The Ghadar Movement or Ghadar Party was an early 20th century, international political movement founded by expatriate Indians to overthrow British rule in India. Many of the Ghadar Party founders and leaders, including Sohan Singh Bhakna, would go on and join the Babbar Akali Movement and would help it in logistics as a party and publishing its own newspaper in the post-World War 1 era. The early movement was created by revolutionaries who lived and worked on the West Coast of the United States and Canada, but the movement later spread to India and Indian diasporic communities around the world. The official founding has been dated to a meeting on 15 July 1913 in Astoria, Oregon, and the group would splinter into two factions the first time in 1914, with the Sikh-majority faction known as the “Azad Punjab Ghadar” and the Hindu-majority faction known as the “Hindustan Ghadar.” The Azad Punjab Ghadar Party’s headquarters and anti-colonial newspaper publications headquarters would remain in the Stockton Gurdwara located in Stockton, California, whereas the Hindustan Ghadar Party’s headquarters and Hindustan Ghadar newspaper would relocate to be based in nearby Oakland, a suburb of San Francisco, California.

The British Raj was the rule of the British Crown on the Indian subcontinent; it is also called Crown rule in India, or Direct rule in India, and lasted from 1858 to 1947. The region under British control was commonly called India in contemporaneous usage and included areas directly administered by the United Kingdom, which were collectively called British India, and areas ruled by indigenous rulers, but under British paramountcy, called the princely states. The region was sometimes called the Indian Empire, though not officially.
