A group of Iranian opposition supporters is gearing up for what might be the most politically charged moment of the 2026 FIFA World Cup, and it has nothing to do with what happens on the pitch.

Activist Arezu Rashidi has announced that Iranian fans intend to enter World Cup stadiums carrying the Lion and Sun flag, the pre-revolution emblem that represented Iran for over seven decades before the 1979 Islamic Revolution. The problem: FIFA has explicitly banned the flag from tournament venues.

A flag with a long memory

The Lion and Sun flag served as Iran’s national standard from 1907 until the revolution that brought the Islamic Republic to power. After 1979, the new government replaced it with the current flag featuring a stylized Allah emblem.

Within the diaspora and among domestic opposition groups, the older flag has evolved into a symbol of non-partisan identity and defiance against the ruling government. FIFA’s decision to restrict this emblem during the 2026 tournament has reignited debates reminiscent of those that arose during the 2022 World Cup, when attempts to display the Lion and Sun flag sparked protests and ignited social media campaigns that drew global attention to the Iranian diaspora’s grievances with the regime back home.

That tournament coincided with the massive protest movement inside Iran following the death of Mahsa Amini, which meant every Iranian match carried the weight of a country’s struggle for basic freedoms.

The enforcement problem

Supporters have already demonstrated their ability to get the flag into venues. Reports indicate that the Lion and Sun flag was successfully unfurled at Levi’s Stadium, one of the 2026 World Cup host venues, signaling that FIFA’s enforcement mechanisms may not be up to the task.

Rashidi’s public announcement of the plan adds another layer of complexity for FIFA. When defiance is organized and publicized in advance, the governing body faces an uncomfortable choice: crack down visibly on fans carrying a historical national symbol, or look the other way and effectively admit the ban is unenforceable.

What this means beyond the stadium

The 2026 tournament is taking place against a backdrop of ongoing demonstrations inside Iran linked to the World Cup itself. There’s also been reporting about an alleged IRGC-linked cryptocurrency program intended for select World Cup spectators, a detail that underscores how seriously Tehran takes the optics of this tournament.

The 2026 World Cup kicks off in the US, Canada, and Mexico this month.
