Prior to 1954 when it was transferred to Italy, the area around the city and province
of Trieste alternated between control by Italy and Yugoslavia and an international
administration after WWII. In 1954, Italy was given civil administration of the city
of Trieste and annexed it to Italy. Yugoslavia was given provisional civil administration
of the southern part of the territory of Trieste. This arrangement was made definitive
effective October 11, 1977. Many individuals living in Trieste were born in areas
which are now part of Croatia and Slovenia. Evidence from Trieste for these individuals
can be based on any of a variety of sources and documents.
Church records are the only preferred evidence of age available for persons born prior
to January 1, 1924 in the city and province of Trieste and in those areas which are
now part of Italy.
