Techniques of collage were first used at the time of the invention of paper in China, around 200 BC. The use of collage, however, wasn't used by many people until the 10th century in Japan, when calligraphers began to apply glued paper, using texts on surfaces, when writing their poems. The technique of collage appeared in medieval Europe during the 13th century. Gold leaf panels started to be applied in Gothic cathedrals around the 15th and 16th centuries. Gemstones and other precious metals were applied to religious images, icons, and also, to coats of arms. An 18th-century example of collage art can be found in the work of Mary Delany. In the 19th century, collage methods also were used among hobbyists for memorabilia (e.g. applied to photo albums) and books (e.g. Hans Christian Andersen, Carl Spitzweg).
Many institutions have attributed the beginnings of the practice of collage to Picasso and Braque in 1912, however, early Victorian photocollage suggest collage techniques were practiced in the early 1860s. Many institutions recognize these works as memorabilia for hobbyists, though they functioned as a facilitator of Victorian aristocratic collective portraiture, proof of female erudition, and presented a new mode of artistic representation that questioned the way in which photography is truthful. In 2009, curator Elizabeth Siegel organized the exhibition: Playing with Pictures  at the Art Institute Chicago to acknowledge collage works by Alexandra of Denmark and Mary Georgina Filmer among others. The exhibition later traveled to The Metropolitan Museum of Art and The Art Gallery of Ontario.

Despite the pre-twentieth-century use of collage-like application techniques, some art authorities argue that collage, properly speaking, did not emerge until after 1900, in conjunction with the early stages of modernism.
For example, the Tate Gallery's online art glossary states that collage "was first used as an artists' technique in the twentieth century.". According to the Guggenheim Museum's online art glossary, collage is an artistic concept associated with the beginnings of modernism, and entails much more than the idea of gluing something onto something else. The glued-on patches which Braque and Picasso added to their canvases offered a new perspective on painting when the patches "collided with the surface plane of the painting." In this perspective, collage was part of a methodical reexamination of the relation between painting and sculpture, and these new works "gave each medium some of the characteristics of the other," according to the Guggenheim essay. Furthermore, these chopped-up bits of newspaper introduced fragments of externally referenced meaning into the collision: "References to current events, such as the war in the Balkans, and to popular culture enriched the content of their art." This juxtaposition of signifiers, "at once serious and tongue-in-cheek," was fundamental to the inspiration behind collage: "Emphasizing concept and process over end product, collage has brought the incongruous into meaningful congress with the ordinary."
Collage in painting
Collage in the modernist sense began with Cubist painters Georges Braque and Pablo Picasso. According to some sources, Picasso was the first to use the collage technique in oil paintings. According to the Guggenheim Museum's online article about collage, Braque took up the concept of collage itself before Picasso, applying it to charcoal drawings. Picasso adopted collage immediately after (and could be the first to use collage in paintings, as opposed to drawings):
"It was Braque who purchased a roll of simulated oak-grain wallpaper and began cutting out pieces of the paper and attaching them to his charcoal drawings. Picasso immediately began to make his own experiments in the new medium."
In 1912 for his Still Life with Chair Caning (Nature-morte à la chaise cannée), Picasso pasted a patch of oilcloth with a chair-cane design onto the canvas of the piece.
Surrealist artists have made extensive use of collage. Cubomania is a collage made by cutting an image into squares which are then reassembled automatically or at random. Collages produced using a similar, or perhaps identical, method are called etrécissements by Marcel Mariën from a method first explored by Mariën. Surrealist games such as parallel collage use collective techniques of collage making.
The Sidney Janis Gallery held an early Pop Art exhibit called the New Realist Exhibition in November 1962, which included works by the American artists Tom Wesselmann, Jim Dine, Robert Indiana, Roy Lichtenstein, Claes Oldenburg, James Rosenquist, George Segal, and Andy Warhol; and Europeans such as Arman, Baj, Christo, Yves Klein, Festa, Rotella, Jean Tinguely, and Schifano. It followed the Nouveau Réalisme exhibition at the Galerie Rive Droite in Paris, and marked the international debut of the artists who soon gave rise to what came to be called Pop Art in Britain and The United States and Nouveau Réalisme on the European continent. Many of these artists used collage techniques in their work.
Wesselmann took part in the New Realist show with some reservations, exhibiting two 1962 works: Still life #17 and Still life #22.
Another technique is that of canvas collage, which is the application, typically with glue, of separately painted canvas patches to the surface of a painting's main canvas. Well known for use of this technique is British artist John Walker in his paintings of the late 1970s, but canvas collage was already an integral part of the mixed media works of such American artists as Conrad Marca-Relli and Jane Frank by the early 1960s. The intensely self-critical Lee Krasner also frequently destroyed her own paintings by cutting them into pieces, only to create new works of art by reassembling the pieces into collages.
Collage with wood

The wood collage is a type that emerged somewhat later than paper collage. Kurt Schwitters began experimenting with wood collages in the 1920s after already having given up painting for paper collages. The principle of wood collage is clearly established at least as early as his 'Merz Picture with Candle', dating from the mid to late 1920s.
In a sense, wood collage made its debut indirectly at the same time as paper collage, since according to the Guggenheim online, Georges Braque initiated use of paper collage by cutting out pieces of simulated oak-grain wallpaper and attaching them to his own charcoal drawings. Thus, the idea of gluing wood to a picture was implicit from the start, since the paper used was a commercial product manufactured to look like wood.
It was during a fifteen-year period of intense experimentation beginning in the mid-1940s that Louise Nevelson evolved her sculptural wood collages, assembled from found scraps, including parts of furniture, pieces of wooden crates or barrels, and architectural remnants like stair railings or moldings. Generally rectangular, very large, and painted black, they resemble gigantic paintings. Concerning Nevelson's Sky Cathedral (1958), the Museum of Modern Art catalogue states, "As a rectangular plane to be viewed from the front, Sky Cathedral has the pictorial quality of a painting..." Yet such pieces also present themselves as massive walls or monoliths, which can sometimes be viewed from either side, or even looked through.
Much wood collage art is considerably smaller in scale, framed and hung as a painting would be. It usually features pieces of wood, wood shavings, or scraps, assembled on a canvas (if there is painting involved), or on a wooden board. Such framed, picture-like, wood-relief collages offer the artist an opportunity to explore the qualities of depth, natural color, and textural variety inherent in the material, while drawing on and taking advantage of the language, conventions, and historical resonances that arise from the tradition of creating pictures to hang on walls. The technique of wood collage is also sometimes combined with painting and other media in a single work of art.
Frequently, what is called "wood collage art" uses only natural wood - such as driftwood, or parts of found and unaltered logs, branches, sticks, or bark. This raises the question of whether such artwork is collage (in the original sense) at all (see Collage and modernism). This is because the early, paper collages were generally made from bits of text or pictures - things originally made by people, and functioning or signifying in some cultural context. The collage brings these still-recognizable "signifiers" (or fragments of signifiers) together, in a kind of semiotic collision. A truncated wooden chair or staircase newel used in a Nevelson work can also be considered a potential element of collage in the same sense: it had some original, culturally determined context. Unaltered, natural wood, such as one might find on a forest floor, arguably has no such context; therefore, the characteristic contextual disruptions associated with the collage idea, as it originated with Braque and Picasso, cannot really take place. (Driftwood is of course sometimes ambiguous: while a piece of driftwood may once have been a piece of worked wood - for example, part of a ship - it may be so weathered by salt and sea that its past functional identity is nearly or completely obscured.)
Decoupage is a type of collage usually defined as a craft. It is the process of placing a picture into an object for decoration. Decoupage can involve adding multiple copies of the same image, cut and layered to add apparent depth. The picture is often coated with varnish or some other sealant for protection.
In the early part of the 20th century, decoupage, like many other art methods, began experimenting with a less realistic and more abstract style. 20th-century artists who produced decoupage works include Pablo Picasso and Henri Matisse. The most famous decoupage work is Matisse's Blue Nude II.
There are many varieties on the traditional technique involving purpose made 'glue' requiring fewer layers (often 5 or 20, depending on the amount of paper involved). Cutouts are also applied under glass or raised to give a three-dimensional appearance according to the desire of the decouper. Currently decoupage is a popular handicraft.
The craft became known as découpage in France (from the verb découper, 'to cut out') as it attained great popularity during the 17th and 18th centuries. Many advanced techniques were developed during this time, and items could take up to a year to complete due to the many coats and sandings applied. Some famous or aristocratic practitioners included Marie Antoinette, Madame de Pompadour, and Beau Brummell. In fact the majority of decoupage enthusiasts attribute the beginning of decoupage to 17th century Venice. However it was known before this time in Asia.
The most likely origin of decoupage is thought to be East Siberian funerary art. Nomadic tribes would use cut out felts to decorate the tombs of their deceased. From Siberia, the practice came to China, and by the 12th century, cut out paper was being used to decorate lanterns, windows, boxes and other objects. In the 17th century, Italy, especially in Venice, was at the forefront of trade with the Far East and it is generally thought that it is through these trade links that the cut out paper decorations made their way into Europe.
Collage made from photographs, or parts of photographs, is called photomontage. Photomontage is the process (and result) of making a composite photograph by cutting and joining a number of other photographs. The composite picture was sometimes photographed so that the final image is converted back into a seamless photographic print. The same method is accomplished today using image-editing software. The technique is referred to by professionals as compositing.
Just what is it that makes today's homes so different, so appealing? was created in 1956 for the catalogue of the This Is Tomorrow exhibition in London, England in which it was reproduced in black and white. In addition, the piece was used in posters for the exhibit. Richard Hamilton has subsequently created several works in which he reworked the subject and composition of the pop art collage, including a 1992 version featuring a female bodybuilder. Many artists have created derivative works of Hamilton's collage. P. C. Helm made a year 2000 interpretation.
Other methods for combining pictures are also called photomontage, such as Victorian "combination printing", the printing from more than one negative on a single piece of printing paper (e.g. O. G. Rejlander, 1857), front-projection and computer montage techniques. Much as a collage is composed of multiple facets, artists also combine montage techniques. Romare Bearden’s (1912–1988) series of black and white "photomontage projections" is an example. His method began with compositions of paper, paint, and photographs put on boards 8½ × 11 inches. Bearden fixed the imagery with an emulsion that he then applied with handroller. Subsequently, he enlarged the collages photographically.
The 19th century tradition of physically joining multiple images into a composite and photographing the results prevailed in press photography and offset lithography until the widespread use of digital image editing. Contemporary photo editors in magazines now create "paste-ups" digitally.
Creating a photomontage has, for the most part, become easier with the advent of computer software such as Adobe Photoshop, Pixel image editor, and GIMP. These programs make the changes digitally, allowing for faster workflow and more precise results. They also mitigate mistakes by allowing the artist to "undo" errors. Yet some artists are pushing the boundaries of digital image editing to create extremely time-intensive compositions that rival the demands of the traditional arts. The current trend is to create pictures that combine painting, theatre, illustration and graphics in a seamless photographic whole.
Digital collage is the technique of using computer tools in collage creation to encourage chance associations of disparate visual elements and the subsequent transformation of the visual results through the use of electronic media. It is commonly used in the creation of digital art.
A 3D collage is the art of putting altogether three-dimensional objects such as rocks, beads, buttons, coins, or even soil to form a new whole or a new object. Examples can include houses, bead circles, etc.
It is the art of putting together or assembling of small pieces of paper, tiles, marble, stones, etc. They are often found in cathedrals, churches, temples as a spiritual significance of interior design.Small pieces, normally roughly quadratic, of stone or glass of different colors, known as tesserae, (diminutive tessellae), are used to create a pattern or picture.
The term "eCollage" (electronic Collage) can be used for a collage created by using computer tools.
