Gandhiji dominated the Indian freedom struggle from 1919 to 1948. That is why this period is known as the Gandhian era in Indian history. During this time, Mahatma Gandhi dominated the Indian National Congress, which in turn was at the forefront of the Indian freedom struggle. Gandhi's first major involvement in Indian politics was during the Non-Cooperation Movement. Sensing a chance for Hindu-Muslim unity, Gandhi cleverly allied with the Khilafat leaders and launched the Non-Cooperation movement against the British colonial government. For the first time in Indian history, he succeeded in ensuring active participation of almost all classes of society in the national mainstream. Women, children, workers, peasants, all previously impervious classes participated in the Non-Cooperation movement because of Gandhi'. Similarly, Gandhi conceptualised the Civil Disobedience Movement and launched the immensely successful Dandi March. Through the Civil Disobedience programme, he sought to take agitational politics to the maximum portion of the Indian populace. This was necessary in order to ensure that the British Government was seriously impaired from governing India. However, following severe repression by the British government and some tactical mistakes on the part of the Congress, the Civil Disobedience Movement could not succeed and lost steam. The Quit India Movement was the last major mass movement launched by the Indian National Congress under the leadership of Mahatma Gandhi. During this movement, Gandhi gave the famous call of 'Quit India' and sustained the movement through his personal sacrifice and exhortations.
