Persian Gulf National Day
April 30, Wednesday

Historical context
The holiday was established in memory of an important historical event — the expulsion of the Portuguese from Hormuz in 1622 during the reign of Shah Abbas I, one of the outstanding rulers of the Safavid dynasty. This event became a symbol of national independence and the struggle for control over a strategically important region.
Significance of the holiday
National Persian Gulf Day highlights the historical and cultural significance of the Persian Gulf for Iran and draws attention to the country's right to use this specific name — "Persian Gulf", as opposed to alternative versions promoted by international organizations and some neighboring states.
Main forms of celebration
- Holding official ceremonies and events in coastal cities
- Decorating buildings with national flags and banners labeled “Persian Gulf”
- Organizing academic conferences dedicated to the region’s history
- Publishing articles and TV programs reinforcing Iranian national identity
- Educational activities in schools and universities
Modern significance
The holiday also has a diplomatic aspect: it serves as a cultural and political response to disputes over the name of the gulf. Iran actively promotes the use of the term “Persian Gulf” in international documents and geographical sources.
