Before diving into the iconic acts that have kept the circus thriving for centuries—or even millennia—let’s take a moment to honor the unsung hero of the ring: cotton candy.
While we can’t trace cotton candy back to ancient Rome, where spectators might have enjoyed it while watching gladiators battle in the Colosseum (though large amphitheater events were referred to as circuses, derived from the Latin word for "circle" [source: Parkinson et al]), this sugary treat made its debut at the 1904 St. Louis World's Fair and quickly became a circus favorite [source: Historic Hudson Valley]. Its inventor, William Morrison, a dentist of all professions, initially named it "Fairy Floss," adding a touch of irony to its history.
Let’s acknowledge that cotton candy, like many enduring circus acts, owes its popularity to clever marketing that sparks public excitement. And speaking of creating buzz, our first entry is a perfect example of how to captivate an audience.
10: Sideshows

The sideshow, a staple of circus culture since the 19th century, once showcased individuals with unique appearances or abilities, often perpetuating harmful stereotypes [source: Victoria and Albert Museum]. Though still present in traveling performances today, the focus has shifted toward empowerment and education. Contemporary sideshows aim to entertain while fostering acceptance and understanding.
Historically, sideshows were fraught with ethical issues. They often displayed individuals from ethnic or racial groups deemed "exotic" by Western standards, as well as those with disabilities or rare physical conditions. To justify these displays, circuses frequently used pseudo-scientific terminology to frame the performers as curiosities.
9: Equestrian Stunts

While many associate the circus with acrobats and lion tamers (don’t worry, we’ll cover those), it might come as a surprise that horses were the original stars of the circus. Phillip Astley, a former cavalry officer, established a riding school in London in 1768 [source: Jando]. His groundbreaking innovation was the circular ring, or "circus," which provided spectators with unobstructed views of equestrian tricks from all angles. Astley’s 42-foot (12.8-meter) ring remains the standard for circuses worldwide [source: Jando].
Astley’s equestrian performances, showcasing daring stunts, quickly drew crowds. By 1782, he expanded his success to Paris, inspiring competitors to emerge [source: Jando]. However, the circus evolved beyond just horse acts. To heighten the excitement, Astley introduced short theatrical sketches between equestrian displays, adding variety to the shows.
8: Acrobats

Acrobats initially appeared as interludes between acts at Astley's circus, combining elements of various performances seen today. While acrobatics have branched into numerous disciplines, gymnastic and tumbling skills have been integral to the circus since its inception.
Given the equestrian focus of British circuses, early acrobats utilized horses as part of their acts. Notably, in 1846, acrobat John H. Glenroy achieved a historic milestone by performing the first-ever somersault on horseback [source: Jando]. (For a fascinating read, explore Glenroy's autobiography, which recounts his circus journey starting at age 7.)
Another branch of early circus acrobatics involved floor performers specializing in tumbling and balancing acts. These performers began infusing humor into their routines, crafting amusing and eccentric characters. Comedy soon became a major attraction, especially with the introduction of clowns to the circus.
7: Clowns

Of course, no circus is complete without performers in colorful makeup cramming into tiny cars or engaging in slapstick humor with rubber chickens. (Is that truly a clown act? If so, let’s hope there’s more depth to it.) As mentioned earlier, early floor acrobats began blending clowning into their routines, giving birth to the circus’s new stars.
While the circus didn’t invent clowns, Philip Astley introduced a vaudeville-style act featuring a character called "Mister Merryman," filled with the expected silliness. However, clowning and pantomimes predate Astley’s contributions [source: Angelo].
Today, clowns are synonymous with the circus. However, not all clowns are the same: the classic "white-face clown" often plays the clever counterpart to the bumbling Auguste, orchestrating humorous mishaps and mischief.
6: Elephants

Elephants have historically been showcased in Western cultures as exotic attractions, drawing crowds eager to marvel at their presence. While they didn’t always perform elaborate tricks or serve as platforms for acrobats, records from as early as 1623 mention elephants touring England in menageries [source: Speaight].
Performing elephants became a circus mainstay around 1820, with acts featuring them picking up coins or tipping their keeper’s hat [source: Speaight]. By the 1870s, choreographed group performances made them a crowd favorite [source: Victoria and Albert Museum]. However, concerns over the welfare of circus elephants have grown, and trainers also faced significant risks. One notable trainer lost his life while attempting to load an elephant onto a train [source: Speaight]. Due to ongoing controversies, Ringling Bros. and Barnum & Bailey announced plans to retire elephant acts by 2018 [source: Wallace].
While we’ll revisit other iconic circus animals, let’s first turn our attention to an even more daring spectacle.
5: Rope Walking

In the early days, tightrope walking was known as "rope dancing," a term chosen to evoke a more sensual experience. This wasn’t just semantics—female performers often captivated audiences by removing petticoats during their acts in the 17th and 18th centuries, adding an element of allure to their performances [source: Speaight]. Quite risqué for the time!
Rope acts predate the modern circus but became a staple of the spectacle. While the high wire, where performers balance on a tightrope high above the ground, is the most well-known, there are two other variations. The slack rope features comedians performing on a loose rope between poles, while the slope wire adds an incline, increasing the challenge and excitement.
If you think rope walking is daring, imagine working with untamed wild cats.
4: Big Cat Acts

Like elephants, big cats such as lions, tigers, and other large felines were often showcased in menageries or traveling shows throughout history. In ancient times, these animals were displayed primarily for eventual slaughter rather than performing tricks. However, by the 19th century, the circus popularized the idea of "taming" these majestic creatures [source: Speaight].
Around 1825, a British menagerie introduced classic tricks that remain synonymous with big cat acts today. Trainers would place their heads in a lion’s mouth or command tigers and lions to leap through hoops. Some circuses even staged elaborate performances, such as a keeper playing Hercules and subduing a lion.
While big cats in the ring continue to amaze audiences, some 19th-century performers experimented with domestic cats in their acts [source: Speaight]. (Unsurprisingly, this trend didn’t last.) If managing cats seems challenging, our next circus act offers a simpler yet equally captivating spectacle.
3: Juggling

While many link juggling to clowns, it’s a timeless circus tradition. In 1820, Ramo Samee, an Indian juggler, gained fame for his four-ball act [source: Speaight]. As circuses grew in popularity, jugglers added more balls, but audiences craved even greater thrills.
This led to the rise of juggling unconventional items. Jugglers began tossing everything from coffee cups to knives. Modern juggling often incorporates athletic feats, such as performing on a unicycle or tightrope, to heighten the excitement.
In Chinese circus traditions, simple juggling wasn’t enough. Performers took it to the next level by juggling while suspended by their hair, an act known as hair hanging. This daring performance is experiencing a resurgence in contemporary circuses, blending acrobatics with juggling [source: Winship].
2: Aerial Acts

The flying trapeze is an iconic part of the circus, but its origins are part of a broader evolution of aerial performances. In the late 19th century, the Roman Rings, used in gymnastics, were combined with a bar to create the trapeze [source: Speaight]. This innovation led to acts like the Iron Jaw, where performers gripped the bar with their teeth, showcasing the versatility of aerial artistry.
Jules Leotard revolutionized the trapeze by introducing a second bar, enabling performers to soar between them. This act debuted in 1859 and was so groundbreaking that a plaque at the Cirque Napoleon commemorates the event [source: Jando]. Leotard also left a lasting legacy with the leotard costume, now synonymous with circus and gymnastics.
1: Ringmaster

No circus is complete without its sharply dressed ringmaster, who announces acts and energizes the crowd. Originally known as the riding master, a nod to the circus’s equestrian roots, this role has remained a vital tradition in both historical and modern circuses.
In modern circuses, ringmasters frequently engage with clowns, but their primary role is to introduce acts to the audience. Historically, ringmasters served as emcees and ensured horses maintained a steady pace for acrobatic performances. This explains their traditional attire of red coats, white pants, and tall boots, reminiscent of equestrian captains. Early ringmasters used whips to signal horses, while clowns often bore the brunt of more direct interactions.
