Founded in 1982 by Iran's Revolutionary Guards and classified by the United States and other Western countries as a terrorist organization, Hezbollah (Party of God) is the most powerful group in Lebanon due to a heavily armed militia that fought several wars with Israel. It grew stronger after joining the war in Syria in 2012 in support of Syrian President Bashar al-Assad.
It is both a political movement and guerrilla army, drawing its support from among Lebanon's Shiite population. The group and its allies helped form Lebanon's current government.

Hezbollah's arsenal has been a major point of contention. The group says its arms are needed to deter Israel and, more recently, to guard against Islamist insurgents in Syria.
Hezbollah has been designated a terrorist organization by the US, Canada, Germany, Britain, Argentina, and Honduras as well as the US-allied, mainly Sunni Muslim Gulf Cooperation Council, which includes Saudi Arabia, the United Arab Emirates, Bahrain, and Kuwait. The EU classifies Hezbollah's military wing as a terrorist group, but not its political wing.
Shadowy groups, which Lebanese security officials and Western intelligence say are linked to Hezbollah, launched suicide attacks on Western embassies and targets and kidnapped Westerners in the 1980s. A suicide bombing destroyed the US Marine headquarters and French military barracks in Beirut in 1983, killing 241 US servicemen and 58 French paratroopers. One group, Islamic Jihad, was thought to be led by Imad Mugniyeh, a senior Hezbollah military commander killed – possibly by Israel – in 2008 in Syria.
Argentina blames Hezbollah and Iran for the deadly bombing of a Jewish community center in Buenos Aires in which 85 people died in 1994 and for an attack on the Israeli embassy in Buenos Aires in 1992 that killed 29 people. Both deny any responsibility.
Bulgaria accuses Hezbollah of carrying out a bomb attack that killed five Israeli tourists in the Black Sea city of Burgas in 2012.
