For instance, did the "Jesus Movement" start there or elsewhere?
But what about the region itself?
At the time of Jesus, it formed a little inland district of its own, bounded by mountains to the north, west, and south, and the Lake of Genneseret to the east.
Galileans lived among rocky hills and gentle valleys, dotted with small villages and abundantly watered by springs and rains. They were self-sufficient, producing a healthy economy of fish, wine, grains, olives, and fruits, as well as crafts. There were mineral hot springs at Tiberias and Gadara. These and the tropical climate around the "Sea of Galilee" made the area attractive as a health resort.
So with major roadways open to the main north-south highways, one along the seacoast and another across the highlands of the Transjordan to the east, Galilee had constant contact with the rest of the world.
During the Hellenistic period, Galilee was introduced to Greek language, philosophy, art, and culture through the founding of cities on the Greek model in strategic locations up and down the Jordan river valley (Caesarea Philippi, Philoteria, Scythopolis), on the eastern side of the Sea of Galilee (Bethsaida, Hippos, Gadara), along the seacoast to the west (Ptolemais, Dora, Caesarea), and eventually within Galilee itself (Sepphoris, Tiberius, Agrippina). With them came Greek learning, Greek schools with their gymnasia, theaters, forums, and political institutions.
During the time of Jesus, there were twelve Greek cities within a twenty-five-mile radius of his hometown, Nazareth.

There is no record of Galileans fighting under their own banner, trying to rid their land of unwanted foreign kings.
They had no capital city to defend and no king to rule them.
They granted token allegiance to each new foreign king and then looked for ways to protect themselves from any "kings" long arm, neither were they open to, or easily annexed by, either the kingdoms to the north or to the south.
The people who lived in Galilee were Galileans, not Syrians, not Samaritans, not even Jews. It was, as later rabbis' would claim, the “district of the gentiles.”
Interesting place for the young Jesus to grow up in dontcha think?
