James K. Polk
The 11th President of the United States was born in 1795 and passed away in 1849; he was a distinguished man named James K. Polk. Historians remember him as a great president who missed opportunities because he stepped down too soon.
Polk had famously promised to serve only one term, and even though he could have easily gotten re-elected, he didn’t participate in the elections. His presidential term lasted from 1845 to 1849, and during that time, Polk managed to win the American-Mexican war and extend U.S. territory, lowered tariffs, and strengthened the executive branch.
