation and hydropower and feeds Lake Qaraoun, while the Orontes and Hasbani connect Lebanon hydrologically to wider regional basins. Urban expansion, quarrying, wildfire, overgrazing and fragmented land management continue to pressure habitats and agricultural soils.
Human settlement in the territory reaches deep into prehistory, and Byblos preserves evidence of occupation from the Neolithic period onward. During the Bronze and Iron Ages, the coast became a core zone of Phoenician urban civilization, organized around maritime city-states including Byblos, Sidon and Tyre rather than a unified “Lebanese” kingdom in the modern sense. Their merchants tied the Levant to Cyprus, Egypt, North Africa and the western Mediterranean, while Phoenician writing systems played an important part in the history of alphabetic scripts. The region later passed through Assyrian, Babylonian, Persian, Hellenistic and Roman rule; Baalbek, known as Heliopolis in the Hellenistic and Roman periods, became a major religious centre whose monumental temples remain among the country’s most important archaeological sites. Christianity spread under Roman and Byzantine rule, and Arab-Muslim conquest in the seventh century incorporated the area into successive caliphates. Crusader, Ayyubid and Mamluk struggles later reshaped the coast and interior before the Ottoman Empire took control in 1516, governing the area through local elites and changing administrative arrangements.
Under Ottoman rule, Mount Lebanon developed political structures distinct from the neighboring coastal cities and Syrian interior, with Druze and Maronite communities becoming especially influential in the mountain. Nineteenth-century sectarian violence, including the conflict of 1860, prompted international intervention and the creation of the autonomous Mount Lebanon Mutasarrifate in 1861. After the Ottoman collapse, France proclaimed Greater Lebanon in 1920, joining Mount Lebanon to Beirut, the Beqaa, the north and the south; these boundaries largely created the territorial framework of the modern republic. A constitution followed in 1926, and independence was secured politically in 1943, with French forces leaving in 1946. The unwritten National Pact institutionalized confessional power-sharing, but demographic change, Palestinian displacement, regional rivalries and armed movements contributed to the 1975–1990 civil war, which drew in Syria, Israel and the Palestine Liberation Organization. The 1989 Taif Agreement rebalanced constitutional authority and parliamentary representation. Syrian forces withdrew in 2005; later crises included the 2006 Israel-Hezbollah war, the 2019 financial collapse, the 2020 Beirut port explosion and destructive conflict in 2023–2024. The election of a president in January 2025 ended a prolonged institutional vacancy, but political stabilization remained closely tied to security and economic reform.
Lebanon’s economy remains defined by the financial crisis that began in 2019, when a banking model dependent on capital inflows and large public borrowing became unsustainable. The sovereign default of 2020, severe currency depreciation, restrictions on bank deposits and widespread dollarization sharply reduced household purchasing power and formal credit. Conflict then caused real GDP to contract by 7.1% in 2024, taking the cumulative decline since 2019 to nearly 40%; the World Bank estimated a 3.5% rebound in 2025, driven mainly by consumption, remittances, tourism, real estate and construction. Services dominate activity, while manufacturing, food processing, agriculture and trade provide important employment and exports. Remittances were equivalent to about one-third of GDP in 2023, illustrating the economic weight of the diaspora. Merchandise trade is structurally import-heavy: in 2023 exports totaled about US$4.6 billion against imports of US$18.1 billion, with the United Arab Emirates the leading export market and China the largest import source. Reconstruction, banking reform and restored public investment remain central development constraints.
Lebanon has not conducted a full population census since 1932, so contemporary totals are estimates rather than census counts and sectarian population shares should be treated cautiously. World Bank and UN data place the 2025 population at about 5.85 million, with roughly nine in ten residents living in urban areas. Settlement is heavily concentrated along the coastal belt and the western slopes of Mount Lebanon, especially in the continuous metropolitan zone around Beirut and its suburbs; Tripoli anchors the north, while Sidon and Tyre are principal southern coastal centres and Zahle and Baalbek are major inland cities. This pattern reflects the narrow coastal plain, concentrated employment and services, and the transport advantages of the Mediterranean corridor. Administratively, the country is divided into eight governorates: Beirut, Mount Lebanon, North Lebanon, Akkar, Beqaa, Baalbek-Hermel, South Lebanon and Nabatiyeh. Lebanon also hosts large refugee populations; the government estimated about 1.3 million Syrians in mid-2025, alongside long-established Palestinian communities, substantially affecting housing, schools, labor markets and public services.
Arabic is Lebanon’s official language, while Lebanese Arabic is the predominant spoken vernacular; French and English are widely used in education, business and media, and Armenian remains important within Armenian communities. Religious affiliation is institutionally significant because the political and personal-status systems recognize 18 religious groups, including Sunni and Shia Muslims, Druze, Maronite Catholics, Greek Orthodox, Melkite Greek Catholics, Armenian Apostolics and other Christian communities. Reliable current sectarian percentages are unavailable because no modern census has enumerated the population by religion. Cultural life reflects interaction among Arabic, Mediterranean, Ottoman and European intellectual networks rather than a single communal tradition. Beirut became a major centre of Arabic publishing, journalism and higher education in the nineteenth and twentieth centuries, associated with institutions such as the American University of Beirut and Saint Joseph University. Lebanese literature and music have also circulated widely through the Arab world and the diaspora, while architecture ranges from medieval religious buildings and Ottoman urban fabric to mandate-era planning and postwar reconstruction.
Road transport carries most domestic passenger and freight movement because Lebanon’s railway system is not in regular operation. The main north-south axis follows the densely settled coast through Tripoli, Beirut and the southern cities, while routes across Mount Lebanon connect the capital to Zahle, the Beqaa and the Syrian frontier, making topography a persistent source of congestion and high construction costs. Beirut and Tripoli are the principal commercial ports; the Port of Beirut remains a national trade gateway despite the destruction caused by the August 2020 explosion and continuing governance and reconstruction needs. Beirut-Rafic Hariri International Airport is the country’s main international aviation hub. Electricity presents a sharper infrastructure constraint: Électricité du Liban operates the public grid and thermal and hydropower assets, but supply has long been unreliable, prompting extensive reliance on private generators and, increasingly, distributed solar systems. Digital connectivity is much stronger by comparison, with ITU data showing 80.6% of individuals using the internet in 2024, although service quality and affordability vary.
Lebanon’s regional importance derives less from its size than from its position between the eastern Mediterranean, Syria and the wider Arab hinterland, its large diaspora networks, and the political significance of its southern border with Israel. It is a founding member of both the United Nations and the Arab League, while UN Security Council Resolution 1701 and the UN Interim Force in Lebanon remain central to efforts to manage security along the Blue Line; renewed hostilities in 2026 have underlined how fragile that framework remains. The same geography that supported commerce also exposes the country to regional wars, refugee movements and disruptions of overland trade. Medium-term recovery therefore depends on several linked tasks: stabilizing the security environment, rebuilding conflict-damaged housing and infrastructure, restructuring banks and public debt, restoring reliable electricity and water services, and strengthening institutions capable of managing investment across sectarian and regional divides. Climate stress and high urban concentration add further pressure. Lebanon’s future weight in the Levant will depend largely on whether its commercial, human and geographic assets can again operate through a functioning state rather than compensate for its weaknesses.
