Muhammad of Ghor in the context of "Muhammad Bakhtiyar Khalji"

The Delhi Sultanate or the Sultanate of Delhi was a late medieval empire primarily based in Delhi that stretched over large parts of the Indian subcontinent for more than three centuries. The sultanate was established in 1206 in the former Ghurid territories in India. The sultanate's history is generally divided into five periods: Mamluk (1206–1290), Khalji (1290–1320), Tughlaq (1320–1414), Sayyid (1414–1451), and Lodi (1451–1526). It covered large swaths of territory in modern-day India, Pakistan, Bangladesh, as well as some parts of southern Nepal.

The foundation of the Sultanate was established by the Ghurid conqueror Muhammad Ghori, who routed the Rajput Confederacy, led by Ajmer ruler Prithviraj Chauhan, in 1192 near Tarain in a reversal of an earlier battle. As a successor to the Ghurid dynasty, the Delhi Sultanate was originally one of several principalities ruled by the Turkic slave-generals of Muhammad Ghori, including Taj al-Din Yildiz, Qutb ud-Din Aibak, Bahauddin Tughril and Nasir ad-Din Qabacha, that had inherited and divided the Ghurid territories amongst themselves. Khalji and Tughlaq rule ushered a new wave of rapid and continual Muslim conquests deep into South India. The sultanate finally reached the peak of its geographical reach during the Tughlaq dynasty, occupying most of the Indian subcontinent under Muhammad bin Tughluq. A major political transformation occurred across North India, triggered by the Central Asian king Timur's devastating raid on Delhi in 1398, followed soon afterwards by the re-emergence of rival Hindu powers such as Vijayanagara Empire and Kingdom of Mewar asserting independence, and new Muslim sultanates such as the Bengal and Bahmani Sultanates breaking off. In 1526, Timurid ruler Babur invaded northern India and conquered the Sultanate, leading to its succession by the Mughal Empire.

Afghanistan is a mountainous landlocked country at the crossroads of Central Asia and South Asia. Some of the invaders in the history of Afghanistan include the Maurya Empire, the ancient Macedonian Empire of Alexander the Great, the Rashidun Caliphate, the Mongol Empire led by Genghis Khan, the Ghaznavid Empire of Turkic Mahmud of Ghazni, the Ghurid Dynasty of Muhammad of Ghor the Timurid Empire of Timur, the Mughal Empire, various Persian Empires, the British Empire, the Soviet Union, and most recently the United States with a number of allies. A reduced number of NATO troops remained in the country in support of the government. Just prior to the American withdrawal in 2021, the Taliban regained control of the capital Kabul and most of the country. They changed Afghanistan's official name to the Islamic Emirate of Afghanistan.

The Muslim conquests on the Indian subcontinent mainly took place between the 13th and the 18th centuries, establishing the Indo-Muslim period. Earlier Muslim conquests on the Indian subcontinent include the invasions which started in the northwestern Indian subcontinent (modern-day Pakistan), especially the Umayyad campaigns in India. Later during the 8th century, Mahmud of Ghazni, sultan of the Ghaznavid Empire, invaded vast parts of Punjab and Gujarat during the 11th century. After the capture of Lahore and the end of the Ghaznavids, the Ghurid ruler Muhammad of Ghor laid the foundation of Muslim rule in India in 1192. In 1202, Muhammad Bakhtiyar Khalji led the Muslim conquest of Bengal, marking the easternmost expansion of Islam at the time.

The Ghurid Empire soon evolved into the Delhi Sultanate in 1206, ruled by Qutb ud-Din Aibak, the founder of the Mamluk dynasty. With the Delhi Sultanate established, Islam was spread across most parts of the Indian subcontinent. In the 14th century, the Khalji dynasty under Alauddin Khalji, extended Muslim rule southwards to Gujarat, Rajasthan, and the Deccan. The successor Tughlaq dynasty temporarily expanded its territorial reach to Tamil Nadu. The disintegration of the Delhi Sultanate, capped by Timur's invasion in 1398, caused several Muslim sultanates and dynasties to emerge across the Indian subcontinent, such as the Gujarat Sultanate, Malwa Sultanate, Bahmani Sultanate, Jaunpur Sultanate, Madurai Sultanate, and the Bengal Sultanate. Some of these, however, were followed by Hindu reconquests and resistance from the native powers and states, such as the Telugu Nayakas, Vijayanagara, and Rajput states under the Kingdom of Mewar.

The Ghurid dynasty (also spelled Ghorids; Persian: دودمان غوریان, romanized: Dudmân-e Ğurīyân; self-designation: شنسبانی, Šansabānī) was a culturally Persianate dynasty of eastern Iranian Tajik origin, which ruled from the 8th-century in the region of Ghor, and became an Empire from 1175 to 1215. The Ghurids were centered in the hills of the Ghor region in the present-day central Afghanistan, where they initially started out as local chiefs. They gradually converted to Sunni Islam after the conquest of Ghor by the Ghaznavid ruler Mahmud of Ghazni in 1011. The Ghurids eventually overran the Ghaznavids when Muhammad of Ghor seized Lahore and expelled the Ghaznavids from their last stronghold.

The Ghurids initially ruled as vassals of the Ghaznavids and later of the Seljuks. However, during the early 12th-century the long-standing rivalry between the Seljuks and Ghaznavids created a power vacuum in eastern Afghanistan and Panjab which the Ghurids took advantage of and began their territorial expansion. Ala al-Din Husayn ended the Ghurid subordination to the Ghaznavids, ruthlessly sacking their capital, although he was soon defeated by the Seljuks after he stopped paying tribute to them. The Seljuk imperial power, however, was itself swept away in eastern Iran with the contemporaneous advent of the Khwarazmian Empire.

Prithviraja III (IAST: Pṛthvī-rāja; 28 May 1166 – February 1192), popularly known as Prithviraj Chauhan or Rai Pithora, was a king from the Chauhan (Chahamana) dynasty who ruled the territory of Sapadalaksha, with his capital at Ajmer in present-day Rajasthan in north-western India. Ascending the throne as a minor in 1177 CE, Prithviraj inherited a kingdom which stretched from Thanesar in the north to Jahazpur (Mewar) in the south, which he aimed to expand by military actions against neighbouring kingdoms, most notably defeating the Chandelas.

Prithviraj led a coalition of several Rajput kings and defeated the Ghurid army led by Muhammad of Ghor near Taraori in 1191 However, in 1192, Muhammad returned with an army of Turkish mounted archers and defeated the Rajput army on the same battlefield. Prithviraj was captured and summarily executed, although his minor son Govindaraja was reinstated by Muhammad as his puppet ruler in Ajmer. His defeat at Tarain is seen as a landmark event in the Islamic conquest of India, and has been described in several semi-legendary accounts, most notably the Prithviraj Raso.

The Second Battle of Tarain was fought in 1192 between the Ghurid forces of Muhammad Ghuri and the Rajput Confederacy of Prithviraj Chauhan. It took place near Tarain (modern Taraori), which is 110 kilometres (68 mi), north of Delhi. The battle ended in a decisive victory for the invading Ghurids and their successful penetration into the north Indian plain.

The battle is regarded as a watershed event in Medieval India history as it led to the destruction of Rajput powers for a while and laid the foundation of Muslim rule in North India, which led to the establishment of Delhi Sultanate.

First Battle of Tarain, also known as the First Battle of Taraori, was fought on 14 January 1191 between the Ghurid forces led by Muhammad of Ghor and the Rajput Confederacy led by Prithviraj Chauhan, near Tarain (modern Taraori in Haryana, India). The battle ended in a victory for the Rajputs; however, Muhammad of Ghor managed to escape and returned to Ghazni.

After the Ghurid armies were routed, they retreated to Ghazni and left garrison of 2,000 soldiers under Zia ud-Din Tulaki to secure the fort of Tabarhind (present day Bhatinda) to delay the Rajput army and was successful in keeping them at bay for thirteen months, while Muhammad of Ghor, during these months, raised a stronger army of 120,000 men, and invaded again, leading to the Second Battle of Tarain, which ended Chauhan's rule.

Taj al-Din Yildiz (also spelled Yaldiz, Yildoz, and Yalduz, Persian: تاج‌ الدین یلدوز) was a Turkic ghulam of the Ghurid dynasty, who, after the death of Sultan Muhammad of Ghor, became the de facto ruler of Ghazni, while, however, still recognizing Ghurid authority.
