Miniature models are derived from toy soldiers which were constructed of a variety of materials, These toy figures came to be mass produced from tin in late 1700s Germany, where they were called Zinnsoldaten (lit. "tin soldiers"). These early figures were flat models commonly called "flats", and became quite common in western Europe. By the mid 1800s manufactures in several countries were producing 3d miniatures of tin and lead alloys, common called white metal. In the 20th century miniatures would also be manufactured from plastic and composite materials.
