I got a question for you: The demand for states to be organised on a linguistic basis was developed even before India achieved independence from British rule. A first-of-its-kind linguistic movement started in 1895, in what is now Odisha. The movement gained momentum in later years with the demand for a separate Orissa Province to be formed by bifurcating the existing Bihar and Orissa Province. Due to the efforts of Madhusudan Das, the Father of Oriya nationalism, the movement eventually achieved its objective in 1936, when Orissa Province became the first Indian state (pre-independence) to be organised on the basis of common languages.

Answer this question: 8. in 1936 which state became the first to be formed on linguistic basis?
