This study is dedicated to approaching of the Great Union (occurring in 1918) as a spiritual phenomenon, crucial for the history of the Romanian people. This phenomenon becomes fully understandable only if we place it in an adequate analytical framework consisting from a space-time continuum crossed by a geo-historical axis linking two crucial moments in the history of the New Europe: the Peace of Westphalia (1648) and the Peace in Versailles (1918-20). Among the peace treaties agreed at Versailles, the one signed at Trianon was decisive for the new geopolitical order of Central Europe. In this article we highlight that the Treaty of Trianon is the most representative diplomatic document of a fully European conception in which the foundations of a new model of peace based on the order of the sovereign nations and not of the empires were laid. The study shows all the relevant arguments that lead to the conclusion that the Treaty of Trianon, together with the other Peace Treaties of Versailles, represents the mirror and the only securing geopolitical framework of a completely renovated Europe.

Keywords: peace treaty, New Europe, Westphalian paradigm, the principle of nationality, geopolitical landscape.
