“Phantom-like hosts of the Ku Klux Klan spread their white robe over the most historic thoroughfare yesterday in one of the greatest demonstrations the city has ever seen.” So read The Washington Post on the morning of August 9th , 1925. On the previous afternoon, the nation’s capital bore witness to the largest Klan march in the city’s history as tens of thousands of robed Klansmen marched down Pennsylvania Avenue towards the Washington monument, most of them feeling no need to wear a mask.
It was the roaring '20s and radio was taking off. Americans were tuning-in in droves for news, opera, popular music and sports. No other medium offered the ability to reach so many people instantaneously. Advertisers took note.
So, too, did the resurgent Ku Klux Klan, which was interested in its own sort of advertising: promoting a unique brand of “patriotism” founded upon white privilege and intolerance for blacks, Catholics, Jews and immigrants amongst others. The Klan's foray into broadcasting is still felt in Washington to this day.
