President Trump focused on his own hardships since taking office during his commencement address Wednesday at the United States Coast Guard Academy, saying, "No politician in history — and I say this with great surety — has been treated worse or more unfairly."

History is very long, and despite Trump's "surety," from the Roman Emperor Caracalla, who was fatally stabbed by one of his soldiers while urinating along a roadside, to Nelson Mandela, who was labeled a terrorist and spent 27 years in prison, the past is replete with stories of politicians who had it rougher than Trump.

But, perhaps the president meant to say he was being treated more unfairly than any politician in U.S. history. But even by that standard, most would agree the following American leaders and lawmakers had it worse than Trump.
