15. Ottoman Empire (15th Century)
The Ottoman Empire surged to prominence in the 15th century, famously conquering Constantinople in 1453 and transforming it into Istanbul. This victory not only ended the Byzantine Empire but also established the Ottomans as a powerful bridge between Europe and Asia. Their skilled military and innovative administration laid the groundwork for an empire that would dominate for centuries, influencing politics, trade, and culture across three continents (via BBC: The Ottomans).
