The Golden Age of Baseball, or Baseball's Golden Era, is the period from about 1920 to 1960. The golden era is the time period immediately following the dead-ball era (before World War I) but prior to what is now called the modern era. There is no exact timeframe in any of these eras. MLB considers the post World War II era to be the beginning of the modern age, which places the golden era between the end of World War I and the end of World War II.
