Compare two parties

Origins. Hezbollah was founded in 1982 amid Israel's Lebanon invasion under direct Iranian patronage; its founding cadres broke from Amal's electoral-nationalist line to pursue armed resistance with Khomeinist ideological alignment. Hamas was founded in December 1987 during the First Intifada by Sheikh Ahmed Yassin and the Gaza branch of the Muslim Brotherhood, whose Egyptian parent organisation predates Hamas by 59 years.

Where they diverge. The deepest cleavage is sectarian doctrine. Hezbollah endorses the Khomeinist wilayat al-faqih doctrine of Iranian clerical leadership — a Shia institutional theology with no equivalent in Sunni jurisprudence. Hamas's 1988 charter and 2017 Document of General Principles draw on Sunni Brotherhood frameworks (Hassan al-Banna, Sayyid Qutb); they would not subordinate Palestinian decision-making to a non-Palestinian cleric. On regional patronage: Hezbollah's relationship with Iran is foundational and institutional (IRGC funding, training, weapons); Hamas's is pragmatic and conditional (significant before the 2011 Syria civil war when Hamas broke with Assad-Iran over Syria's suppression of its Sunni opposition; partially repaired since). On organisational shape: Hezbollah is a unified party-army-social-services apparatus with a clear hierarchy; Hamas has historically maintained a sharper separation between its political bureau (formerly in Damascus, then Doha) and its military Qassam Brigades.

Where they overlap. Both are armed Islamist movements that reject the legitimacy of the Israeli state. Both have governed territory (south Lebanon for Hezbollah; Gaza for Hamas since 2007). Both are designated terrorist organisations by the United States and the EU. Both have lost top leadership to Israeli targeted killings — Mughniyeh, Musawi, Nasrallah, Hashem Safi al-Din (Hezbollah); Sheikh Yassin, Rantissi, Haniyeh, Sinwar (Hamas).

Why it matters today. The "axis of resistance" frame holds in the abstract — both fought Israel after October 7 — but the differential damage tells the story. Hezbollah's top leadership has been decapitated and its arsenal substantially degraded; Hamas's military structure inside Gaza has been heavily attritted but the movement has not surrendered. The axis is materially smaller than it was on 6 October 2023.
