"Before other peoples arrived on the coasts of this sea, Iranians have been living here for thousands of years and have founded a long-time civilization on the Persian Gulf coasts that have attracted other nations," Salehi said in a message.
He added, "The Persian Gulf region is the birthplace of human beings who have a long history in the border, maritime and trade."
On April 30, 2019, Iranian Foreign Minister Mohammad Javad Zarif, in a video post on his Instagram page, joined the nation in commemorating the National Persian Gulf Day, highlighting the significance of the strategic body of water as a “lifeline” for the country.
Zarif posted a video on his Instagram page to honor the National Persian Gulf Day, which has been annually celebrated in Iran since 2005.
Every year, Iranians commemorate the Persian Gulf on the 10th day of Ordibehesht, the second month on the Iranian calendar, which usually falls on April 30 but this year it has fallen on April 29 due to the leap year.
The date coincides with the anniversary of a successful military campaign by Shah Abbas I of Persia (the old name for Iran) in 1622, which drove the Portuguese navy out of the Strait of Hormuz, a waterway which separates the Persian Gulf from the Gulf of Oman.
The national occasion is meant to stress the fact that the inland sea has been referred to by historians and ancient texts as Persian since the Achaemenid Empire was established in what is now modern day Iran.
