Nordic languages and Hindu-Urdu are great examples of how political language is. The reason Urdu was made a separate language was because of political reasons of the Mughals. Similarly, I believe Norwegians gave a separate legal status to Norwegian to make it distinct from Danish, as a mark of defiance to Danish colonial rule of the past.
TO be fair Hindi, even though it grew more organically was given a formal status of national language by the predominantly Northern Indian Congress government post-independence to use it as an instrument to exert central political influence on the rest of the country, rather unfairly. At the time of India's independence, there were far more Tamil and Bengali speakers (not just native) than Hindi, but the central government forced Hindi to the rest of the country which did lead to a lot of understandable backlash, primarily in the South, which is why they dare not make it the official language of the country.
