Hundreds of thousands of mourners [1] gathered at the Imam Khomeini Grand Mosalla in central Tehran to attend the state funeral of Supreme Leader Ali Khamenei.

The event signals the Iranian regime's intent to maintain ideological continuity and project strength during a leadership transition. By framing the death within a narrative of martyrdom and vengeance, the state is leveraging a moment of national mourning to consolidate domestic support and warn foreign adversaries.

Funeral ceremonies began on Saturday and are expected to last at least one week [2]. To encourage maximum public attendance, the Iranian government shut down the country for two days on Sunday and Monday [3].

Attendees carried massive red flags bearing the slogan "Ya Latharat al‑Khamenei," which translates to "O Avengers of Khamenei" [1, 2]. These red flags are traditional symbols of revenge in the region. Throughout the gathering, roaring chants calling for vengeance against perceived enemies echoed across the capital [1].

Organizers linked the death of the late Supreme Leader to the martyrdom of Imam Hussein [2]. This religious framing serves to justify the calls for hostility toward the U.S. and Israel [2]. The display of red flags and the nature of the chants are intended to signal that the regime's foreign policy, and its commitment to confrontation, will remain unchanged despite the loss of its leader [2].

The atmosphere in Tehran remained charged as mourners filled the prayer grounds, reinforcing the state's message of continuity through a public demonstration of grief and aggression [1].

The use of 'revenge flags' and the explicit calls for vengeance at the state funeral indicate that Iran is not seeking a period of diplomatic cooling following the death of Ali Khamenei. Instead, the regime is utilizing the funeral as a political tool to ensure the next leadership phase begins with a mandate for aggression and ideological purity, specifically targeting the U.S. and Israel to prevent any perception of weakness during the transition.
