Thousands of people gathered in Tehran on Saturday, July 4, 2026, for the start of public funeral ceremonies for Supreme Leader Ali Khamenei [1], [3].

The events mark the death of Iran's highest authority and represent a critical transition for the Islamic Republic's leadership. Authorities said the gathering is the largest funeral in the history of Iran [2].

Official ceremonies are scheduled to last for six days [2]. While thousands of faithful have already arrived at the site [1], [3], Iranian authorities expect total participation to reach between 15 million and 20 million people in Tehran [1], [2].

Ali Khamenei was 86 years old [2]. According to reports from La Nouvelle République, the leader was killed on Feb. 28 during the early stages of a war between Iran and the U.S. [2].

The scale of the event is intended to demonstrate national unity and devotion to the late leader. The massive crowds and prolonged mourning period serve as a state-led effort to solidify the legacy of the Supreme Leader during a period of regional conflict.

The biggest funeral in Iran’s history

The death of Ali Khamenei creates a significant power vacuum in Iran. The scale of these funeral proceedings, projected to involve millions, is a strategic display of legitimacy and stability by the state. By framing the event as a historic national mourning period, the Iranian government aims to maintain internal control and project strength during an active conflict with the U.S.
