Why the Ottoman Empire failed to conquer the Mamluks in the late 15th century
Between 1485 and 1491, the Ottoman and Mamluk Sultanates fought a grueling, inconclusive war for regional dominance. Despite Ottoman military might, the Mamluks successfully defended their borders using a network of fortresses and nomadic cavalry, ultimately forcing a stalemate that preserved the status quo until the early 16th century.
The conflict was rooted in long-standing geopolitical friction between two Sunni Muslim powers vying for control over the spice trade and the Holy Cities of Islam. Tensions escalated when Bayezid II ascended the Ottoman throne in 1481 and faced a challenge from his brother, Cem Sultan, who sought refuge in Mamluk domains. Hostility deepened further after the Mamluks seized an Ottoman ambassador returning from India with gifts. The war officially ignited when Bozkurt of Dulkadir, an Ottoman ally, attacked the Mamluk city of Malatya, triggering a series of land and sea campaigns.
Ottoman forces, led by commanders like Karagöz Mehmed Pasha and Hersekzade Ahmed Pasha, struggled to secure the Cilician region. Despite deploying Janissaries and regular units, the Ottomans suffered significant defeats, notably at the Battle of Ağaçarıyı in 1488. The Mamluk military strategy proved highly effective, utilizing a combination of conventional forces and brilliant nomadic cavalry. Furthermore, the Ottomans were hampered by logistical failures, including the destruction of their fleet by a storm, and internal issues, such as the Sultan Bayezid II remaining in Constantinople rather than leading the campaigns personally.
By 1490, both empires were exhausted by the financial burden of the war and the spread of famine and plague. The conflict concluded in May 1491 with a peace treaty that restored the status quo ante bellum, establishing the border at the Gülek Pass. While the Ottomans remained a formidable power, the Mamluks held their ground until the Portuguese incursion into the Indian Ocean in 1505 disrupted their trade routes. This economic strain, combined with later military developments, eventually paved the way for the Ottoman conquest of the Mamluk Sultanate in 1517.
The war also had broader consequences, as the Ottoman preoccupation with the Mamluks limited their ability to assist the Nasrid Dynasty in Granada. Despite sending a fleet under Kemal Reis, Ottoman support proved insufficient, contributing to the fall of Granada in 1492. This period highlights the complex interplay of regional rivalries, where buffer states like the Dulkadirids often dictated the flow of power, shifting allegiances to maintain a fragile balance between the two competing sultanates.
