Why this matters now
These invasions are the bridge between ancient and medieval India — the sequence (Qasim → Ghazni → Ghori), the key battles, and why the Turks succeeded are commonly tested in GS-1.
The Arab conquest of Sind
In 712 CE, the Arab general Muhammad bin Qasim conquered Sind (defeating Raja Dahir), the first major Muslim foothold in India. Arab rule remained largely confined to Sind and Multan and had limited political impact, though it opened cultural and commercial contact.
Mahmud of Ghazni
Mahmud of Ghazni raided India some 17 times (c. 1000–1027), targeting wealthy temple towns (most infamously the Somnath temple, 1025). His aim was plunder, not empire-building in India; the scholar Alberuni came with him and wrote the Kitab-ul-Hind, a valuable account of India.
Muhammad Ghori and the Sultanate
Muhammad Ghori aimed at permanent conquest. He lost the First Battle of Tarain (1191) to Prithviraj Chauhan but won the decisive Second Battle of Tarain (1192). His general (and later slave-king) Qutb-ud-din Aibak founded the Delhi Sultanate in 1206 — the start of Turkish rule in India.
UPSC angle
Know the sequence: Muhammad bin Qasim (712, Sind), Mahmud of Ghazni (raids, Somnath, Alberuni), Muhammad Ghori (Tarain 1191/1192, Prithviraj Chauhan) → Aibak founds the Sultanate (1206).
