The Ghadar Party, also known as the Ghadr Movement, was a revolutionary movement formed by Punjabi Indians who lived in the United States and Canada in the early 1900s. The Ghadar Party was created with the aim of freeing India from British rule and establishing a national democratic government in the country. The movement took its name from the weekly paper "Ghadar", which was published to commemorate the Revolt of 1857.

The two founders of the Ghadar Party were Sohan Singh Bhakna and Lala Hardayal. Both of them were exiled to the United States by the British authorities for their revolutionary activities in India. They were among the many Punjabi immigrants who had moved to the United States in search of better economic opportunities. However, they never forgot their homeland and continued to work towards the cause of Indian independence.

The Ghadar Party gained momentum after the outbreak of World War I in 1914. The party leaders believed that the war provided an opportunity for them to strike against the British Empire, which was weakened by the war effort. They hoped that an armed revolt in India would be able to take advantage of this situation and gain independence for the country.

The Ghadar Party had a strong presence in the United States, where it was able to raise funds and recruit members. It also had a significant impact in Canada, where it organized a number of strikes and protests against British rule. The party also sent a number of its members to India to foment rebellion against the British authorities.

The Ghadar Party faced many challenges in its struggle for Indian independence. The British authorities were quick to crack down on the party's activities, and many of its leaders were arrested and deported. The party also faced internal divisions and was unable to maintain a unified front.

Despite its shortcomings, the Ghadar Party played an important role in the struggle for Indian independence. It inspired a generation of Indians to fight for their freedom and laid the groundwork for the Indian independence movement that would eventually succeed in 1947. The legacy of the Ghadar Party continues to inspire many people today who seek to challenge injustice and fight for a better world.
