The US was formed a long time ago in human terms.
The Brits and others will scoff at the notion citing 1000 years+ of history. But that doesn't mean much,
anything that happened before your Grandparents were born doesn't affect you any more than if it
happened 1000 years ago.
Anyway, sometimes I have trouble connecting events in the right time frame relationship, especially
the 1800s vs the 1900s. I found these two photographs that tie them together.
A young Teddy Roosevelt, first POTUS of the 1900s, watches Abraham Lincoln funeral cortège in 1865.
And Times Square, NY, NY, over 70 years. Been a whole lot of shakin' goin' on.
