The First World War left behind many broken lives and bodies among the survivors. This medal was awarded by the Kingdom of Yugoslavia, successor state of the Kingdom of Serbia that was involved in the First World War, plus various other territories liberated mainly from Austro-Hungary, and it went to war invalids and hospitalised officers. It is in the form of a cross on top of a pair of diagonally-crossed flags. On one side is, in profile, on the left, French Marshal Franchet D'Esperey, and, on the right, King Alexander, who was Prince Regent of Serbia during the First World War. D'Esperey ended up commanding the Allied Army of the Orient which was successful in pushing back the Bulgarians on the Salonika Front and for which the grateful Kingdom of Yugoslavia made him an honorary Field Marshal in 1921. On the other side is the Serbian Cyrillic text, 'КЛУБ ОФИЦИРА ИНВАЛИДА И РАТНИКА БОЛЕСНИХ И ОСАКАЋЕНИХ - ЈУГОСЛАВИЈА ЗАХВАЛНОСТ', which transliterates as 'Klub Oficira Invalida i Ratnika Bolesnih i Osakacenih - Jugoslavija Zahvalnost', and which translates to 'Officers Club for Invalids of War, Sick and Disabled - a Grateful Yugoslavia'. This medal was created over a decade after the end of the First World War. Also shown is a diploma issued in 1938 by the same association to thank a certain V. Gajic for their charitable work on behalf of the association. The decorative design features patterns used in Serbian embroidery on the borders, a Royal Yugoslavian eagle at the top, as well as French and Serbian monuments, and also a pair of French and Kingdom of Yugoslavian flags near the bottom, laying over various weaponry including rifles, cannons, sabres, and holstered pistols. || Kingdom of Yugoslavia Commemorative Cross of the Association of War Invalids

Badge commemorating the Kingdom of the Kingdom of Serbs, Croats and Slovenes. || With the end of the First World War, with so much sacrifice, pain, suffering, devastating loss, and other great costs, the Southern Slav people were united within the newly-formed Kingdom of Serbs, Croats and Slovenes, which was declared on 1 December 1918 in Belgrade. The country would later be renamed as the Kingdom of Yugoslavia in 1929, and would last in that form until the Second World War, when the country became communist, with Western and Soviet political, covert, financial, and military backing. This pin badge was to commemorate this forming of a new country that, some would argue, was supposed to be the ideal outcome of the war for the peoples of the region. The badge reads, in Serbian Cyrillic, 'ЗА КРАЉА И ОТАЏБИНУ' (transliterates to 'Za Kralja i Otadzbinu', translating as 'For King and Fatherland'), and shows the date '1.XII.1918'.

Commemorative Medal for the Liberation of the Northern Regions of Yugoslavia 1918/19, and a cap badge of the Slovenian-led, and majority Slovene, 'Serbs, Croats, and Slovenes' forces used late 1918 to around mid-1919 || The Medal for the Liberation of the Northern Regions of Yugoslavia 1918/19 was established in 1939 and was to be awarded to all of those, both military and civilian, who were involved in the liberation of the Slovenian regions of the northern part of the Kingdom of the Serbs, Croats, and Slovenes, later to become the Kingdom of Yugoslavia in 1929. The purpose of the military actions of late 1918, early 1919, was to establish a demarcation line between what would remain of Austria and the bordering province of Slovenia, and that raised a question over the future of Austria's southern provinces of Carinthia and Styria, which was under consideration in the Paris peace conference. By spring 1919, the Austrians had managed to push back, in part, the majority Slovene forces, and it took the intervention of several regiments of Serbian forces to back up the Slovenes to beat back and turn away the Austrians. The border issue was finally settled by a plebiscite in June 1919 where the first of two Austrian zones voted to stay within Austria, rendering a vote in the second zone redundant. One one side of the medal is a Royal Yugoslavian eagle looking over several, symbolic heraldic shields and, on the other side, in Serbian Latin script, the text 'SPOMENICA NA BORBE ZA OSLOBOĐENJE SEVERNIH KRAJEVA JUGOSLAVIJE 1918-19', and which translates to 'Commemoration of the Struggle to Liberate the Northern Territories of Yugoslavia 1918-19', with laurel and oak branches surrounding this and a torch at the top. The medal show here is predominantly red with white and blue edgings, which was the type awarded for military personnel. Civilian versions had ribbons that were predominantly blue, with red and white edgings. Also shown is a short-lived cap badge that was worn by the self-declared 'Serb, Croats, and Slovenes' forces during this time, which did not include the Serbian Army to begin with, but did include ethnic Serbs living outside of Serbia, as well as Croats and Slovenes, the latter of whom made up the majority of this force. By the first half of 1919, the Serbian Army had joined up with the allied 'Serbs, Croats, and Slovenes' forces, and which would become the armed forces of the Kingdom of the Serbs, Croats, and Slovenes. The cap badge has a round, metal back, woven red cloth insert, and the initials 'S.H.S.', the acronym of 'Srbe, Hrvate, i Slovence', which stood for 'Serbss, Croat, and Slovenes'.
