Answer 2

The name Palestine (referring to the territory which makes up modern-day Israel) was used by Ancient Greek writers, and was later used for the Roman province Syria Palaestina, the Byzantine Palaestina Prima.

Therefore, in the days of the Greeks, the governing body of the Jews in Palestine was the Jewish monarchy.

Later, when Palestine was a Roman province, the Roman Empire was the governing body.

And even later, the Byzantine empire was the governing body.
