The Ghadar movement was a revolutionary association of Indians who were primarily based in San Francisco, California, USA. The movement was active from 1913 to 1918 and was aimed at overthrowing British colonial rule in India. The word "Ghadar" means "revolt" or "mutiny" in Punjabi. The movement was led by a group of Punjabi Indians who had emigrated to the United States and Canada in the early 20th century, mainly to work on farms and in other manual labor jobs.

The Ghadar movement aimed to unite and mobilize Indians living abroad in support of India`s independence struggle. The movement published a weekly newspaper called Ghadar, which was published in several languages and distributed throughout India and other parts of Asia. The paper provided news and commentary on political events in India and called for the overthrow of British rule.

The Ghadar movement also attempted to incite a mutiny among Indian soldiers stationed in British India. In February 1915, a group of Ghadarites attempted an armed uprising in Punjab, but it was quickly suppressed by the British authorities. Many Ghadarites were arrested and executed, while others fled to other countries.
