Explanation:

The Ghadar Party was indeed organized as a revolutionary group of Indians abroad with the aim to wage a violent uprising against British rule in India. They also sought to encourage soldiers of the British Indian Army to join the revolt against the British. The British authorities, utilizing the powers granted under the Defence of India Act of 1915, were able to curb the movement before it could significantly impact British rule. The Act was an emergency measure intended to curtail nationalist and revolutionary activities during and in the aftermath of the First World War, granting the executive extensive powers for preventive detention, internment without trial, and restrictions on writing, speech, and movement.
