The KKK is most infamous for violently terrorizing African Americans. But in the 1920s its hatred also had other targets, especially outside the South. This version of the KKK, known as the Second Ku Klux Klan, harassed Catholics, Jews and immigrants – including students and staff at Catholic universities like Dayton, where I am a historian of American religion.

It was Dec. 19, 1923 – 100 years ago. The first day of Christmas break at the University of Dayton, with fewer than 40 students still on campus.

At 10:30 p.m., the quiet was shattered by a series of explosions, as 12 bombs went off throughout campus. Frightened students discovered that, while damage was minimal, there was an eight-foot burning cross on the edge of campus. Running to tear it down, they were confronted by several hundred Klansmen screaming threats from 40 to 50 cars.

It wasn’t the first time Dayton’s residents had endured terror from the Ku Klux Klan. Hundreds of neighbors poured out of their houses and charged at the hooded invaders. The Klansmen sped away, and the students and others extinguished the fire and tore down the cross.

All of this is the focus of my 2013 article, “Hearing the Silence.”

The Second Ku Klux Klan
The KKK emerged in the South in the years immediately after the Civil War. Its goal was to use whatever means necessary – including a great deal of murderous violence – to force newly freed African Americans into conditions close to slavery.

Having succeeded, the original Klan all but disappeared by the end of the 19th century. But in the wake of the blockbuster film “Birth of a Nation” – which celebrated the original KKK as having “redeemed” the defeated South – the organization was reborn in Georgia in 1915.

This second KKK only attracted a few hundred members over the next few years. But it exploded upon the national scene in the early 1920s, thanks to anxieties about immigration, race and communism. In fact, the white-robed Klansmen with their fiery crosses – a symbol borrowed from “Birth of a Nation” – very soon attracted between 1 million and 5 million members.
