Trieste Zone A

 Under construction 

Venezia Giulia

 * After the surrender of German armies in Italy in September 1945, Yugoslavian partisans occupied the region known as Venezia Giulia around Trieste and Fiume. With the arrival of Allied forces, Italian stamps were overprinted A.M.G. / V.G. in 1945, including airmails and special delivery stamps. See: Trieste Zone A.
 * That region was partitioned between the occupiers in June 1945, creating Trieste Zones A and B.

Free Territory of Trieste
A.M.G. - F.T.T. stands for Allied Military Government - Free Territory of Trieste. Beginning in 1947, Italian stamps were overprinted in various styles for use in Zone A of the independent region that was administered by the Allies following World War II. This arrangement continued until November 1954 after which most of Zone A was reunified with Italy with Italian stamps being used thereafter.
