Theodore Roosevelt was a man who couldn't sit still for long. He was born on October 27, 1858, in New York City, into a family with a lot of money. As a kid, he had asthma, but he didn't let that stop him - he found ways to stay active by boxing, hiking, and rowing. This active lifestyle became a big part of who he was, and he lived by a philosophy he called "the strenuous life".

He finished school at Harvard back in 1880 and then got into the New York Assembly when he was just 23 years old. He made a name for himself by speaking out against corruption. But his life took a tough turn in February 1884 when his wife Alice and his mom died on the same day. He was really struggling with his grief, so he decided to head out to the Dakota Territory to try his hand at ranching, hunting, and even worked as a deputy sheriff. His time out West ended up giving him a cowboy image that stuck with him forever. A couple of years later, in 1886, he married his old friend Edith Carow, and they went on to have six kids together at their home on Long Island, called Sagamore Hill.

After heading back east, he took on a few different roles, including working as the U.S. Civil Service Commissioner and the Police Commissioner for New York City. What's really interesting is that he didn't just sit behind a desk - he actually went out on night beats to check in with his officers and see how things were going. Later on, he worked as the Assistant Secretary of the Navy under William McKinley, and during that time, he helped get everything ready for a potential war with Spain. But in 1898, he decided to resign from that position and do something a bit more hands-on. He put together a group of volunteers, known as the 1st Volunteer Cavalry, or the Rough Riders, and led them into battle near Santiago, where they fought their way up Kettle Hill. The newspapers ate it up, and soon he was being hailed as a hero.

Theodore Roosevelt's rise to fame ultimately led him to win the governorship of New York in 1898, and just two years later, in 1900, he became the vice president. But his time in this role was short-lived, as a dramatic turn of events changed the course of his life. On September 6, 1901, while attending an event in Buffalo, President McKinley was shot by Leon Czolgosz. This tragic incident led to McKinley's death on September 14, 1901. As a result, Roosevelt took the oath of office on the same day, becoming the youngest president in American history at just 42 years old.

Theodore Roosevelt had a plan, which he called the Square Deal, and he believed that the government should make sure that businesses and workers were treated fairly. In 1902, he took on the big railroad companies by suing the Northern Securities railroad trust, and this was just the start of many lawsuits against companies that had too much power. He was able to get two important laws passed: the Elkins Act in 1903 and the Hepburn Act in 1906, which helped to regulate the railroads. Then, after Upton Sinclair wrote his book The Jungle, which exposed some really bad things that were happening in the food industry, Roosevelt signed two new laws in 1906: the Pure Food and Drug Act and the Meat Inspection Act, which were meant to keep people safe from bad food and medicine.

He left a lasting mark on the environment, and that's really something to be proud of. Working together with Gifford Pinchot, they made sure to protect a huge amount of land - we're talking about 230 million acres. They also created five amazing national parks, 18 national monuments like Devils Tower, and 150 national forests. What's really important is that he believed public lands were like a trust, something to be held onto for the people who come after us.

When he was dealing with other countries, he used a mix of being gentle and being strong. For example, he helped end the Russo-Japanese War by bringing everyone together in Portsmouth, New Hampshire, in 1905. This was a big deal, and he was awarded the Nobel Peace Prize in 1906 - the first American to ever get this honor. He also helped Panama become its own country, separate from Colombia, in 1903, and he made sure the Panama Canal got built. His approach to working with other countries was simple: be nice, but also be strong and prepared to take action, which he summed up as "speak softly and carry a big stick."

Theodore Roosevelt stepped down in 1909, making way for William Howard Taft to take the reins. However, their relationship soon took a turn for the worse, and they found themselves at odds with each other. In 1912, Roosevelt decided to run for office again, this time as the nominee for the Progressive Bull Moose Party. Tragedy struck on October 14, 1912, when he was shot in Milwaukee by a man named John Schrank. Despite the severity of his injury, Roosevelt showed remarkable resilience and delivered an 84-minute speech with the bullet still lodged in his chest, before finally seeking medical attention at a hospital. The Republican party's division ultimately led to the election of Woodrow Wilson, a Democrat, who went on to become the President of the United States.

Theodore Roosevelt's health was badly damaged after he went on a big adventure down Brazil's River of Doubt in 1913 and 1914. For the rest of his life, he was pretty sick, but he still managed to write a lot and tried to convince Americans to join World War I. Sadly, he passed away at his home in Sagamore Hill on January 6, 1919.

Roosevelt was contradictory, an aristocrat who praised the frontier, a warrior who won a peace prize, a reformer who loved power. That restless mix still defines his place in American memory.
