Gandhiji returned to India from South Africa in January 1915. This marked a significant turning point in his life and the beginning of his active involvement in the Indian independence movement.

Gandhiji's Early Life and Work in South Africa:
Before his return to India, Gandhiji spent over two decades in South Africa, where he fought against racial discrimination and injustice. He arrived in South Africa in 1893, initially to provide legal assistance to an Indian merchant. However, he soon became deeply involved in the struggles faced by the Indian community in South Africa.

During his time in South Africa, Gandhiji organized and led various campaigns against discriminatory laws and practices. He advocated for the rights of Indians and fought for their civil liberties. Gandhiji's actions and principles, such as nonviolent resistance and civil disobedience, began to take shape during his experiences in South Africa.

Key Events Leading to Gandhiji's Return to India:
Gandhiji's return to India in 1915 was influenced by several factors and events. Some of the key events leading to his decision are:

1. The Impact of World War I: With the outbreak of World War I in 1914, Gandhiji saw an opportunity to contribute to the independence movement in India. He believed that the war could weaken the British Empire, and it was an opportune moment to mobilize the Indian masses for freedom.

2. The Influence of Gopal Krishna Gokhale: Gokhale, a prominent Indian leader and Gandhiji's mentor, urged him to return to India and join the struggle for independence. Gokhale's guidance and support played a crucial role in shaping Gandhiji's decision.

3. The Indian National Congress: Gandhiji had been following the activities of the Indian National Congress (INC) while in South Africa. The INC had become the primary platform for the freedom movement in India, and Gandhiji felt the need to actively participate in its activities.

The Return and Gandhiji's Role in India:
After his return to India in January 1915, Gandhiji immediately plunged into the freedom struggle. He was warmly welcomed by leaders of the Indian National Congress and other prominent figures. Gandhiji's reputation as a fearless and determined fighter for justice had preceded him, and he was quickly embraced as a leader of the movement.

Gandhiji's return marked the beginning of his Satyagraha campaigns, where he mobilized the masses through nonviolent resistance. He played a pivotal role in various movements, such as the Champaran and Kheda Satyagrahas, the Non-Cooperation Movement, and the Salt March. Gandhiji's leadership and principles inspired millions of Indians and became instrumental in India's eventual independence in 1947.

In conclusion, Gandhiji returned to India from South Africa in January 1915. This marked a crucial point in his life and his active involvement in the Indian independence movement. His experiences in South Africa and the events unfolding in India at the time influenced his decision to return and contribute to the struggle for freedom.
