Theodore Roosevelt, the 26th President of the United States, was a dynamic leader, reformer, and conservationist who shaped modern America. Born in 1858 in New York City, Roosevelt overcame childhood illness to become a symbol of strength and vigor. This biography explores his achievements as a Rough Rider in the Spanish-American War, his progressive domestic policies, including trust-busting and labor reforms, and his pioneering conservation efforts that created national parks and protected wildlife. Roosevelt’s “big stick” diplomacy established the United States as a global power. His adventurous spirit, exemplified by expeditions in Africa and South America, cemented his reputation as a larger-than-life figure. This book celebrates his legacy as a visionary leader, environmentalist, and advocate for justice who left an indelible mark on American history.
