just find a curious little thing while searching for other informations in some encyclopedias.
between 1953 and 1954, Italy lost about 500 km² of territory but there is any war treaty for italy during this period? how tat happened?
Someone would need to confirm but given the year it could be linked to the status of Trieste. u/AlviseFalier wrote a detailed comment about Trieste previously. The 1954 partition is mentioned at the end.
