The Cossacks are a group of predominantly East Slavic people known for their unique culture and military traditions. They originally emerged in the 15th century in the regions of modern-day Ukraine and Russia. Cossacks were often semi-nomadic, living in communities that valued independence and self-governance. They played a significant role in the expansion of the Russian Empire and were known for their horsemanship and combat skills. Cossacks are traditionally organized into military units called hosts, each with its own leadership and customs. Their society is characterized by a strong sense of community, with a focus on loyalty, bravery, and a rich folklore. Today, Cossack heritage is celebrated through festivals, music, and dance, preserving their historical identity.
