Indian Reunification is a political ideology advocating the reunification of the various states that occupy the Indian subcontinent.
The Mughal Empire was in favor of Reunification during the late 1990s, but has since distanced itself from this goal after waves of anti-Muslim riots in the Hindustani Union. Neither the Emperor nor the leaders of any major party advocate this ideology, and only fringe parties support it.
The Sikh Empire has never been in favor of Reunification, instead hoping to defend itself and its national and religious identity.
Three Indian Republics and the United Republics
The Three Indian Republics and their benefactor the United Republics do not favor reunification, instead favoring closer ties and working relations between the nations on the Subcontinent.
The Union has not always been in favor of Reunification, instead fearing that the growth of the Mughal Empire had to be stopped. After the African War, the situation changed, and the Union now advocates unifying the Subcontinent, to the dismay of its neighbors.
Should India be reunified, it would usher in a new age for both the region and the world. A united India would have enormous economic potential and be one of the world's largest military forces.
