Barnum did not enter the circus Business until he was 60 years old. In Delavan, Wisconsin in 1870 with william Cameron Coup, he established "P. T. Barnum's Grand Traveling Museum, Menagerie, Caravan & Hippodrome," a traveling circus, menagerie and museum of "freaks." It went through various names: "P.T. Barnum's Travelling World's Fair, Great Roman Hippodrome and Greatest Show On Earth," and after an 1881 merger with James Bailey and James L. Hutchinson, "P.T. Barnum's Greatest Show On Earth, And The Great London Circus, Sanger's Royal British Menagerie and The Grand International Allied Shows United," soon shortened to "Barnum & Bailey's." This entertainment phenomenon was the first circus to display three rings, which made it the largest circus the world had ever seen. The show's first primary attraction was Jumbo, an African elephant he purchased in 1882 from the London Zoo. The Barnum and Bailey Circus still contained acts similar to his Traveling Menagerie: acrobats, freak shows, and the world-famous General Tom Thumb. Despite more fires, train disasters, and other setbacks, Barnum plowed ahead, aided by circus professionals who ran the daily operations. He and Bailey split up again in 1885, but came back together in 1888 with the "Barnum & Bailey Greatest Show On Earth," later "Barnum & Bailey Circus," which toured the world.
