The Cossacks are a group of predominantly East Slavic people known for their military prowess and unique culture. Originating in the 15th century, they settled in the steppes of modern-day Ukraine and Russia, forming semi-autonomous communities. Cossacks played a significant role in the expansion of the Russian Empire and were often employed as frontier soldiers. Throughout history, Cossacks have been recognized for their distinctive traditions, including their music, dance, and dress. They participated in various uprisings, such as the Khmelnytsky Uprising in the 17th century, which sought to establish greater autonomy. Their legacy continues to influence the cultural landscape of Eastern Europe today.
