Presidential inaugurations mark some of the most defining moments in American history, allowing presidents to build traditions and reinvigorate the American people.
Some inaugurations make history, while others are remembered for hilarious blunders and even brawls.
Before President-elect Donald Trump is sworn in for the second time on Monday, here are some of the most important Inauguration Day moments in American history.

No traditional story is complete without its origins. President George Washington delivered his first inaugural address on April 30, 1789, just two weeks after Congress unanimously elected him to lead the nation.

In his 10-minute speech, he referred to the "divine blessing" of America's founding and expressed gratitude to the "merciful parents of mankind" for their thoughtful efforts toward the founding and unity of the American people.
After President Andrew Jackson was first inaugurated in 1829, approximately 20,000 supporters participated in celebrations around the White House.
However, the mob soon became rowdy, fights broke out and furniture was destroyed. Jackson eventually escaped through a window to the safety of a nearby hotel, according to the National Archives.

On a freezing day in March 1841, President William Henry Harrison delivered his inaugural address. He refused to wear a coat and rode to and from the inauguration on an open horse. His speech was also the longest in American history, with Harrison's speech lasting more than two hours.

A few weeks after Inauguration Day, Harrison came down with a cold that developed into pneumonia and died on April 4, less than a month after taking office.
President Franklin Roosevelt was first sworn in in 1933 during the Great Depression.
In his first inaugural address, he delivered a line now known to nearly all Americans, telling people: "The only thing we have to fear is fear itself."

Roosevelt's steadfast leadership got Americans through the Great Depression and World War II.
When President John F. Kennedy was inaugurated on January 20, 1961, he also uttered a quote that has gone down in the American pantheon.
“Ask not what your country can do for you, ask what you can do for your country,” he urged.

Kennedy's words led America to the moon and back, and to this day, polls rank him as the most popular new president.
President Barack Obama's first inauguration was notable not only because he was the first black American to become president, but also because of the historical quirk that he had to be sworn in twice.
Obama spoke briefly with Supreme Court Chief Justice John Roberts as Roberts was sworn in. As a result, Roberts slipped and said: "I will faithfully discharge the duties of President of the United States."

Obama later repeated the phrase, but it was incorrect. The correct wording of the oath in the Constitution is "I will faithfully discharge the offices of President of the United States."
Although the ceremony continued, Obama and Roberts met again at the White House the next day to properly administer the oath.
