First World War (WWI)
The First World War of 1914–1918 was the bloodiest conflict in Canadian history, taking the lives of nearly 61,000 Canadians. It erased romantic notions of war, introducing slaughter on a massive scale, and instilled a fear of foreign military involvement that would last until the Second World War. The great achievements of Canadian soldiers on battlefields such as Ypres, Vimy and Passchendaele, however, ignited a sense of national pride and a confidence that Canada could stand on its own, apart from the British Empire, on the world stage. The war also deepened the divide between French and English Canada and marked the beginning of widespread state intervention in society and the economy.
