Which statement is not accurate according to the passage?

The movement against making Hindi the official language primarily occurred in Southern India.

The initial emergence of separatist sentiments materialized in Nagaland, followed by Mizoram, where fervent movements advocated for detachment from the Indian nation. Concurrently, in the southern landscape, certain factions associated with the Dravidian movement flirted briefly with the idea of forming a distinct country.
After India's independence widespread movements sprouted in various corners of the nation, all advocating for the establishment of linguistic States. This movement's impact was felt in the present-day regions of Andhra Pradesh, Karnataka, Maharashtra, and Gujarat. A similar pattern manifested in the southern domain, particularly in Tamil Nadu, where protests against the imposition of Hindi as the official national language took root. Contrastingly, the northern landscape experienced potent pro-Hindi demonstrations that urgently demanded Hindi's immediate recognition as the official language.
