In Karbala, the world's largest Shia pilgrimage, over 20 million faithful

Karbala, a holy city in southern Iraq, hosted this week one of the largest human gatherings on the planet: more than 20 million Shia Muslim pilgrims gathered for the annual commemoration of the killing, in the seventh century, of a central figure of their faith. The figure and details of the account come from a report from the field, the only source gathered for this news item: no independent confirmation is currently available.

This year, according to the report, Iranian participation in the pilgrimage was higher than usual. Iran is a Shia-majority country, and many of the pilgrims interviewed linked the increase in participation to the death of their contemporary religious leader, Ayatollah Ali Khamenei, killed by airstrikes in the early stages of the war between the United States and Israel against Iran. The link between religious and political mourning and the record influx of Iranian faithful describes a community that has also turned this year’s pilgrimage into an act of collective remembrance tied to the events of the war in recent months.

The scale of the event — tens of millions of people converging on a single city over a few days — places Karbala among the largest recurring human gatherings in the world, a figure that alone would normally require multiple independent sources to be treated with absolute statistical certainty. In this case, the figure comes from a single report, and Redazione Zero reports it with due caution: not an official figure certified by an Iraqi or international body, but the estimate of a news outlet with correspondents on the ground.

No information emerges, in the materials gathered, about any security incidents linked to the record influx of pilgrims, nor official figures provided by Iraqi authorities on the exact number of attendees. The commemoration, which is repeated every year in the holy city, remains one of the largest mass religious events in the world, and this year takes on an additional significance for the Iranian Shia community, marked by the loss of its religious leader in the preceding months.

It remains to be seen, in the coming days, whether other international outlets will confirm the figure of 20 million attendees or provide alternative estimates, an element that would allow this newsroom to consolidate the story with a second independent source.
