Millions of Shiite Pilgrims Gather in Karbala as Iraq Navigates U.S.-Iran Tensions

More than 4.88 million pilgrims have entered Iraq since the start of the Islamic month of Muharram to observe Arbaeen, the 40-day commemoration following Ashoura, which marks the 680 A.D. killing of Imam Hussein and his family at the Battle of Karbala. The annual religious gathering in the holy city drew worshippers from numerous countries this week, cementing its status as one of the world’s largest annual faith-based assemblies.

The pilgrimage unfolded against a backdrop of intensifying geopolitical tensions, with Iraq attempting to maintain its precarious diplomatic balance between Washington and Tehran. Iranian Foreign Minister Abbas Araghchi’s high-profile attendance in Karbala underscored Iran’s continued investment in the religious event, even as regional hostilities threaten further escalation between the United States and Iran.

Observers noted a significant shift in the pilgrimage’s composition this year, with Iranian contingents remaining robust while international attendance from European, Arab, and other Muslim-majority nations declined noticeably. Pilgrims attributed the drop in foreign visitors to regional instability, citing concerns about the ongoing conflict and broader security uncertainties affecting travel decisions.

Iraq’s government continues grappling with competing pressures: economic hardship stemming from oil export disruptions, militia disarmament efforts targeting Iran-backed groups, and the need to prevent deeper involvement in U.S.-Iran hostilities. Kataib Hezbollah, among Iraq’s most influential Iranian-aligned militias, reaffirmed its rejection of disarmament calls during Arbaeen observances, pledging to maintain its armed capacity in the name of resistance.
