The Australian and New Zealand Army Corps (abbreviated as ANZAC) was a First World War army corps of the British Army’s Mediterranean Expeditionary Force. It was formed in Egypt in December 1914, and operated most famously during the bloody Gallipoli campaign.

Observed on 25 April each year, Anzac Day was originally devised to honour the members of the ANZACs who served in the Gallipoli Campaign. Today its is a national day of remembrance in Australia and New Zealand that commemorates all Australians and New Zealanders “who served and died in all wars, conflicts, and peacekeeping operations” and “the contribution and suffering of all those who have served”.
