Hezbollah [Arab., = Party of God], Lebanese Shiite political party and militia. Founded in 1982 with Iranian help to oppose Israeli forces occupying S Lebanon, Hezbollah launched guerrilla attacks and suicide bombings against Israeli forces (which were a factor in Israel's withdrawal in 2000), and mounted terror attacks on other targets inside and outside Lebanon, include the 1983 bombing of a U.S. Marine barracks in Beirut. With strong support among religious, comparatively poor Shiites in S Lebanon the Biqa (Bekaa) valley, and Beirut's southern suburbs, and underwritten financially by Iran and individual Shiites, Hezbollah established a Shiite social-services network, including schools, hospitals, and clinics, and emerged as a major Lebanese political force; it has been led since 1992 by Hassan Nasrallah, a charismatic Shiite cleric. Supported militarily by Iran and Syria, Hezbollah's fighters used the years after Israel's withdrawal to retrain and rearm, acquiring large numbers of missiles and sophisticated equipment.
Politically part of the pro-Syrian camp in Lebanon, the party nonetheless became part of the largely anti-Syrian government established in 2005, and resisted the government's and the United Nations' call that it disarm. In 2006 a cross-border Hezbollah attack on Israeli soldiers, in which two Israelis were captured, sparked warfare (July–August) between Hezbollah militia and Israeli forces in which Hezbollah launched hundreds of missiles at Israel (many at civilian targets) and maintained a stubborn resistance against the Israeli forces that invaded S Lebanon.
Hezbollah emerged from the fighting, which it regarded as a victory, determined to claim a larger political voice in the Lebanese government, and ulitmately forced (2008) the goverment to give it and its allies veto power in the cabinet. In the 2009 elections its coalition placed second, with 45% of the vote, and subsequently again served in a national unity government. Denouncing a joint UN-Lebanon investigation into Prime Minister Rafik Hariri's assassination, which ultimately indicted four Hezbollah members, the party and its allies withdrew from the government in 2011; they were part of a new government formed in July. Hezbollah has provided training and other support, including fighters, to Syrian government forces in the Syrian civil war.
