EUR-Lex: Treaties According to the website, this page offers "the basic legal texts on which the European Union and the European Communities are founded: the founding Treaties (original versions and later updatings), the amending Treaties, the Accession Treaties for each of the six enlargements, plus other essential documents." The page also provides "consolidated" texts of treaties, a text of a treaty as it reads after the incorporation of amendments made by subsequent treaties. A consolidated treaty is not the official text of the treaty, but rather a research aid.
