This Day in History — USA President

In 1804, Meriwether Lewis and William Clark launched their historic expedition from St. Louis under President Thomas Jefferson’s orders. Tasked with exploring the Louisiana Territory and finding a route to the Pacific, the Corps of Discovery mapped unknown lands, documented wildlife, and forged relationships with Native American tribes across the frontier.

On May 13, 1846, Congress approved President James K. Polk’s request to declare war on Mexico after escalating border disputes along the Rio Grande. The conflict, driven by Manifest Destiny and territorial ambitions, reshaped North America, expanded U.S. territory westward, and intensified national debates over slavery and American expansion.

On May 8, 1945, Victory in Europe Day marked the end of World War II in Europe after Nazi Germany formally surrendered to the Allied powers. Celebrations erupted worldwide as millions welcomed peace after years of devastation, honoring the sacrifices, courage, and unity that defeated tyranny and restored hope across Europe.

Created by President Franklin D. Roosevelt on May 6, 1935, the Works Progress Administration became a cornerstone of the New Deal during the Great Depression. The WPA employed millions of Americans in public works, infrastructure, and cultural projects, helping restore economic stability, national morale, and hope during one of America’s hardest eras.

On April 28, 1818, the United States and Great Britain formalized the Rush-Bagot Treaty, limiting naval forces on the Great Lakes after the War of 1812. This landmark agreement reduced tensions, prevented an arms race, and helped establish the world’s longest peaceful border, setting a lasting example of diplomacy and disarmament.
