Sultan Suleiman the Magnificent receives Barbarossa, 1533

Upon ascension to the throne, Sultan Suleyman wanted to increase Ottoman might at sea, which was relatively weak in those years. This miniature shows young Suleyman receiving Barbarossa Hayreddin Pasha, who will soon become the grand admiral (1533). With Barbarossa joining the Ottomans, the undisputable might and supremacy of the Ottomans on land was achieved at sea as well.
