Explanation:

 The emergence of Asom Gana Parishad (AGP) in 1985 is a significant political development of the North-eastern region in particular and in the country in general It was formed just
before the Assam Legislative Assembly elections held in December 1985. By securing 63 seats in the 126- member Assembly, the AGP grabbed power in Assam defeating the Indian National Congress (I) which could secure only 25 seats. Although, it may seen that the AGP is the result of anti-foreigner movement (1979-85), its origin may be traced back even earlier to this.
