18.9 Hezbollah (1982)

Hamas → Sunni Palestinian Islamist movement rooted in Gaza

Hezbollah → Shia Lebanese Islamist movement rooted in Lebanon and tied to Iran

The name Hezbollah means “Party of God.”

Hezbollah was founded in 1982 in Lebanon during the Lebanese Civil War and in response to Israel’s 1982 invasion of Lebanon.

It emerged as a Shia Islamist movement with strong support from Iran, especially through Iran’s Islamic Revolutionary Guard Corps, and it was heavily shaped by the ideology of the 1979 Iranian Revolution. Hezbollah’s early goals included driving Israeli forces out of Lebanon and building a political order more closely aligned with Iran’s revolutionary Islamic model.

Unlike the Muslim Brotherhood, which began primarily as an ideological and social movement, Hezbollah developed much more directly as a politico-militant organization. From an early stage, it combined religion, armed struggle, social services, and political participation. This made Hezbollah, like Hamas, an example of how an Islamist movement can operate simultaneously as a militia, a political actor, and a social-service network.

Hezbollah built support in part through schools, clinics, welfare networks, reconstruction efforts, and aid to families, especially within Lebanon’s Shia population, which had long been underrepresented in Lebanese politics and heavily affected by war and displacement. These networks helped Hezbollah gain legitimacy and loyalty well beyond its armed wing.

At the same time, Hezbollah became known internationally for militancy and terrorism.

In its early years, it was associated with Western hostage-taking and major attacks during the 1980s, including the 1983 bombing of the U.S. Marine barracks in Beirut, which killed 241 U.S. service members. Hezbollah has also carried out rocket attacks, guerrilla warfare, and later military operations against Israel.

Unlike the Sunni transnational jihadist movements Al-Qaeda and ISIS, Hezbollah is a Lebanese Shia Islamist organization rooted in a specific national and sectarian context, with close ties to Iran and a long-term role inside Lebanese politics. It has held seats in Lebanon’s parliament and has remained deeply involved in the country’s internal power structure while maintaining a powerful armed wing.

Hezbollah is also important because it shows how Islamist militancy can become deeply embedded in state and society without fully replacing the state. Rather than becoming Lebanon itself, Hezbollah has operated as a powerful armed and political force inside a weak and divided state.

Instead, it has operated as a powerful armed and political force inside a weak and divided state. That also makes it different from the Taliban, which became the governing authority of Afghanistan, and different from Hamas, which became the de facto ruler of Gaza.

In recent years, Hezbollah’s position has come under greater pressure.

In September 2024, Israel assassinated Hezbollah’s long-time leader Hassan Nasrallah. Naim Qassem has since taken over as Secretary-General. Israel’s 2024 assault significantly eroded Hezbollah’s military power in southern Lebanon, though the group still remained a major political force.

One of the biggest shifts was the fall of Bashar al-Assad in Syria in December 2024. This severed Hezbollah’s main land supply route from Iran, forcing the group to rely more on local production and making it more vulnerable to the current blockade.

After a fragile ceasefire in late 2024, fighting resumed in March 2026, following a U.S.-Israeli military campaign against Iran that killed Iran’s Supreme Leader Ali Khamenei.

In a major shift, Hezbollah is currently facing unprecedented domestic backlash, with the Lebanese government recently moving to outlaw Hezbollah’s military activities, declaring them illegal and calling for the group to place all weapons under state control.

As of April 2026, the Israeli military has launched a ground invasion and currently occupies or maintains control over roughly 50 villages in southern Lebanon. The ongoing 2026 Lebanon War has displaced over one million people (roughly 20% of Lebanon’s population).

Hezbollah represents a Shia politico-militant model of Islamist extremism shaped by the Iranian Revolution, Lebanese civil war, and conflict with Israel. It is not identical to Sunni jihadist groups, but it is a major example of how religion, militancy, social welfare, and political power can be fused into a durable and influential movement.

In section 18.10, we will examine Al-Qaeda (1988), a Sunni jihadist organization that emerged from the Soviet–Afghan War and developed a far more explicitly transnational model of Islamist terrorism.
