What major event galvanized the british effort to drive the french out of India?

The major event that galvanized the British effort to drive the French out of India was the Seven Years' War (1756-1763), particularly its Indian theater known as the Anglo-French War in India. The conflict intensified British and French competition for dominance in the region, culminating in key battles such as the Battle of Plassey in 1757. British victories during this war significantly weakened French influence in India, allowing the British East India Company to expand its control over vast territories. This shift marked the beginning of British colonial dominance in India.
