The Wikipedia article of the day for June 29, 2021 is Berlin to Kitchener name change.
Berlin, Ontario, changed its name to Kitchener by referendum in May and June 1916. Named in 1833 after the capital of Prussia and later the German Empire, Berlin was heavily German-Canadian, and its residents enjoyed a blend of British and German culture. The name Berlin became unsavoury for residents after Great Britain and Canada’s entry into the First World War, as German Canadians experienced increasing anti-German sentiment. In a vote characterized by intimidation and high voter turnout, the 19 May 1916 referendum on changing the name narrowly passed; a second vote to choose the new name saw low turnout. The vote settled on Kitchener, named for British field marshal War Secretary Lord Kitchener. The city was officially renamed on 1 September 1916. After the war, the city experienced a decline in its German culture with German Canadians being culturally assimilated into the broader Canadian identity.
