History of Rock Climbing

Although rock climbing was an important component of Victorian mountaineering in the Alps, it is generally thought that the sport of rock climbing began in the last quarter of the nineteenth century in various parts of Europe. Rock climbing evolved gradually from an alpine necessity to a distinct athletic activity.
Aid climbing (climbing using equipment that acts as artificial hand- or footholds) became popular during the period 1920 - 1960, leading to ascents in the Alps and in Yosemite Valley that were considered impossible without such means. However, climbing techniques, equipment, and ethical considerations have evolved steadily, and today, free climbing (climbing on holds made entirely of natural rock, using gear solely for protection and not for upward movement) is the most popular form of the sport. Free climbing has since been divided into several sub-styles of climbing dependent on belay configuration (described below).
Over time, grading systems have also been created in order to more accurately compare the relative difficulties of climbs.
