List of Diwans of Travancore

The Diwan or Dewan of Travancore was the head of government of Travancore in the nineteenth and twentieth centuries, serving at the pleasure of the Maharaja, corresponding to a prime minister, and consisting in the formal titles Valiya Sarvadhikaryakar and Dalawa until the insurrection of Velu Thampi Dalawa and administrative reforms of John Munro. Post-Munro, the title of Dalawa, which remained formally the highest ranking established office, though administratively impotent, was revived as a sinecure to sideline Raman Menon and remove him from the Diwanship. The office of Diwan existed until 1948, when it gave way to the office of Prime Minister of Travancore.
