Circassian Flag Day - 25 April:

Iyad Youghar and Zeynel Besleney speak about the origins of the Circassian flag at the University of Warsaw in November 2022.

NOTE: Correction! from time 3:50.
"It was not David Urquhart, who delivered the Circassian flag to the Circassians.
James Bell, who travelled with John Longworth, onboard Vixen to the Circassian coast, was requested to hand it over upon arrival to the Circassians."
(After a period of time, he bade farewell to James Bell and Longworth who traveled to the Caucasus on board the steamer Vixen. After his arrival, Bill handed over a package to Nour Mohammad Haghur, saying that Prince Zan Seferbi had requested for it to be delivered to him. The package turned out to contain a piece of green silk material, embroidered in gold thread twelve gold stars and three crossed arrows. Nour Mohammad was surprised and wondered, “What is this? Is it what I think?” Bill answered, “Yes, you are right, but I do not want anyone to know that I am who brought it to you.”)
