A collage is an art technique where you take things like magazines, newspaper, ribbons,or photos, and glue it to a piece of paper. Collages are known to have been around for hundreds of years. The name was invented in the early 20th century by Georges Braque and Pablo Picasso.
Collages were first created around the time when paper was first invented in China, around 200 BC, but they didn't really get popular until around the 10th century. Collages started being used in Europe in the 13th century. People would put gold leaflets or other pieces of metal on religious pieces of art. This became more popular in the 15th and 16th century.
Some people argue that the collages from this time were not real collages, and that real collages were not invented until the early 1900s. This is probably because of the collages that were made by famous artists like Picasso.
In some of the older collage techniques, people would paint random shapes and other things. According to some articles, Picasso was one of the first artists to make a collage with oil paintings. Before using paint, people would use charcoal instead. Around the 1920s, people started making collages with wood. The most recent version of collages is cutting out pictures from magazines or newspapers and gluing them all together to form another image. This started to get popular around the 1950s.
