Reading the documents on the rise of Syttende Mai celebrations in North Dakota in 1906, I was more than a little alarmed at the themes and tropes that emerged. In matters of ethnic identity, I am prepared to accept a certain measure of cultural chauvinism, but the remarks of future senator Asle Jorgenson Gronne in Grand Forks went way beyond that. They stereotyped immigrant cultures (including his own!), they invoked white supremacy, and they posed a fossilized model for immigration: We’re here, we got ours, now close the door, we’re done!
