It`s Illyrian:

treg
Etymology
Unclear. Possibly from a Balkan substrate, continuing Illyrian *Tergitio (“merchant”). Usually assumed to be connected with Proto-Slavic *tъrgъ, Lithuanian tur̃gus, Latvian tirgus, Swedish torg (“market, marketplace”). This group is considered to be cognate with the Italian city name of Trieste, Latin Tergeste.

Good read. Yes, Slovenes started to demand some Croatian territories in Istria because they got depraved of Slovenian(Slavic) populated lands in Italy, but Italy is too strong so they don't dare to bother them. This is origin of Slovenian-Croatian border dispute.
