The First World War constitutes a point in New York's history when its identity was challenged, recast and reinforced. Its position as a financial centre meant that its role in the conflict was realised sooner than elsewhere in the United States. This book uses archives, newspaper reports, leaflets and the ethnic press to explore how the city responded to its role in the War, from the outbreak in August 1914, through the official entry of the US in to the war in 1917, and after the cessation of hostilities in memorials to the conflict.
