When did the anzac war finish?
The term Anzac does not refer to a war. The word Anzac stands for the Australian and New Zealand Army Corps.
There was no war on ANZAC Day. ANZAC Day commemorates Australian soldiers in all conflicts, but usually World War I. The main battleground commemorated is Gallipoli, where ANZAC (Australian New Zealand Army Corps) troops were defeated by the Turks but fought bravely despite bad organisation from the higher-ups.
