than changes in practice on the romanisation of indigenous Indian language names. Realignment of the official Indian English name to an alternative local name Aside from changes to the official English spellings of local names there have also been renaming proposals to realign the official name, hence the English name with an alternative local name. Ethnically sensitive examples include the proposals by the Bharatiya Janata Party (1990, 2001) to rename Ahmedabad to Karnavati and Allahabad to Prayagraj, the latter ultimately being officially adopted in 2018. These two proposals are changes from the historically Islamic name to a Hindu native name. These can be represented as a change from Urdu language to Hindi language, but since the two languages are variants of Hindustani the proposal is effectively a cultural and ethno-religious proposal rather than a linguistic one. Adoption of renamed names Official name changes take place quickly if not immediately in official government sources. Adoption may be slower among the media in India and abroad, and among Indian authors. Important examples States Travancore-Cochin → Kerala (1st November, 1956).
