The Separate Andhra Movement, which emerged within the Madras Province during the early 20th century, played a crucial role in the formation of the Andhra Pradesh state post-independence. It was a significant chapter in the history of regional politics in India, driven by the linguistic and cultural aspirations of the Telugu-speaking people who felt marginalized within the Madras Presidency, where they were under the dominance of Tamil political and cultural influences. This paper examines the origins of the movement, its evolution, key leaders, events, and the political negotiations that culminated in the creation of Andhra Pradesh. It also explores the role of the Indian National Congress, the opposition to the movement, and the eventual triumph of the Telugu-speaking people's demands. The movement had far-reaching implications for regional autonomy and set a precedent for the linguistic reorganization of states in post-colonial India.
