In his speech to Congress on 8 January 1918, Thomas Woodrow Wilson, the American president, outlined his 14 points which were the principles for peace after World War I. Point XIII of his speech forecast the independence of Poland, which materialized in November, 1918.

President Wilson in his Point XIII emphasized:

An independent Polish state should be erected which should include the territories inhabited by indisputably Polish populations, which should be assured a free and secure access to the sea, and whose political and economic independence and territorial integrity should be guaranteed by international covenant.
