50 free Westward Expansion trivia questions with answers — history quiz, new questions added Oct 2026.
In less than a century the United States grew from a strip of states along the Atlantic into a nation that reached the Pacific. It happened through bargains with European empires, a war with Mexico, wagon roads worn across plains and mountains, and a rush for gold and farmland. It also came at a terrible cost to the Native nations whose homelands lay in the way. This quiz covers the whole story: the land deals that redrew the borders, the explorers who went ahead, the trails settlers followed and the dangers they met, the fight for Texas and the Southwest, the laws that handed out land, the railroad and the inventions that changed the plains, and the removals, battles and broken treaties that shaped life for American Indians. The questions run from classroom staples to tougher ones for history buffs, so they suit middle school and high school review as well as a trivia night. Every answer comes with a short explanation, and you can play straight through or print the set as a quiz bank.
