In 1917 the IRB was renamed the IRA and in 1919, the fighting started. By 1921, the IRA had beaten the Royal Irish Constabulary (RIC) and Ireland had no police forces. In London, the British government began to debate about Ireland's rule. The war went on until 1922 when Irish Sinn Féin leaders and British MPs made a peace treaty (called the Anglo-Irish Treaty). This treaty created the Irish Free State this meant that Ireland was made its own independent country. The treaty gave all the same rights to the Irish government as that of the Canadian government
