<P> Less concrete changes include the growing assertiveness of Commonwealth nations . 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 Britain, leading to the growth of diplomatic autonomy in the 1920s . These battles were often decorated in propaganda in these nations as symbolic of their power during the war . Colonies such as the British Raj (India) and Nigeria also became increasingly assertive because of their participation in the war . The populations in these countries became increasingly aware of their own power and Britain's fragility . </P> <P> In Ireland, the delay in finding a resolution to the home rule issue, partly caused by the war, as well as the 1916 Easter Rising and a failed attempt to introduce conscription in Ireland, increased support for separatist radicals . This led indirectly to the outbreak of the Irish War of Independence in 1919 . The creation of the Irish Free State that followed this conflict in effect represented a territorial loss for Britain that was all but equal to the loss sustained by Germany, (and furthermore, compared to Germany, a much greater loss in terms of its ratio to the country's prewar territory). Despite this, the Irish Free State remained a dominion within the British Empire . </P> <P> After World War I women gained the right to vote as, during the war, they had had to fill - in for what were previously categorised as "men's jobs", thus showing the government that women were not as weak and incompetent as they thought . Also, there were several significant developments in medicine and technology as the injured had to be cared for and there were several new illnesses that medicine had to deal with . </P> <P> While disillusioned by the war, it having not achieved the high ideals promised by President Woodrow Wilson, American commercial interests did finance Europe's rebuilding and reparation efforts in Germany, at least until the onset of the Great Depression . American opinion on the propriety of providing aid to Germans and Austrians was split, as evidenced by an exchange of correspondence between Edgar Gott, an executive with The Boeing Company and Charles Osner, chairman of the Committee for the Relief of Destitute Women and Children in Germany and Austria . Gott argued that relief should first go to citizens of countries that had suffered at the hands of the Central Powers, while Osner made an appeal for a more universal application of humanitarian ideals . The American economic influence allowed the Great Depression to start a domino effect, pulling Europe in as well . </P>
