Yugoslavia

Yugoslavia, or Југославија, was a country in the Balkans.

Yugoslavia was formed at the end of World War I as the State of Slovenes, Croats and Serbs, with Serbia joining soon after. Bosnia and Herzegovina, Croatia-Slavonia plus Slovenia released their own stamps before the 1921 constitution that established the Yugoslavian monarchy. Until then, Bosnia and Herzegovina, Croatia-Slavonia and Slovenia issued their own stamps. See: Yugoslavian provisional issues.

Federal republic

 * In November 1945, a republic was declared. Its first stamps were Serbian stamps surcharged with Демократска Федеративна Југославија. These look like semipostals but are regular issues.
 * In late 1946, inscriptions became ФНР ЈУГОСЛАВИЈА, FNR JUGOSLAVIJA or both together.
 * Sometime in 1955, most stamps would mostly be inscribed ЈУГОСЛАВИЈА, or JUGOSLAVIJA.
 * In December 1955, PTT in tiny letters was added to inscriptions.
 * In 1991, parts of the federation declared their independence. In 1992, Montenegro and Serbia joined to form a new federation of Yugoslavia. It continued to issue stamps as Yugoslavia until February of 2003. That country then adopted the name of Serbia and Montenegro.
