500th anniversary of the Zaporozhian Sich

The 500th anniversary of the Zaporozhian Sich (Ukrainian: 500-ліття Запорозького козацтва, romanized: 500-littia Zaporozkoho kozatstva) was a group of celebrations organised by the Taras Shevchenko Society for the Ukrainian Language [uk] and People's Movement of Ukraine and held in August 1990 to commemorate the 500th anniversary of the founding of the Zaporozhian Sich.

Celebrations on that day commemorated Ukrainian historian Dmytro Yavornytsky, who had studied the Zaporozhian Sich.

This was followed the next day by a convocation of Cossacks from throughout Ukraine (including the Crimean Autonomous Soviet Socialist Republic).

Beginning on the island of Khortytsia, a march began travelling across the Dnipro Hydroelectric Station and into the city itself.

The years 1490 and 1990 are written at the top of the image, separated by an image of a Cossack. An upper caption reads "500 years of Ukrainian Cossacks", while a lower caption reads "Ukrainian Post". The stamp is dated 1991.
