Explanation:

 The region was given the name Uttaranchal by the Bharatiya Janata Party led union government and Uttarakhand state government when they started a new round of state reorganisation in 1998. Chosen for its allegedly less separatist connotations, the name change generated enormous controversy among many activists for a separate state who saw it as a political act.The name Uttarakhand remained popular in the region, even while Uttaranchal was promulgated through official usage.

In August 2006, Union Council of Ministers assented to the demands of the Uttaranchal Legislative Assembly and leading members of the Uttarakhand statehood movement to rename Uttaranchal state as Uttarakhand. Legislation to that effect was passed by the Uttaranchal Legislative Assembly in October 2006, and the Union Council of Ministers brought in the bill in the winter session of Parliament. The bill was passed by Parliament and signed into law by then President A. P. J. Abdul Kalam in December 2006, and since 1 January 2007 the state has been known as Uttarakhand.
