Less concrete changes include the growing assertiveness of the Dominions within the British Empire. Battles such as Gallipoli for Australia and New Zealand, and Vimy Ridge for Canada led to increased national pride and a greater reluctance to remain subordinate to London. These battles were often portrayed favourably in these nations' propaganda as symbolic of their power during the war. 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. Nevertheless, Britain's only territorial loss came in Ireland, 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.
