With Occupy Wall Street gaining traction and the country at large seeing greater inequality than ever, it's time to look back on what happened in the Roaring 20s.

During this period anarchists and socialists held protests on Wall Street out of a similar sense of frustration and rage at the banking system. The movement culminated in what was known as the greatest act of terrorism on American soil: the 1920 bombing outside J.P. Morgan and Company.

Thirty eight people were killed when the horse and wagon bomb went off at noon on Sept 16, 1920. The perpetrators, thought to be anarchists, were never caught, but their exploits and the aftermath were captured by photographers.
