Breaking or b-boying, commonly known by its exonym as breakdancing, was created in the South Bronx, New York City during the early 1970s. It is the first hip-hop dance style. At the time of its creation, it was the only hip-hop dance style because Afrika Bambaataa classified it as one of the five pillars of hip-hop culture along with MCing (rapping), DJing (turntablism), graffiti writing (bombing), and knowledge. Though African Americans created breaking, Puerto Ricans maintained its growth and development when it was considered a fad in the late 1970s. In a 2001 interview Richard "Crazy Legs" Colón, the president of Rock Steady Crew, commented on how Puerto Ricans contributed to breaking: "I think the difference is when the brothas first started doing and it was at its infancy they weren't doing acrobatic moves. That didn't come into play until more Puerto Ricans got involved in the mid 70s. We then took the dance, evolved it and kept it alive. In '79 I was getting dissed. I would go into a dance and I would get dissed by a lot of brothas who would ask 'Why y'all still doing that dance? That's played out'. By 79, there were very few African American brothas that was doing this... We always maintained the flava. It was like a changing of the guard and all we did was add more flava to something that already existed." Breaking includes four foundational dances: toprock, footwork-oriented steps performed while standing up; downrock, footwork performed with both hands and feet on the floor; freezes, stylish poses done on your hands; and power moves, complex and impressive acrobatic moves. Transitions from toprock to downrock are called "drops."
