How did the Irish influence horse racing?

Answer 1

The Irish invented horseracing. It began as a game of how fast can your new horse run but then grew. When the Irish immigrated over to the United States, the sport became nation wide. The sport was especially popular in Kentucky, and thus the Kentucky Derby was the name of the game. Heres a good site http://www.ibiblio.org/fiddlers/Playingponies2.htm
