President of Lebanon in the context of "National Pact"

The 1958 Lebanon crisis was a political crisis in Lebanon caused by political and religious tensions in the country that included an American military intervention, which lasted for around three months until President Camille Chamoun, who had requested the assistance, completed his term as president of Lebanon. American and Lebanese government forces occupied the Port of Beirut and Beirut International Airport. With the crisis over, the United States withdrew.

Charles Debbas (Arabic: شارل دباس, romanized: Shārl Dabbās; 16 April 1884 – 22 August 1935) was a Greek Orthodox Lebanese political figure. He was the first President of Lebanon (before independence) and served from 1 September 1926 to 2 January 1934, under the French Mandate of Lebanon (known as Greater Lebanon). He also served as the Speaker of the Parliament of Lebanon from January to October 1934.

The 1982 Lebanon War, also called the Second Israeli invasion of Lebanon, began on 6 June 1982, when Israel invaded southern Lebanon. The invasion followed a series of attacks and counter-attacks between the Palestine Liberation Organization (PLO) operating in southern Lebanon and the Israel Defense Forces (IDF), which had caused civilian casualties on both sides of the border. The Israeli military operation, codenamed Operation Peace for Galilee, was launched after gunmen from the Abu Nidal Organization attempted to assassinate Shlomo Argov, Israel's ambassador to the United Kingdom. Israeli prime minister Menachem Begin blamed the PLO, using the incident as a casus belli. It was the second invasion of Lebanon by Israel, following the 1978 South Lebanon conflict.

The Israelis sought to end Palestinian attacks from Lebanon, destroy the Palestine Liberation Organization (PLO) in the country, and install a pro-Israel Maronite Christian government. Israeli forces attacked and overran PLO positions in southern Lebanon and briefly clashed with the Syrian Army, who occupied most of the country's northeast. The Israeli military, together with the South Lebanon Army, seized control of the southern half of Lebanon and laid siege to the capital Beirut. The Lebanese Forces however, despite their clandestine alliance with Israel, refused to participate in the war against the PLO as their leader Bachir Gemayel viewed any direct involvement as assisting an invading army. Surrounded in West Beirut and subjected to heavy Israeli bombardment, the PLO and their allies negotiated a ceasefire with the aid of United States special envoy Philip Habib. The PLO, led by Yasser Arafat, were evacuated from Lebanon, overseen by a multinational peacekeeping force. By expelling the PLO, removing Syrian influence over Lebanon, and installing a pro-Israeli Christian government led by President Bachir Gemayel, the Israeli government hoped to sign a treaty that would give Israel "forty years of peace".

Lebanon is a parliamentary democratic republic within the overall framework of confessionalism, a form of consociationalism in which the highest offices are proportionately reserved for representatives from certain religious communities. The constitution of Lebanon grants the people the right to change their government. However, from the mid-1970s until the parliamentary elections in 1992, the Lebanese Civil War (1975–1990) precluded the exercise of political rights.

According to the constitution, direct elections must be held for the parliament every four years. However, after the parliamentary election in 2009 another election was not held until 2018. The Parliament elects a president every six years to a single term. The president is not eligible for re-election. The last presidential election was in 2025. The president and parliament choose the prime minister.

The Lebanese Parliament (Arabic: مجلس النواب, romanized: Majlis an-Nuwwab, lit. 'House of Representatives') is the unicameral national parliament of the Republic of Lebanon. There are 128 members elected to a four-year term in multi-member constituencies, apportioned among Lebanon's diverse Christian and Muslim denominations but with half of the seats reserved for Christians and half for Muslims per Constitutional Article 24. Lebanon has universal adult suffrage. The parliament's major functions are to elect the President of the republic, to approve the government (although appointed by the President, the Prime Minister, along with the Cabinet, must retain the confidence of a majority in the Parliament), and to approve laws and expenditure.

The Parliament was most recently elected on 15 May 2022. While terms are four years long, parliaments are able to extend the own terms: the parliament elected in June 2009 did so on three separate occasions, delaying the next election until May 2018 while a new electoral law was prepared. According to the Lebanese constitution and the electoral law of 2017, elections are held on a Sunday during the 60 days preceding the end of the sitting parliament's mandate, with the next one due on a Sunday falling between 22 March 2026 and 22 May 2026.
