National crisis (2019–present)
On 17 October 2019, the first of a series of mass civil demonstrations erupted; they were initially triggered by planned taxes on gasoline, tobacco and online phone calls such as through WhatsApp, but quickly expanded into a country-wide condemnation of sectarian rule, a stagnant economy and liquidity crisis, unemployment, endemic corruption in the public sector, legislation (such as banking secrecy) that is perceived to shield the ruling class from accountability and failures from the government to provide basic services such as electricity, water and sanitation.
As a result of the protests, Lebanon entered a political crisis, with Prime Minister Saad Hariri tendering his resignation and echoing protestors' demands for a government of independent specialists. Other politicians targeted by the protests have remained in power. On 19 December 2019, former Minister of Education Hassan Diab was designated the next prime minister and tasked with forming a new cabinet. Protests and acts of civil disobedience continued, with protesters denouncing and condemning the designation of Diab as prime minister. By July 2020, Lebanon was suffering the worst economic crisis in decades. Lebanon was the first country in the Middle East and North Africa to see its inflation rate exceed 50% for 30 consecutive days, according to Steve H. Hanke, professor of applied economics at the Johns Hopkins University.
On 4 August 2020, an explosion at the port of Beirut, Lebanon's main port, destroyed the surrounding areas, killing over 200 people, and injuring thousands more. The cause of the explosion was later determined to be 2,750 tonnes of ammonium nitrate that had been unsafely stored, and accidentally set on fire that Tuesday afternoon. Protests resumed within days following the explosion, which resulted in the resignation of Prime Minister Hassan Diab and his cabinet on 10 August 2020, nonetheless continuing to stay in office in a caretaker capacity. Demonstrations continued into 2021 with Lebanese blocking the roads with burned tires protesting against the poverty and the economic crisis.
On 11 March 2021 the caretaker minister of energy Raymond Ghajar warned that Lebanon was threatened with "total darkness" at the end of March if no money was secured to buy fuel for power stations. In August 2021, a large fuel explosion in northern Lebanon killed 28 people. September saw the formation of a new cabinet led by former prime minister Najib Mikati. On 9 October 2021, the entire nation lost power for 24 hours after its two main power stations ran out of power due to the currency and fuel shortage. Days later, sectarian violence in Beirut killed a number of people in the deadliest clashes in the country since 2008. By January 2022, BBC News reported that the crisis in Lebanon had deepened further, with the value of the Lebanese pound plummeting and a scheduled general election expected to be delayed indefinitely. The postponement of parliamentary elections was said to prolong the political deadlock in the country. The European Parliament called Lebanon's present situation a 'man-made disaster caused by a handful of men across the political class'.
In May 2022, Lebanon held its first election since a painful economic crisis dragged it to the brink of becoming a failed state. Lebanon's crisis has been so severe that more than 80 percent of the population is now considered poor by the United Nations. In the election the Shia Muslim Hezbollah movement (and its allies) lost their parliamentary majority. Hezbollah did not lose any of its seats, but its allies lost seats. Hezbollah's ally, President Michel Aoun's Free Patriotic Movement, was no longer the biggest Christian party after the election. A rival Christian party, the Lebanese Forces led by Samir Geagea, became the largest Christian-based party in parliament. The Sunni Future Movement, led by former prime minister Saad Hariri, did not participate in the election, leaving a political vacuum for other Sunni politicians to fill. The Lebanese crisis became so severe that multiple boats left the coast holding migrants in a desperate run from the country. Many proved unsuccessful and fatal. In April 2022, 6 people died and around 50 people were rescued after an overloaded boat sunk in Tripoli. On 22 September, at least 94 people were killed when a boat carrying migrants from Lebanon capsized off Syria's coast. 9 people survived. Many were declared missing and some were found either dead or injured. Dead bodies were sent to nearby hospitals. 40 people remained missing as of 24 September.
On 1 February 2023, the central bank of Lebanon devalued the Lebanese pound by 90% amid the ongoing financial crisis. This was the first time Lebanon had devalued its official exchange rate in 25 years. As of 2023, Lebanon is considered to have become a failed state, suffering from chronic poverty, economic mismanagement and a banking collapse.
The Gaza war sparked a renewed Israel–Hezbollah conflict. In 2024, Hezbollah said it would not stop attacking Israel until Israel ceases its attacks in Gaza. Starting with the Israeli explosion of Lebanese pagers and walkie talkies in September 2024, the conflict escalated severely, with the 23 September 2024 Israeli airstrikes on Lebanon killing at least 558 people, and sparking a mass exodus from southern Lebanon. On 27 September 2024, Hezbollah leader Hassan Nasrallah was killed in an Israeli airstrike. On 1 October 2024, Lebanon was invaded by Israel with the objective of destroying infrastructure belonging to Hezbollah in the south of the country. In November 2024, a ceasefire deal was signed between Israel and the Lebanese armed group Hezbollah to end 13 months of conflict. According to the agreement, Hezbollah was given 60 days to end its armed presence in southern Lebanon and Israeli forces were obliged to withdraw from the area over the same period.
The fall of Assad's Baathist regime in Syria was another blow to its Lebanese ally, Hezbollah, which was already weakened because of Israeli military actions. An analysis by the United States Institute of Peace reported on a sense that the Syrian regime change in December 2024 started a new chapter in Lebanese politics.
In January 2025, Joseph Aoun, the Lebanese army commander, was elected Lebanese 14th president after a two-year vacancy. In February 2025, Prime Minister Nawaf Salam, former president of the International Court of Justice (ICJ), formed a new government of 24 ministers after two-year caretaker cabinet. On 26 February 2025, Lebanon's government of Nawaf Salam won a confidence vote in parliament.
Since 2 March 2026, intensified Israeli attacks across Lebanon have killed over 1,000 people and displaced nearly 1 million, representing approximately 20% of the country's population. On 24 March, Israeli Defence Minister Israel Katz announced plans to establish a "defensive buffer zone" by occupying southern Lebanon up to the Litani River. This plan was expanded on 31 March, when Katz stated that residential structures in border villages would be demolished to prevent the return of approximately 600,000 displaced residents.
