While Taylor did his duty fighting Native Americans, he also wanted to protect their lands from white settlers and thought that a strong military presence was the only way to do so.

Before Joe Biden won the 2020 Presidential Election, Donald Trump, the 45th President of the United States, was the oldest U.S. President ever to enter office — Trump was 70 years old at the time of his inauguration.

Trump was born in Queens, New York and is the the fourth of five children born to Frederick C. and Mary MacLeod Trump.  

Prior to being elected as the 45th President of the United States, Trump was best known for being a billionaire real estate mogul and the star of the reality TV series The Apprentice and it’s spin off  The Celebrity Apprentice.

Trump first showed interest in politics in 1999 when he tried to seek the Reform Party’s nomination for the 2000 presidential race, but after a poor showing in the California primary, he withdrew his candidacy. He would go on to flirt with the idea of running for president over the next decade and a half and eventually seriously entered the 2016 presidential election in June 2015.

On January 20, 2021, Joe Biden became the oldest president in United States history at the age of 78. Biden is several decades older than most of the other presidents on this list and nearly a decade older than the previous record-holder Donald Trump.

Biden’s win against one of the most controversial presidents ever, Donald Trump, was hard won. Despite initial dismissing rumors of running in the 2020 Presidential Election, Biden entered the crowded Democratic field in April 2019 and won the party’s nomination a year later.

Although Biden’s win was seen as many as a joyous victory after years of Trump’s presidency, the validity of the election was called into question by Trump and his supporters. Biden’s first few weeks in office have been spent trying to undo Trump’s policies and getting the ongoing COVID-19 pandemic under control.

In addition to serving as the 46th President and 47th Vice President under Barack Obama, Biden spent several decades as a U.S. Senator.

Did You Know?

While serving in the Senate, Joe Biden held a few important positions, including Chair of the Senate Foreign Relations Committee, Chair of the International Narcotics Control Caucus, and Chair of the Senate Judiciary Committee.
