Budge Budge was the site where the ship Komagata Maru was allowed to land following its return from Vancouver. The ship was chartered by a group of Sikhs to challenge the exclusion laws enacted by Canada to restrict Indian immigration. Upon entry into the harbour, the ship was stopped by a British gunboat, and the passengers were placed under guard. The government of the British Raj saw the men on the Komagata Maru not only as self-confessed lawbreakers, but also as dangerous political agitators. When the ship docked at Budge Budge, the police went to arrest Baba Gurdit Singh and the 20 or so other men that they saw as leaders. He resisted arrest, a friend of his assaulted a policeman and a general riot ensued. Shots were fired and 19 of the passengers were killed. Some escaped, but the remainder were arrested and imprisoned or sent to their villages and kept under village arrest for the duration of the First World War. This incident became known as the Budge Budge Riot.
