Explore: Omar

Umar ibn al-Khattab (Arabic: عُمَر بْن ٱلْخَطَّاب, romanized: ʿUmar ibn al-Khaṭṭāb; c. 584 – 644), also spelled Omar, was the second Rashidun caliph, ruling from August 634 until his assassination in 644. He succeeded Abu Bakr (r. 632–634) and is regarded as a senior companion and father-in-law of the Islamic prophet Muhammad. Initially, Umar opposed Muhammad, who was his distant Qurayshite kinsman. However, after converting to Islam in 616, he became the first Muslim to openly pray at the Kaaba. He participated in nearly all of Muhammad’s battles and expeditions, and Muhammad conferred upon him the title al-Fārūq ("the Distinguisher") for his sound judgement. After Muhammad’s death in June 632, Umar pledged allegiance to Abu Bakr as the first caliph and served as his chief adviser. In 634, shortly before his death, Abu Bakr nominated Umar as his successor. During Umar’s reign, the caliphate expanded at an unprecedented rate, conquering the Sasanian Empire and more than two-thirds of the Byzantine Empire. His campaigns against the Sasanians resulted in the conquest of Persia within two years (642–644). According to Jewish tradition, Umar lifted the Christian ban on Jews entering Jerusalem and permitted them to worship there. Umar was assassinated by the Persian slave Abu Lu'lu'a Firuz in 644. Umar is widely credited with expanding the Islamic world beyond Arabia and introducing the Hijri Calendar. Historians generally regard him as one of the most powerful and influential Muslim caliphs in history. In Sunni Islamic tradition, he is revered as a just ruler and a paragon of Islamic virtues, with some hadiths identifying him as the second greatest of the Sahabah after Abu Bakr. In Twelver Shia tradition, however, he is viewed negatively.

Muhammad Umar Mujahid (between 1950 to 1962 – 23 April 2013), commonly known as Mullah Omar or Muhammad Omar, was an Afghan militant leader and founder and the first leader of the Taliban from 1994 until his death in 2013. During the Third Afghan Civil War, the Taliban fought the Northern Alliance and took control of most of the country, establishing its First Islamic Emirate for which Omar began to serve as Supreme Leader in 1996. Shortly after al-Qaeda carried out the September 11 attacks, the Taliban government was toppled by an American invasion of Afghanistan, prompting Omar to go into hiding; he successfully evaded capture by the American-led coalition before dying in 2013 from tuberculosis. Born into a religious family in Kandahar, Omar was educated at local madrasas in Afghanistan. After Afghanistan was invaded by the Soviet Union in 1979, he joined the Afghan mujahideen to fight in the Soviet–Afghan War and he was trained by Amir Sultan Tarar. He served as an important rebel commander during several skirmishes, losing his right eye in an explosion. The Soviets eventually withdrew from the country in 1989 and Afghanistan's Soviet-backed Democratic Republic was toppled in 1992, triggering the Second Afghan Civil War. While initially remaining quiet and focused on continuing his studies, Omar became increasingly discontent with what he perceived as fasād in the country, ultimately prompting him to return to fighting in the Civil War. In 1994, Omar, along with religious students in Kandahar, formed the Taliban, which emerged victorious against other Afghan factions by 1996. Omar led the Taliban to form a Sunni Islamic theocracy headed by the Supreme Council, known as the Islamic Emirate of Afghanistan, which strictly enforced sharia. While ruling between 1996 and 2001, the Taliban were widely condemned for committing massacres against civilians; discrimination against religious and ethnic minorities; banning women from school and most employment; and the destruction of cultural monuments, including the Buddhas of Bamiyan, which Omar personally ordered. After al-Qaeda, which had been given sanctuary in Afghanistan by the Taliban, carried out the September 11 attacks against the United States in 2001, American president George W. Bush demanded that the Taliban extradite al-Qaeda's leader Osama bin Laden to the United States. The Taliban, under the leadership of Mullah Omar, refused to extradite him to the U.S. without concrete evidence linking him to the attacks, and they requested proof of his involvement in 9/11. The United States, however, had enough proof of him being in Afghanistan and under the Taliban's protection, and subsequently began the Global War on Terrorism and led a multinational invasion of Afghanistan in October 2001, greatly bolstered by the anti-Taliban Northern Alliance. By December 2001, the Taliban government had been ousted by the American-led coalition; Omar fled Kandahar, went into hiding in Zabul Province, and delegated operational control of the Taliban to his deputies. Under his command, the Taliban launched an insurgency against the new Afghan government and the coalition. Although Omar was the subject of a decade-long international manhunt, he remained in hiding for the rest of his life. He died in 2013, reportedly due to tuberculosis, which was not revealed publicly until 2015. In 2021, the Taliban deposed the Afghan government and regained power following the fall of Kabul. Omar remains a largely popular figure amongst the Taliban, who view him as a key freedom fighter who defended Afghanistan's Islamic principles – first against the Soviet empire and later against the Western world. Others have criticised him for his method of governance and his religious dogmatism.
