Which era of baseball did Ruth's home run surge help usher in?

Ruth's home-run surge helped usher in baseball's live-ball era. The period began around 1920, when rule and playing-condition changes produced a dramatic rise in scoring, batting power, and home runs.

Before then, baseball was commonly described as the dead-ball era. Pitchers could scuff or alter the ball, and a single ball was often used until it became dirty or damaged. In 1920, rules restricting those practices and requiring more frequent replacement of damaged balls helped make offensive production more consistent.

Ruth became the era's defining figure. In 1920, he hit 54 home runs, nearly tripling George Sisler's American League-leading total of 19 and surpassing the entire home-run output of many teams. His example encouraged players to pursue power hitting as a central offensive strategy.

The live-ball era was not created by Ruth alone: rule changes, cleaner balls, and evolving tactics all mattered. But his unprecedented production made the home run baseball's signature spectacle and helped drive the sport's surge in popularity.
