Under Griffith's policy, Collins and other advocates of the "physical-force" approach to independence gained the cooperation of Sinn Féin, while agreeing to disagree with Griffith's moderate ideas of a dual monarchy solution based on the Hungarian model. The British government and mainstream Irish media had wrongly blamed Sinn Féin for the Rising. This attracted Rising participants to join the organisation in order to exploit the reputation with which such British propaganda had imbued the organisation. By October 1917 Collins had risen to become a member of the executive of Sinn Féin and director of organisation for the Irish Volunteers. Éamon de Valera, another veteran of 1916, stood for the presidency of Sinn Féin against Griffith, who stepped aside and supported de Valera's presidency.
