Historically it has been very hard to change the structure of caste politics in India. More recently however, there has been a flux in caste politics, mainly caused by economic liberalisation in India. Contemporary India has seen the influence of caste start to decline. This is partly due to the spread of education to all castes which has had a democratising effect on the political system. However, this "equalising" of the playing field has not been without controversy. The Mandal Commission and its quotas system has been a particularly sensitive issue.
