The Treaty of Saint Germain was signed with Austria on September 10, 1919 and was to a large extent modelled on the Treaty of Versailles. The treaty recognized the independence of Hungary, Poland and Yugoslavia. She ceded South Tyrol, the Trentino, Trieste, Istria and Dalmatian Islands to Italy; Bukovina to Rumania, Bosina, Herzegovina and the Dalmatian coast to Yugoslavia, Morvia, part of lower Austria and Austrian Silesia to Czechoslovakia, Austrian Galecio to Poland; and Teschen to Poland and Czechoslovakia. Thus three-fourth of the territory and people were detached from Austria.
The Treaty forbade the union between Austria and Germany and greatly curtailed the military and navy of Austria. Her army was reduced to 30,000 volunteers and her navy was reduced to three police boats on the Danube.
She was accorded access to the Adriatic Sea across the territories that formerly formed part of the Hapsburg domain. Austria assented to blank reparation cheque and acknowledged the right of the Allies to try Austrian ‘war criminals’.
However, all claims of reparation from Austria were repudiated in 1921 and the Reparation Commission appointed to realize compensation for war damages was turned into a relief organization. The Articles of the Treaty of Versailles concerning the Covenant of the League of Nations and the I.L.O. were also adopted in the treaty.
