Diarchy

noun

/ˈdaɪɑːki/

A form of government in which power is shared between two authorities; in British India, the system introduced by the Government of India Act 1919 that divided provincial subjects into "reserved" (under the Governor) and "transferred" (under elected Indian ministers).

✍️ Usage in a UPSC answer

The Montagu-Chelmsford reforms introduced diarchy in the provinces, but by entrusting "transferred" subjects to elected ministers while reserving the vital portfolios for an unaccountable executive, the scheme bred administrative friction rather than genuine responsible government.
