Free climbing is a form of rock climbing in which the climber can only use climbing equipment for climbing protection, but not as an aid to help in their progression in ascending the route. Free climbing, therefore, cannot use any of the tools that are used in aid climbing to help overcome the obstacles encountered while ascending a route. The development of free climbing was an important moment in the history of rock climbing, including the concept and definition of what determined a first free ascent of a route by a climber.

Rock climbing is a sport in which participants climb up, across, or down natural rock formations or indoor climbing walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. Knowledge of proper climbing techniques and the use of specialized climbing equipment is crucial for the safe completion of routes.
