Ancient history...

...During historical times, Trizinia is Dorian along with Methana and Kalavria. Those days, Trizinia was part of Argos and from there it seems that they accepted the Dorians as their inhabitants.

At the Dorian descent or a little later on, the citizens of Trizinia established the cities of Alikarnassos, Mindos and Theagkela on the southwest coast of Asia Minor.

According to the most prevailing version, the founding of the Amphictiony of Kalavria goes back to the Geometric and Archaic eras. Having the temple of Poseidon as the base in Kalavria, the Amphictionic League is set up as a religious and, in the end, political federation. Ermioni, Epidavros, Aegina, Prasies, Orhomenos and Athens were the seven city members.

Its purpose was to resolve any disputes as well as for commercial transactions. It reached its peak from the last prehistoric years up until the 5th century B.C.

Later on, inhabitants of Kalavria along with the cities that form the Amphictiony create Sibari located in southern Italy, offering the name Kalavria throughout its neighboring area taken from the Amphictiony of Kalavria.

That is how the residents of Trizinia and Kalavria turned out to be the founders of Alikarnasos, Mindos and Theagkela in Asia Minor, Sibari and the surrounding area of Kalavria in southern Italy along with the municipalities of Sfittos, Anaflistos and Pithaes in Attica.
