This coin commemorates the formation of the first Ukrainian voluntary military unit. The regiment paved the way for the formation of other Ukrainian units in the Russian army. It participated in the armed opposition of the Ukrainian People`s Republic to Russian aggression. The First Ukrainian Military Congress, which took place in 1917, approved the formation of the first Ukrainian military unit. The congress decided that all 3,200 volunteers should be included in the regiment, and put Yurii Kapkan in command of it. The formation of the First Ukrainian Bohdan Khmelnytskyi Regiment was an important milestone in the creation of Ukraine`s modern army.
