Madan Lal Dhingra assassinated Sir William Curzon Wyllie, an aide to the Secretary of State for India, in London in 1909.

Dhingra was a young Indian nationalist who was angry about British rule in India and believed that violence was necessary to bring about change. On July 1, 1909, he shot Wyllie at a public meeting in London, and he was subsequently arrested, tried, and sentenced to death. Dhingra was hanged on August 17, 1909, and his execution was widely publicized in both India and the United Kingdom. The assassination of Sir William Curzon Wyllie was a significant event in the history of the independence movement in India and was seen as a major blow to the British government.
