This doctrine mentions that particular state belongs to majority linguistic group inhabiting it or constitutes an exclusive "homeland" for regional language speakers. The doctrine is majorly popular in cities. In the struggle for the appropriation of economic resources and economic opportunities, recourse was often taken to communalism, casteism and nepotism.

In similar way, language loyalty and regionalism was and is still used to systematically exclude the "outsiders". This doctrine was profoundly utilized in big metros like Mumbai (Marathi) [Earlier Bombay], Bangalore (Kannada), Kolkata (Bengali), etc.

“Mulki rule” provided in article 371(D) of Indian constitution safeguards the rights of local people in employment and education and was created after agitation in the state of Andhra Pradesh. This is an example of Sons of soil doctrine, but this was provided only in Group C and D services.
