How did baseball evolve from English folk games to a modern sport?

Baseball developed from older bat-and-ball folk games played in Great Britain and Ireland, which were later brought to North America by immigrants. During the 19th century, American clubs codified uniform rules and established professional leagues that shaped the modern game. Over time, the sport expanded internationally, gaining deep popularity in parts of the Americas and East Asia.
