What other groups had a claim to Israel

Israel was claimed by the native Palestinians who had lived there apart from the Jews.

Explanation:

The land of Israel was a very contested part of the world as it was historically accurate as the place where the Jews lived but this also meant that it was the place where there were less Jews now as they had migrated out.

Now the people who occupied the land were the Palestinian Muslims who themselves had been in the region for hundreds of years and were also natives with a legitimate claim to the land

Eventually it was handed over to Israel to much the dismay of the Muslims of the area.
