About the Turkish Invasions of India
The Turkish invasions of India in the 11th and 12th centuries changed the course of Indian history. Unlike earlier invaders such as the Greeks, Shakas or Hunas, who settled and merged into Indian society, the Turks came with a religion (Islam), a new culture and a strong desire for conquest. The invasions began with the raids of Mahmud of Ghazni and culminated in the establishment of the Delhi Sultanate by Muhammad Ghori’s generals.
Before the Turks, an Arab invasion had taken place in 712 AD, when Muhammad bin Qasim conquered Sindh and defeated Raja Dahir. However, this conquest remained limited to Sindh.
Mahmud of Ghazni
Mahmud of Ghazni (997–1030 AD) was the son of Sabuktigin, the founder of the Ghaznavid dynasty. The Ghaznavids were originally Turkish slaves who ruled from Ghazni in Afghanistan. Mahmud is said to have invaded India seventeen times. His invasions were mainly plundering raids rather than attempts to rule India — he annexed only Punjab.
In 1001 AD he defeated the Shahi ruler Jayapala; later he defeated Anandapala. In 1025 AD he attacked and plundered the famous Somanatha temple in Gujarat. Mahmud was also a great patron of art and learning: his court included the scholar Al-Biruni, who wrote the Kitab-ul-Hind (Tahqiq-i-Hind) after studying Indian sciences and religion, and the poet Firdausi, author of the Shahnama. Because of his destruction of temples, Mahmud is called the “idol breaker”.
Muhammad Ghori
Muhammad Ghori (Muizzuddin Muhammad bin Sam, also called Shihabuddin) was the ruler of Ghor (Ghur) in Afghanistan. Unlike Mahmud, he wanted to establish a permanent empire in India. In 1191 AD, at the First Battle of Tarain, he was defeated by Prithviraj Chauhan of Ajmer. He returned the next year and won the Second Battle of Tarain (1192 AD), in which Prithviraj was defeated and killed.
In 1194 AD Ghori defeated Jaichandra of Kannauj at the Battle of Chandawar. His capable slave-general Qutbuddin Aibak conquered large parts of northern India and later founded the Slave (Mamluk) dynasty. Muhammad Ghori was assassinated in 1206 AD, and after his death Qutbuddin Aibak became the first Sultan of Delhi.

Why the Turkish Invasions Matter for Exams
This topic connects early medieval India with the Delhi Sultanate and is frequently asked. Common questions: Who conquered Sindh in 712 AD? (Muhammad bin Qasim.) How many times did Mahmud of Ghazni invade India? (About seventeen times.) Which temple did Mahmud plunder in 1025 AD? (Somanatha.) Who wrote the Kitab-ul-Hind? (Al-Biruni.) Who defeated Prithviraj Chauhan in the Second Battle of Tarain? (Muhammad Ghori.) A common trap is to think that Mahmud of Ghazni annexed all of India — in fact he mainly plundered and annexed only Punjab. Another trap is to confuse the First and Second Battles of Tarain.
How to Prepare This Topic
- Separate the two phases. Mahmud of Ghazni (raids) and Muhammad Ghori (conquest).
- Learn the key battles. Tarain I (1191), Tarain II (1192), Chandawar (1194) and the earlier Arab conquest of Sindh (712).
- Remember the scholars. Al-Biruni (Kitab-ul-Hind) and Firdausi (Shahnama).
- Link the consequences. The invasions led directly to the Delhi Sultanate and Indo-Islamic culture.
- Do not mix the dates. Tarain I = 1191, Tarain II = 1192, Chandawar = 1194, Ghori’s death = 1206.
Common Exam Traps
- Mahmud of Ghazni raided and plundered; Muhammad Ghori established an empire.
- Prithviraj Chauhan won the First Battle of Tarain (1191) but lost the Second (1192).
- Muhammad bin Qasim conquered Sindh in 712 AD, much earlier than Mahmud.
- Al-Biruni wrote the Kitab-ul-Hind; Firdausi wrote the Shahnama.
- Qutbuddin Aibak founded the Slave dynasty — not Muhammad Ghori himself.
