The Eight Articles of London, also known as the London Protocol of 21 June 1814, were a secret convention between the Great Powers: the United Kingdom, the Kingdom of Prussia, the Austrian Empire, and the Russian Empire (the four leading nations of the Sixth Coalition against France) to award the territory of current Belgium and The Netherlands to William I of the Netherlands, then "Sovereign Prince" of the United Netherlands. He accepted this award on 21 July 1814.
