Answer:
The answer is
→ Palestine
Step-by-step explanation:
If your actually talking about the county in Asia, then the original name of Israel before it was changed was originally Palestine.
The explanation that Palestine was changed to Israel was on the grounds that in the common conflict among Arabs and Jews, the Arabs dismissed the Partition Plan, the Jews apparently acknowledged it, proclaiming the freedom of the State of Israel in May 1948 upon the end of the British command.
After all this happened, the President of Palestine decided to change the name to Israel to avoid conflict.
Hope this helped! :)
