About the everlasting peace between the nations

During the battle at Olszynka Grochowska in defence of Warsaw in 1831, Wojciech Jastrzębowski formulated a document which may be described as a project of the first constitution of Europe united as one republic without internal borders, with unified judicial system and institutions consisting of representatives of all nations. The document named ‘About the everlasting peace between the nations’ („O wiecznym pokoju między narodami”) consisted of 77 articles. It was published on 3 May 1831 on the anniversary of the Polish Constitution of May 3rd. In his text he suggested that all nations should renounce their freedom and become enslaved with the laws, all monarch should be henceforth the guardians and executors of these laws and should not be referred to with no other title than fathers of nations.
