which commission was appointed for the creation of new states on the basis of language
States Reorganisation Act, 1956 The States Reorganisation Commission was preceded by the Linguistic Provinces Commission (aka Dhar Commission), which was set up in June 1948. Prime Minister Jawaharlal Nehru appointed the States Reorganisation Commission in December 1953, with the remit to reorganise the Indian states. The new commission was headed by the retired Chief Justice of the Supreme Court, Fazal Ali; its other two members were H. N. Kunzru and K. M. Panikkar. The efforts of the commission were overseen by Govind Ballabh Pant, who served as the Home Minister from December 1954.
Northwest Ordinance The most significant intended purpose of this legislation was its mandate for the creation of new states from the region. It provided that at least three but not more than five states would be established in the territory, and that once such a state achieved a population of 60,000 it would be admitted into representation in the Continental Congress on an equal footing with the original thirteen states. The first state created from the Northwest Territory was Ohio, in 1803, at which time the remainder was renamed Indiana Territory. The other four states were Indiana, Illinois, Michigan, and Wisconsin. A portion (about a third) of what later became the state of Minnesota was also part of the territory.
