Mahmud Ghaznavi, the ruler of Ghazni, invaded India 17 times between 1000 and 1027 CE. His invasions were driven by the desire for wealth, expansion of his empire, and the spread of Islam. He targeted rich temples and prosperous cities such as Mathura, Kannauj and especially the Somnath Temple, which he plundered in 1025 CE. Although he did not attempt long-term territorial annexation in India, his repeated raids weakened Indian kingdoms, particularly the Rajput powers. These invasions created political instability, paving the way for later Muslim conquests in North India. His campaigns hold major significance in medieval Indian history.
