An artificial Christmas trees is an artificial pine and fir tree manufactured for the specific purpose of use as a Christmas tree. The earliest artificial Christmas trees were wooden, tree-shaped pyramids or feather trees, both developed by Germans. Most modern trees are made of polyvinyl chloride (PVC) but many other types of trees have been and are available, including aluminum Christmas trees and fiber-optic illuminated Christmas trees.
The first artificial Christmas trees were developed in Germany during the 19th century, though earlier examples exist. These "trees" were made using goose feathers that were dyed green. The German feather trees were one response by Germans to continued deforestation in Germany. Developed in the 1880s, the feather trees became increasingly popular during the early part of the 20th century. The German feather trees eventually made their way to the United States where they became rather popular as well. In fact, the use of natural Christmas trees in the United States was pre-dated by a type of artificial tree. These first trees were wooden, tree-shaped pyramids lit by candles, they were developed in Bethlehem, Pennsylvania, by the German Moravian Church in 1747.
