Who Were The Best Ottoman Military Leaders?

The Ottoman Empire had its share of great military leaders. As one of the biggest and most powerful states in world history, it required military prowess to maintain stability and continue expansion. Consider Mehmed II, who oversaw the conquest of Constantinople, or Hayreddin Barbarossa, who helped the Ottomans gain partial control of North Africa. Exploring the best Ottoman military leaders in detail, therefore, helps us paint a picture of why the empire became as powerful as it did.

Mehmed II (1432 to 1481)

After briefly becoming sultan in 1444, Mehmed II returned to the throne in 1451. The timing was serendipitous, since the Ottomans were preparing to launch their final assault on the Byzantine Empire. The battle for the Byzantine capital of Constantinople began in April 1453. Mehmed smartly adopted a combined arms approach, utilizing artillery, infantry, engineers, and naval forces to besiege the city. His use of gunpowder is particularly notable. However, perhaps his most daring maneuver came when the Byzantines put a massive chain in the water to block access to the Golden Horn, a natural harbor. Rather than accepting this, Mehmed ordered the construction of a massive road of greased logs. The Ottomans then carried their ships over land, using the road, and put them back in the water on the other side of the chain. This had a devastating psychological impact on the Byzantine defenders and forced them to divert troops from elsewhere to contend with the Ottoman naval bombardment.

Constantinople fell on May 29th, 1453. In one fell swoop, Mehmed both ended the Byzantine (and Roman) Empire and established the Ottoman Empire as a major world power. He didn't stop there, spending the rest of his reign accumulating territory in places like Serbia, Bosnia, Albania, Anatolia, Greece, and Crimea. Despite passing away at the relatively young age of 49, Mehmed II was still arguably the most consequential sultan and military leader in Ottoman history up to that point.

Selim I (1470 to 1520)

Selim I ruled the Ottoman Empire from 1512 to 1520. During these eight years, he oversaw some of the most transformative military campaigns in its history. In 1514, he defeated the Persia-based Safavid Empire at the Battle of Chaldiran. This strengthened Ottoman influence in eastern Anatolia and signified the beginning of a forty-year conflict with the Safavids. Selim then turned his attention to the Egypt-based Mamluk Sultanate. Following several battles at places like Dabiq in 1516 and Ridaniya, the Mamluks collapsed, and the Ottomans came to control most of their territory, including Egypt, Syria, and the Hejaz.

The Hejaz was particularly important, since it was home to the two holiest cities in Islam, Mecca and Medina. The Ottoman Empire now had a reasonable claim to being a caliphate, a state that functioned as the political leader of the global Muslim community. Selim I is thus considered one of the most consequential military leaders in Ottoman history, since he oversaw the empire's transformation into arguably the predominant Islamic power in the world.

Suleiman The Magnificent (1494 to 1566)

While everyone discussed in this article is important, Suleiman the Magnificent stands above them all. Ruling from 1520 to 1566, he was the longest-serving sultan in Ottoman history. His reign is also associated with the Ottoman Golden Age, a period when the empire reached the height of its cultural, political, and military power. Concerning the military, Suleiman personally led several campaigns into Central Europe. The Battle of Mohács in 1526 was particularly consequential. The Ottomans destroyed the Hungarian army, terrifying the rest of Europe and paving the way for the partition of Hungary in 1541.

Suleiman also oversaw campaigns against the Safavids in the east. The first one, from 1531 to 1535, resulted in the Ottomans making major territorial gains and capturing cities like Tabriz and Baghdad. Later campaigns in the 1540s and 1550s further cemented Ottoman control over places like the Caucasus and Iraq, though they were unable to permanently defeat the Safavids. Finally, Suleiman was partially responsible for Ottoman incursions into North Africa. Crucially, however, he delegated responsibility for these campaigns to another great military leader, Hayreddin Barbarossa.

Hayreddin Barbarossa (1478 to 1546)

Hayreddin Barbarossa was likely the most important naval commander in Ottoman history. Born on the island of Lesbos around 1478 (his exact birth year is unknown), he began his career as a Barbary pirate, or corsair, with his brother, Aruj Barbarossa. The two established a foothold in the city of Algiers and involved themselves in the local Muslim struggle against the Spanish. Aruj was killed in 1518, and Hayreddin inherited all his positions and titles. Despite now being the most powerful pirate in the region, he realized that he couldn't fight the Spanish alone. Therefore, he offered Algiers to the Ottomans in exchange for military support. The Ottomans accepted, and Hayreddin was now officially part of the Ottoman navy.

Over the next 20 years, Hayreddin Barbarossa established Ottoman influence in places like Algiers, Tunis, and the broader North African coastline. Such achievements led to him becoming Grand Admiral of the Ottoman navy in 1533. He then won the Battle of Preveza in 1538 against a coalition of Christian states. This terrified the rest of Europe and made the Ottomans the dominant sea power of the Mediterranean for decades to come.

Impact And Legacy

Several great military leaders shaped the course of Ottoman history. Mehmed II oversaw the conquest of Constantinople and further incursions into places like Anatolia and the Balkans. Selim I defeated the Mamluks and made the Ottoman Empire the world's pre-eminent Islamic power. Suleiman the Magnificent fought wars in Central Europe and against the Safavids. Finally, Hayreddin Barbarossa helped the Ottomans control parts of North Africa and made them the dominant naval power in the Mediterranean.
