Fur has been used for clothing for thousands of years, probably dating back to the Neanderthals, though its use as clothing diminished with the advent of woven fabrics. Because of its expense, fur has been considered a luxury good and a desirable status symbol for hundreds of years. However, in many arctic cultures, families will often pass down a fur coats for generations, due to the near necessity of such items to keep warm.
 Anti-fur campaigns
Campaigns against the fur industry have been carried out for decades by animal welfare and animal rights organizations such as PETA, the Humane Society of the United States, and the International Fund for Animal Welfare.
Anti-fur activists argue that the killing of animals for fur is unnecessary and unjustifiable slaughter; is dangerous to wildlife population and distribution levels; and a is grave abuse of animal rights. Their campaigns have had some success in restricting the fur trade and reducing the appeal of fur products in some countries, although fur still remains popular elsewhere.
