Mu'izz al-Din Muhammad ibn Sam, known as Muhammad of Ghor, was a prominent monarch of the Ghurid dynasty, born around 1144 in the Ghor region of present-day Afghanistan. He ruled from 1173 until his assassination in 1206, during which he and his elder brother, Ghiyath al-Din Muhammad, governed in a dyarchy. While Ghiyath managed the western territories from Firozkoh, Muhammad focused on expanding Ghurid influence into South Asia, laying the groundwork for Islamic rule that would endure for centuries.
In his early years, Muhammad served as the governor of the southern Ghurid Empire, where he successfully subjugated the Oghuz Turks and annexed Ghazni. His military campaigns led him to cross the Indus River in 1175, capturing key cities like Multan and Uch. However, his initial attempts to penetrate further into India faced setbacks, including a significant defeat near Mount Abu against Rajput forces. Undeterred, he regrouped and ultimately expelled the Ghaznavids from Punjab by 1186, securing the Khyber Pass as a strategic entry point into northern India.
Despite facing challenges, including a serious injury in 1191 during a battle against Prithviraj Chauhan, Muhammad's resilience shone through. He returned to the battlefield the following year, achieving a decisive victory and executing Prithviraj. After the death of his brother in 1203, Muhammad ascended to the throne of Firozkoh, becoming the supreme Sultan of the Ghurid Empire. However, his reign faced turmoil, including a devastating defeat against the Khwarazmians, which led to a decline in Ghurid power.
In his final years, Muhammad sought to reclaim lost territories and quell insurrections within his empire. Tragically, he was assassinated on March 15, 1206, while praying by the Indus River. His death marked a turning point, leading to the rapid decline of the Ghurid dynasty and paving the way for the rise of the Delhi Sultanate under his former commander, Qutbuddin Aibak.
