Some of the most memorable moments in US history have occurred on Inauguration Day.

Inaugurations of U.S. presidents are significant events that enable them to establish customs and rejuvenate the nation.

While some inaugurations are remembered for historical significance, others are infamous for humorous mistakes and even physical altercations.

On Monday, as President-elect Donald Trump is sworn into office for a second term, here are some of the most significant Inauguration Day moments in U.S. history.

George Washington's first inaugural address

The first inaugural address was delivered by President George Washington on April 30, 1789, two weeks after his unanimous election as the nation's leader.

The speech he gave in 10 minutes acknowledged the "divine blessing" of the country's establishment, expressing gratitude to "the benevolent source of the human race" for the discussions that resulted in the formation and unity of the American people.

Andrew Jackson's White House mob

During his first inauguration in 1829, President Andrew Jackson was surrounded by approximately 20,000 of his supporters during a celebration held near the White House.

Fights broke out and furniture was destroyed as the mob grew rowdy, ultimately leading Jackson to flee out a window to a nearby hotel, according to the National Archives.

To get the crowd to leave the building, the White House staff resorted to filling bathtubs with whiskey and orange juice outside the building.

William Henry Harrison's only inauguration

In March 1841, President William Henry Harrison delivered his inaugural address while wearing only a hat and coatless. Despite the cold weather, he rode to and from the ceremony on horseback. His speech lasted over two hours, making it the longest in U.S. history.

On April 4, just a month after being inaugurated, Harrison passed away due to pneumonia, which had started as a simple cold several weeks prior.

Franklin D. Roosevelt's first inauguration

In 1933, President Franklin D. Roosevelt was inaugurated during the Great Depression.

In his first inaugural address, he famously said, "The only thing we have to fear is fear itself."

Through both the Great Depression and World War II, Americans would persevere under Roosevelt's unwavering leadership.

John F. Kennedy's inaugural address

On January 20, 1961, President John F. Kennedy delivered a line that would become iconic in American history.

He urged to ask not what the country can do for you, but what you can do for the country.

To this day, Kennedy's words continue to inspire and lead the country, and polls consistently rank him as the most beloved recent president.

Barack Obama's first inaugural address

Notably, President Barack Obama's first inauguration was significant due to two reasons: firstly, he was the first Black American to hold the presidency, and secondly, he had to be sworn in twice due to a historical quirk.

During the swearing-in ceremony, Obama and Supreme Court Chief Justice John Roberts exchanged brief words. Due to this interaction, Roberts made a mistake and incorrectly stated, "I will faithfully execute the office of president to the United States."

Obama incorrectly repeated the phrasing of the oath's wording in the Constitution, which is "That I will faithfully execute the office of President of the United States."

The following day, Obama and Roberts met at the White House to administer the oath correctly.
