The mountain had been colloquially referred to as Mount McKinley since 1896 and had clearly achieved widespread usage by this article’s publication in 1916, becoming the official name one year later in 1917. But indigenous Alaskans had long called it Mount Denali and never stopped doing so. Last September, President Obama announced that the name would once again officially become Mount Denali, in accordance with the wishes of most native Alaskans.
As was to be expected in this day and age, Obama’s set of a firestorm of controversy, with Republicans claiming this was political correctness gone amok and an intentional attempt to undermine a mountain named after a Republican president. Donald Trump has vowed to change the name back to McKinley if elected president.
Another notable tidbit from that article: the reference to “James Wickersham, the Delegate from Alaska in Congress.” Alaska didn’t become a state until 1959, so back in 1916 they had a delegate much as the District of Columbia or Puerto Rico does today.
