During its height, the Ottoman Empire played a critical role in Eastern Europe as a major political and military power. From the late 14th century until the early 20th century, the Ottomans expanded into southeastern Europe, establishing a diverse, multicultural empire that influenced the region's demography, culture, and trade. The empire acted as a bridge between Europe and Asia, facilitating exchanges of goods and ideas. However, its governance often led to tensions due to religious and ethnic diversity. The Ottoman presence also instigated conflicts with European states, shaping the geopolitical landscape of Eastern Europe.
