A Shia Cause and a Security Charge: Azerbaijan's Hijab Decree Revives Tehran's "Israeli Base" Narrative

Azerbaijan’s ban on headscarves in state schools has revived Tehran’s long-standing charge that Baku serves as an Israeli base against Iran, and it has given that charge a religious edge. The decree, issued on September 21, has kept girls and teachers who wear the hijab out of classrooms and set off student boycotts and street protests in a majority-Shia country. Within three weeks the dispute reached Iranian front pages. Senior clerics in Qom and Tabriz framed the ban as an attack on Shia identity, and the hardline daily Kayhan recast it as an Israeli project. The Iranian government, by contrast, has avoided escalation. We assess that religious and anti-Israel rhetoric will grow while Tehran avoids a rupture with Baku, because the U.S. blockade makes the land routes through the Caucasus more valuable to Iran than at any point since the war began.

An Old Accusation Finds a New Occasion

The decree did not create Tehran’s claim that Azerbaijan hosts Israeli military and intelligence assets. That claim has resurfaced at every moment of bilateral tension for years. In October 2021 the Iranian army held the Fatehan-e Kheybar exercise on the Azerbaijani border, and Iranian outlets presented it as a warning against Baku’s “adventurism.” In March 2023 the Iranian press treated Azerbaijan’s new embassy in Tel Aviv as a milestone in the alliance between the two countries.

The war sharpened the charge. During the 12-day war of June 2025, Iranian outlets such as Tabnak and Mashregh examined claims that Israeli drones and aircraft used Azerbaijani airspace, while also reporting President Ilham Aliyev’s denials. In March 2026, after a drone struck the Azerbaijani exclave of Nakhchivan, Iran’s General Staff denied launching it. In June 2026, Kayhan reported that Israel had sent forces to Azerbaijan during the war. The accusation was already in place. The hijab decree supplied the occasion to revive it, and between October 14 and 17 Kayhan’s language moved from describing the ban as an Israeli order to Aliyev to calling Baku Israel’s main base against Iran.

The Religious Track: A Shia Cause

Iranian coverage presents the decree as a state campaign against the faith of a Shia-majority population. The Mehr news agency reported the ban and the protests that followed and attributed the policy to state secularism and foreign pressure. The religious establishment responded quickly. Ayatollah Mohammad Javad Fazel Lankarani, a senior jurist in Qom, said the ban defied “an explicit ruling of the Quran,” urged protesters to continue and asked Iranian officials to respond. He also warned Baku about the fate of rulers who opposed religion. The Tabriz seminary and the management center of Qom’s women’s seminaries issued their own condemnations, and the World Assembly of Shia Studies called the policy religious apartheid. On October 17, Qods carried Ayatollah Abolqasem Alidoust’s warning that the restrictions repeat failed historical experiments, and Jomhouri-ye Eslami ran a column offering friendly advice to Aliyev.

The clerical response draws heavily on Iran’s own history. For Iranian clerics, a secular ruler removing the veil from schoolgirls recalls Reza Shah’s unveiling decree of 1936, the founding grievance of clerical opposition to the Pahlavi monarchy. Seen through that lens, Baku’s decree becomes a test of the Islamic Republic’s claim to protect Shia communities beyond its borders. That includes the Shia of the Caucasus, who share language and kinship ties with Iran’s own Azerbaijani population.

Iranian media also amplified Sunni and pan-Islamic voices, which allows Tehran to present the dispute as a concern of the entire Muslim world. Outlets carried appeals from the Doha-based International Union of Muslim Scholars and the Palestinian Scholars Council, along with condemnations from Sunni clerics inside Iran. Turkey’s reaction received close attention. Iranian outlets reported protests outside Azerbaijan’s consulate in Istanbul, criticism from an adviser to President Erdoğan and a sharp reply from Aliyev’s New Azerbaijan Party telling Ankara to respect Azerbaijan’s internal affairs. From Tehran’s perspective, any rift between Baku and its closest ally is a welcome side effect. A Hamshahri headline asking how Iran should react to the protests indicates that the question remains open within the establishment.

Kayhan’s Domestic Mirror

Kayhan’s campaign is closely tied to the hijab fight inside Iran. On September 25, before the Azerbaijani protests spread, editor Hossein Shariatmadari published an open appeal to the heads of Iran’s three branches of government over hijab enforcement. Other outlets summarized it as calling official laxity on hijab a form of cooperation with the enemy. Kayhan then carried that argument across the border. On October 14 it asked why reformists issue statements about Afghan women while staying silent about veiled Azerbaijani girls. It later argued that Deputy Foreign Minister Kazem Gharibabadi should not have traveled to Baku at all, both because Israel’s president would be present and because of the hijab ban. For Kayhan, Baku serves as a ready illustration of where a retreat on hijab leads, and as a weapon against the government and its reformist allies.

The Security Track: Israel in Baku

Kayhan moved quickly from religion to geopolitics. On October 14 it wrote that the people of Azerbaijan regard the unveiling order as an Israeli directive to Aliyev. A day earlier its columnist Mohsen Pakaein, a former diplomat, had argued that the decree itself caused the protests, with no Iranian or Turkish interference, and that many analysts see Israel behind the scenes.

Israeli President Isaac Herzog’s visit then gave the narrative a focal point. Iranian outlets reported that he flew to Baku on an Azerbaijani aircraft to avoid Turkish airspace restrictions. When he addressed the summit of the Conference on Interaction and Confidence-Building Measures in Asia (CICA) on October 15, Iran’s delegation and those of 12 other states left the hall, according to Tasnim. Gharibabadi then called for Israel’s expulsion from the forum. Ali Akbar Velayati, the Leader’s senior foreign policy adviser, contrasted Turkey’s walkout with Baku’s hospitality and questioned whether Azerbaijan is fit to host a summit of the Organization of Islamic Cooperation (OIC).

On October 17, Kayhan gave the theme front-page treatment. Caucasus analyst Ehsan Movahedian called Baku Israel’s main base against Iran and accused Aliyev of seeking to erase the identity of Azerbaijan’s people. Jam-e Jam ran a Pakaein piece on what it called Israel’s humiliation in Baku. The two tracks now form a single argument. In this telling, the veil ban is cultural warfare, Israel directs it, and the same Israel uses Azerbaijani territory against Iran. The October 15 Iranian Press Monitor noted how quickly earlier claims of Israeli authorship collapsed, and the October 17 edition tracked the shift in coverage toward Israel’s diplomatic presence in the Caucasus.

Why the Fusion Matters, and What It Costs

Joining the two tracks serves several purposes for the Islamic Republic. It turns a dispute over school uniforms into apparent proof of a hostile Israeli design on Iran’s northern border, a claim that Iranian audiences already accept after two wars. It gives the clerical establishment a cause in which it speaks for Shia communities abroad at a time when the state is absorbed by the war and the blockade. It also hands Kayhan a fresh argument at home: a secular ruler aligned with Israel is unveiling schoolgirls, so any softening on hijab inside Iran serves the same enemy.

The narrative also carries costs. Azerbaijan borders Iran’s Azerbaijani provinces, and Baku has long accused Tehran of using religion to reach its Shia population. Loud clerical involvement from Iran feeds that charge, as an Azerbaijani body’s recent accusation that Iran was stirring the protests shows. Tehran’s own record also weakens its case abroad, since Iranian law requires women to wear the hijab. In addition, the louder the claim that Baku is an Israeli base, the harder it becomes for Iranian diplomats to maintain working relations with a neighbor Iran needs for trade and transit. The same Caucasus coverage surfaced in our October 15 special on antisemitic themes in Iranian state media.

The State Holds Back

Official Iran has avoided the escalatory language of the clerics and Kayhan. When the Azerbaijani body accused Tehran of stirring the protests, Iran’s embassy in Baku rejected accusations over educational matters and called for avoiding tension in bilateral relations. The Foreign Ministry kept Gharibabadi at the CICA table until Herzog spoke and limited its protest to the walkout and the call for Israel’s expulsion.

Interest explains this restraint. The U.S. blockade has closed Iran’s sea trade, which raises the value of the land routes north through the Caucasus to Russia. It also raises the stakes of corridor politics around Armenia, where Tehran is already uneasy about the U.S.-backed TRIPP route. Russian Foreign Minister Sergei Lavrov is due in Tehran on October 19, after a Russia-GCC meeting in Manama. A rupture with Baku would cost Iran routes and partners it needs now. The government is therefore letting the clerics and the press carry the Shia cause while it keeps its channel to Aliyev open.

Key Points

The hijab decree has revived an old accusation and given it religious force. Iran’s charge that Azerbaijan hosts Israeli assets predates the decree by years, but the ban has fused it with a Shia grievance that clerics and the hardline press can mobilize (high confidence).
Clerics and the hardline press are leading the campaign, while the state holds back. Seminaries in Qom and Tabriz and the Kayhan newspaper drive the escalation, while the embassy in Baku and the Foreign Ministry work to contain it (high confidence).
Kayhan is using Baku as a weapon in Iran’s domestic hijab fight. Its coverage links the Azerbaijani decree to Shariatmadari’s attacks on official laxity at home and to criticism of reformists and the Foreign Ministry (moderate confidence).
The most likely path is rhetorical escalation without a material break. The blockade makes Caucasus land routes and the Russia channel more valuable to Tehran, which gives the government strong reasons to avoid a rupture with Baku (moderate confidence).
The narrative carries real risks for Tehran. Visible clerical involvement reinforces Baku’s long-standing charge that Iran uses religion to reach Azerbaijan’s Shia, and Iran’s own hijab laws undercut its case abroad (moderate confidence).

What to Watch

Clerical mobilization. Statements by senior clerics in Qom, or by Friday prayer leaders in Tabriz and Ardabil, calling for action or demonstrations. A call that mobilizes Iranian Azerbaijanis would move the dispute beyond rhetoric.
The protests in Azerbaijan. Arrests and court cases against hijab protesters, and how Iranian state media cover them.
Factional pressure in Tehran. Further Kayhan attacks on the Foreign Ministry or reformists over Baku, and any official Foreign Ministry comment on the decree itself.
Border and airspace incidents. Iranian claims of Israeli use of Azerbaijani airspace or territory, or incidents near Nakhchivan or the Aras River border.
Diplomatic signals. Iranian moves against Baku’s role as an OIC summit host, any further high-level Israeli visit to Azerbaijan, and the tone of Lavrov’s visit on Caucasus routes and TRIPP.
