History of Ottoman Sultan Selim I: Why was he called “the Grim”?
Selim I, commonly known as “Selim the Grim” or “Selim the Resolute” (Yavuz Sultan Selim in Turkish), was the Sultan of the Ottoman Empire from 1512 to 1520. His reign, though short, marked a significant period in Ottoman history, characterized by vast territorial expansion, military conquests, and significant internal reforms.
In the article below, World History Edu provides an extensive exploration of Selim’s life, reign, and legacy, encompassing his major achievements and controversies.
Early Life and Ascendancy
Selim I was born on October 10, 1470, in Amasya, a city in modern-day northern Türkiye. He was the youngest son of Sultan Bayezid II and Ayse Hatun. Selim’s early years are not well-documented, but it is known that he received a comprehensive education typical of Ottoman princes, focusing on military training, governance, and Islamic studies.
Selim’s rise to prominence began when he was appointed the governor of Trabzon, a strategically important province in northeastern Anatolia. This position allowed him to develop his administrative skills and military acumen, particularly in his conflicts with the Safavid Persians, a rising power in the east.
Military Achievements in Trabzon
As governor, Selim quickly made a name for himself through a series of military campaigns against the Safavids. In 1505, he led a daring campaign against Shah Ismail’s brother, whose forces vastly outnumbered his own. Despite the odds, Selim’s tactical brilliance resulted in a decisive victory, with his 450 troops overcoming a force of 3,000. This victory not only showcased Selim’s military prowess but also his ability to inspire and lead his men under challenging circumstances.
In 1507, Selim achieved another significant victory at the Battle of Erzincan, where he defeated a larger Safavid force that had invaded Ottoman territory. This battle further solidified his reputation as a formidable military leader. His campaigns in the Caucasus in 1508 and subsequent incorporation of western Georgia into the Ottoman Empire expanded his influence and demonstrated his strategic vision.

In 1510, Selim once again defeated the Safavids, showcasing his relentless military strategy. These victories highlighted his capability as a military leader, contrasting sharply with his father, Bayezid II, who was seen as a weaker ruler. Image: An artwork portraying Selim.
Path to the Throne
Despite his military successes, Selim faced a significant challenge in his quest for the throne. His father, Sultan Bayezid II, favored his older brother, Ahmed, as his successor. This decision was met with resistance from Selim, who believed his military achievements and governance experience made him the more suitable heir. The Ottoman practice of primogeniture was not strictly followed, and succession often involved power struggles among the Sultan’s sons.
The dispute over succession led to a civil war within the Ottoman Empire. Initially, Selim was defeated, but he quickly regrouped and launched another campaign against his father and brother. In a decisive battle, Selim’s forces, though outnumbered, emerged victorious. He forced his father to abdicate and exiled him to Didymoteicho, where Bayezid II died shortly afterward. Selim ascended to the throne on April 24, 1512.

Selim’s most notable victory came in 1505 when his 450 troops defeated a force of 3,000 led by Shah Ismail’s brother. This underdog victory was followed by another triumph at the Battle of Erzincan in 1507, further solidifying his military prowess. Image: A painting showing Selim during his campaign in Egypt.
Consolidation of Power
Upon becoming Sultan, Selim moved swiftly to consolidate his power. To eliminate potential threats to his rule, he ordered the execution of his brothers and their sons, a common practice in Ottoman succession struggles. This ruthless approach earned him the nickname “the Grim.” However, it also ensured the stability of his reign by removing rival claimants to the throne.
Selim’s actions were not without controversy. The execution of royal family members was seen as a barbaric practice by many, even within Ottoman society. Selim had them strangled with silk cords, a method that became standard practice for eliminating political rivals in the Ottoman court.
Religious Policies and Sectarian Conflict
Selim was a devout Sunni Muslim, and his reign was marked by significant religious policies aimed at consolidating Sunni Islam within the empire. One of his primary targets was the Safavid Empire, which was promoting Shia Islam. The religious divide between Sunni and Shia Muslims was a central issue in the region, and Selim sought to eliminate Shia influence within his territories.
In a controversial and brutal campaign, Selim ordered the massacre of Shi’ite Muslims within the Ottoman Empire. He compiled a list of Shi’ites aged 7 to 70 and systematically exterminated them. This massacre is considered one of the darkest chapters in Ottoman history, reflecting Selim’s determination to enforce religious conformity and eliminate sectarian divisions.

Despite his brief reign, Selim the Grim is one of the most renowned Ottoman sultans due to his significant territorial expansions and military conquests, which laid the foundation for his successor, Suleiman the Magnificent. However, his reign was also marked by ruthless actions and controversies. Image: A painting of Suleiman the Magnificent by Italian artist Titian.
Major Military Campaigns
Selim’s reign is most notable for his ambitious military campaigns, which significantly expanded the Ottoman Empire’s territory and influence.
Battle of Chaldiran (1514)
One of Selim’s most significant military achievements was his victory at the Battle of Chaldiran on August 23, 1514. This battle was a decisive confrontation between the Ottoman Empire and the Safavid Empire. Selim’s forces, equipped with superior firearms and artillery, defeated Shah Ismail’s army. The victory at Chaldiran allowed the Ottomans to annex large parts of eastern Anatolia and northern Iraq, significantly weakening the Safavid state.
The Battle of Chaldiran had profound implications for the balance of power in the region. It marked the beginning of a long series of Ottoman-Persian Wars that would continue for decades. Shah Ismail, who was wounded in the battle, retreated and never again engaged in open conflict with the Ottomans.

Conquest of the Mamluk Sultanate
Following his success against the Safavids, Selim turned his attention to the Mamluk Sultanate of Egypt, a major power in the Middle East. The Mamluks controlled the holy cities of Mecca and Medina, making them a significant target for Selim, who sought to enhance the Ottoman Empire’s religious prestige.
In 1516, Selim led a campaign against the Mamluks, winning a decisive victory at the Battle of Marj Dabiq near Aleppo. This victory opened the way for the Ottoman conquest of Syria and Egypt. In 1517, Selim’s forces defeated the Mamluks at the Battle of Ridanieh, leading to the fall of Cairo. The last Mamluk Sultan, Tuman Bay II, was captured and executed, marking the end of the Mamluk Sultanate.
The conquest of Egypt was a major milestone for the Ottoman Empire. It brought the holy cities of Mecca and Medina under Ottoman control, significantly enhancing the empire’s religious legitimacy. It also gave the Ottomans control over the vital trade routes in the eastern Mediterranean and the Red Sea.
Administrative and Economic Reforms
In addition to his military achievements, Selim implemented significant administrative and economic reforms to strengthen the empire. He reorganized the provincial administration to ensure more effective governance and control over newly acquired territories. He also implemented measures to improve the tax system, increasing state revenue and ensuring the financial stability of the empire.
Selim’s reign saw the development of a more centralized and bureaucratic state, with greater control exerted by the central government over provincial administrations. These reforms laid the foundation for the further expansion and consolidation of the Ottoman Empire under his successors.

- Selim the Grim’s mother was Ayse Hatun, a Greek woman known as Gülbahar after her marriage.
- Ottoman Sultan Selim I was described as tall and broad shouldered with an impressive moustache.
- He was fond of poetry, writing poems in Turkish and Persian. He wrote most of his poems under the nicknameMahlas Selimi. In some accounts, he was described as having respect for intellectuals more than generals and bureaucrats.
Death and Legacy
Selim I died on September 22, 1520, at the age of 49. The exact cause of his death remains uncertain, with theories ranging from poisoning to cancer or the plague. Despite his relatively short reign, Selim left a lasting legacy that had a profound impact on the Ottoman Empire.
Selim’s most significant legacy was the territorial expansion he achieved, which transformed the Ottoman Empire into a major power in the Middle East and the Islamic world. His conquests in the east and south significantly increased the empire’s size and influence, setting the stage for further expansion under his son and successor, Suleimanthe Magnificent.
Selim’s ruthlessness in eliminating rivals and enforcing religious conformity also left a lasting impact on Ottoman governance. His use of silk cords for executions became a standard practice for dealing with political opponents, reflecting the harsh measures he employed to maintain his authority.

Selim I’s short but impactful reign set the stage for the golden age of the Ottoman Empire under Suleiman the Magnificent, making him one of the most important figures in Ottoman history. The mosque commissioned by Suleiman in his honor, the Yavuz Selim Mosque in Istanbul, stands as a testament to Selim the Grim’s enduring legacy.
