Less concrete changes include the growing assertiveness of the Dominions within the British Empire. Battles such as Gallipoli for Australia and New Zealand,[156] and Vimy Ridge for Canada led to increased national pride and a greater reluctance to remain subordinate to the United Kingdom.[14] These battles were often portrayed favourably in these nations' propaganda as symbolic of their power during the war.[14][156] The war released pent-up indigenous nationalism, as populations tried to take advantage of the precedent set by the introduction of self-determination in eastern Europe. Britain was to face unrest in Ireland (1919–21), India (1919), Egypt (1919–23), Palestine (1920–21) and Iraq (1920) at a time when they were supposed to be demilitarising.[13] Nevertheless, Britain's only territorial loss came in Ireland,[13] where the delay in finding a resolution to the home rule issue, along with the 1916 Easter Rising and a failed attempt to introduce conscription in Ireland, increased support for separatist radicals, and led indirectly to the outbreak of the Irish War of Independence in 1919.[157]
