In the 17th century, soldiers from the Austro Hungarian Empire settled in New France. Numbers increased following the passing of the Staatsgrundgesetz (constitutional law) in 1867 which allowed free migration from the empire for civilians. Emigration to Canada increased throughout the late 19th century and into the early 20th, until this was tightened in 1914 at the onset of World War I.[2]
