Paper folding originated in Japan in the 6th century and evolved into the art of origami. Initially, paper was expensive and reserved for formal ceremonies, where simple folded designs symbolized sincerity. Paper making spread from Asia to Europe between the 8th and 12th centuries along the Silk Road. In the 1950s, standardized folding symbols were developed to describe origami folds, making the craft more accessible. Origami grew in popularity and complexity, with professional artists designing intricate models.
