There was the Homestead Strike in 1892, during which 9 people died. The Pinkerton Detective Agency, which "handled" the strike for Carnegie, is notorious for violently busting strikes in the 19th century US.
Err, "today" today? Today looks more like May 15 to me.
The 19th century closed on December 31, 1900, right? Do you disagree with that? That the 20th century began on 1/1/1901? Not in dispute?
I would say we're at 124.5 years after its close today, if you really mean today. I suppose if you want to be sloppy and round up we could achieve 125, but technically, we're still, like, 7.5 months away from December 31st.
