In September 1966, the Indira Gandhi-led Union Government accepted the demand, and Punjab was trifurcated as per the Punjab Reorganisation Act.Areas in the south of Punjab that spoke the Haryanvi dialect of Hindi formed the new state of Haryana, while the areas that spoke the Pahari dialects were merged to Himachal Pradesh (a Union Territory at the time).
The Government of India was wary of carving out a separate Punjabi language state, because it effectively meant dividing the state along religious lines: Sikhs would form a 60% majority in the resulting Punjabi state.
Fresh from the memory of the violent religion-based partition of India in 1947, the Punjabi Hindus were also concerned about living in a Sikh-majority state.
Examples of Punjabi Hindus include the former Prime ministers of India I. Gujral and Gulzari Lal Nanda and former Indian cricketer Kapil Dev and scientist Hargobind Khorana.
