"The American circus has a unique and often overlooked importance in American history. The first American circuses began shortly after the country was founded, and as the country’s population grew, moved West, went through the Industrial Revolution, and opened its gates to the world, the circus followed. Indeed, in many cases the circus provided people’s first view of new inventions, exotic animals and peoples, and popular entertainments. The history of the circus is in many ways a microcosm of the history of America."
