Berne Convention for the Protection of Literary and Artistic Works is an international agreement which deals with the protection of works and the rights of their authors and mandates equal treatment of copyrighted works by Berne signatories, known as the Berne Union. It is based on the principles of national treatment (i.e. all work to be given the same protection as given to the nation of concerned state), automatic protection (i.e. protection not conditional on any formality / registration) and independence of protection (i.e. Protection is independent of the existence of protection in the country of origin of the work). The Berne Convention was adopted in 1886 in Berne, Switzerland.
