The Pskov Republic was a medieval state that existed from the 12th to the 16th centuries in the region around the city of Pskov in present-day Russia. It was known for its strong governance and military prowess, often defending itself against invasions from neighboring powers, including the Teutonic Knights and the Grand Duchy of Lithuania. The republic operated as a semi-autonomous entity, with a unique political structure that included a council of nobles and a popular assembly. It played a significant role in the trade routes of Northern Europe and was an important cultural center, contributing to the development of Russian architecture and art.
