The States Reorganisation Act of 1956 was a major reform of the boundaries of India's states and territories, organizing them along linguistic lines. It abolishedthe existing distinction among Part A, Part B, Part C, and Part D states. The distinction between Part A and Part B states was removed and they came to be known as "states". It reduced the number of States in the country from 27 to 14. A new type of entity, the Union Territory was formed.
