When Ringling Bros. and Barnum & Bailey wrapped its final circus tour, "Out of This World!" at NYCB Live's Nassau Veterans Memorial Coliseum on May 21, 2017, the curtain fell on decades of iconic entertainment marked with much nostalgia and lingering criticism. Here's a look at key moments in the circus' history.

P.T. Barnum, founder of one of the forerunners to Ringling Bros. and Barnum & Bailey, creates a museum of oddities in Manhattan with displays including a flea circus, ventriloquists. In later years, he added appearances by Siamese twins Chang and Eng, Grizzly Adams’ trained bears and 25-inch-tall General Tom Thumb.

P.T. Barnum’s Great Traveling Museum, Menagerie, Caravan and Hippodrome debuts under a tent in Brooklyn. (Barnum, pictured, lent his name to an existing circus.) This is the year cited for the founding of Ringling Bros. and Barnum & Bailey Circus. It wasn't until a decade later that Barnum teamed up with well-known circus man James Bailey, creating yet another forerunner to what would become Ringling Bros. and Barnum & Bailey Circus.

The showman P. T. Barnum dies, leaving his circus empire worth $5 million dollars. Bailey purchased the circus, then died in 1906. The next year, the Ringling Brothers, operators of an independent circus, purchased the Barnum & Bailey show, which the brothers ran separately from the Ringling circus until 1919, when the two shows were combined.
