Q: The First Battle of Tarain was fought in  

In 1191, Mu'izz al-Din captured the fortress of Bhatinda in East Punjab, which was on the frontier of Prithviraj Chauhan's domains. Prithviraj marched on to Bhatinda and met his enemy at a place called Tarain (also called Taraori) near the ancient town of Thanesar. The Ghurid army initiates battle by attacking with cavalry who launch arrows at the Rajput center. The forces of Prithviraj counter-attack from three sides and dominate the battle, pressuring the Ghurid army into a withdrawal. Meanwhile, Mu'izz al-Din is wounded in personal combat with Prithviraj's brother, Govind Tai. Prithviraj succeeded in stopping the Ghurid advance towards Hindustan in the first battle of Tarain. He did not pursue Ghori's army either not wanting to invade hostile territory or misjudging Ghori's ambition, instead electing to retake the fortress of Bhatinda.

Mu'izz ad-Din Muhammad Ghori, born Shihab ad-Din (1149-March 15, 1206), also known as Muhammad of Ghor, was Sultan of the Ghurid Empire along with his brother Ghiyath ad-Din Muhammad from 1173 to 1202, and as the supreme ruler of the Ghurid Empire from 1202 to 1206.

Mu'izz ad-Din was one of the greatest rulers of the Ghurid dynasty and is credited with laying the foundation of Muslim rule in South Asia, that lasted for several centuries. He reigned over a territory spanning over parts of modern-day Afghanistan, Bangladesh, Iran, India, Pakistan, Tajikistan, and Turkmenistan.
