Map of the Persian province of Judah
After the Jewish nation of Judah fell to Babylonian invaders in 586, many survivors lived in exile. Some returned 50 years later, when Persians freed them.
It was only a partial freedom. The Jews lived for the next 200 years as a tiny province of Persia: Yehud, which is translated "Judah" or "Judea."
It was roughly a 40-mile-wide square plug of ground (60 km), in territory that became known as Palestine. The Jewish province included Jerusalem and beyond, into what are now central parts of Israel and Occupied Palestinian Territories.
Jerusalem is where Jews sacrificed animals to God. So when the Jews returned, they built a new temple and later restored some of the walls around the city, but not to the larger size it was before the defeat.
