Each U.S. state has borne witness to an important historical event that has shaped its history — for better or worse. In many cases, the event has had implications beyond that state’s borders, with profound consequences for the nation and, in some cases, the world.

These events include political changes, armed conflict, legal rulings, tragedies, cultural shifts, economic upheavals, ecological episodes, and scientific breakthroughs. But all of them changed the destiny of a particular state.

24/7 Wall St. reviewed state historical information, research sources, and media reports of significant events throughout U.S. history to determine the most important event in the history of each state.
