United States History On This Date: April 22nd

1889 — Oklahoma Land Run

At precisely noon, a gunshot signaled the opening of two million acres of former Indian Territory to white settlement. Tens of thousands surged forward on horseback, wagons, and trains to stake claims in a chaotic scramble that became one of the most dramatic land rushes in American history. The event accelerated the displacement of Native peoples and laid the foundation for rapid settlement and the eventual creation of the state of Oklahoma, leaving a complex legacy of opportunity and dispossession.

1970 — First Earth Day

Millions of Americans participated in rallies, teach‑ins, and demonstrations focused on pollution, conservation, and environmental protection. Organized by Senator Gaylord Nelson and powered by student activism, Earth Day marked a turning point in public awareness of ecological issues. Its success helped spur the creation of the Environmental Protection Agency and landmark legislation including the Clean Air Act, Clean Water Act, and Endangered Species Act. The movement reshaped national environmental policy and remains a defining moment in modern civic activism.

1864 — Congress Authorizes the Motto “In God We Trust”

Amid the turmoil of the Civil War, Congress approved legislation allowing the phrase “In God We Trust” to appear on certain U.S. coins. The motto reflected rising wartime religious sentiment and a desire to express national unity through shared moral language. Over time, its use expanded to additional denominations, and in 1956 it became the official national motto. Today it appears on all U.S. currency and remains a familiar symbol of American civic identity and cultural debate.

1993 — End of the Waco Siege

After a 51‑day standoff between federal agents and the Branch Davidians, an attempted forced entry led to a catastrophic fire that engulfed the compound. More than 70 people died, including leader David Koresh. The tragedy sparked intense debate over federal law‑enforcement tactics, influenced later extremist movements, and remains one of the most controversial episodes in modern American history. Its legacy continues to shape discussions of government power, civil liberties, and the limits of federal intervention.
