Still looking for when the Jews were legally let back in to Jerusalem

Answer 1

their were always Jews in Israel from the time of King David.

while many Jews were expelled from Judah after 70 ad their were still very large communities that existed long after.

Answer 2

By 70 A.D., Jerusalem and Judea were left desolate, most of the people either killed or being held in captivity, or had become refugees fleeing to remote lands. All that remained in Israel was the defiant little garrison atop the mount at Masada, a fortress complex south of the Dead Sea, which was built by Herod the Great. Thus when the Temple was destroyed in A.D. 70 the period of the second exile began. (Diaspora) The Jewish people were soon to be scattered throughout the earth. For the next 1900 years the Jews would have no authority in the land God gave to Abraham, Isaac, and Jacob.

Answer 3

Israel became an independent nation in 1948, however, they were recognized as a Jewish Homeland in 1917 under the terms of the Balfour Declaration when "Palestine" was set aside by the British Empire as a Jewish settlement.
