After the period when Rome was powerful, Europe did not have a circus tradition. In China there were shows with acrobatic performances, but they did not influence the Western circus, which started to be popular towards the end of the 18th century. In London there were circuses with horse-riding. These were started in 1768 by Philip Astley. A “Royal Circus” was set up in Lambeth, London by John Hughes. Circuses grew in size and had lots of animals. They were a bit like a zoo. They had wild animals such as lions and elephants. In 1793 a circus building was opened in Philadelphia, USA. Circuses became popular in the USA, especially the circus of Dan Rice. In 1840 Thomas Cooke brought his circus with horses from the USA to England. The circus started to become popular in many countries all over the world. The Barnum & Bailey Greatest Show On Earth toured from 1897 to 1902. They showed animal acts and human acts. There were even shows with freaks (people who were physically unusual, e.g. dwarfs and giants). During most of the 20th century this is what circuses were mostly like.
