During the political events of 1863 in Greece, following the revolution which led to the eviction of Otto and the enthronement of George I, Vikelas led fundraising efforts in support of the provisional government. He also wrote letters to the main newspapers of the time to demand that Greece's rights be respected. He became definitively known in the British intellectual world in 1866 when he contacted authors and academics to gain their support for the Cretan cause during the Cretan Revolt of 1866-1867, for which he raised more fundraising.
