The Law of Return
On July 5, 1950, the Law of Return was passed in Israel. This law gives Jewish people the legal right to come and live in Israel and obtain citizenship. "Every Jew has the right to come to Israel as an Oleh!"
Part of what makes Israel unique is the fact that it is indeed the one and only Jewish State. And that is partially due to the Law of Return. Where else can you get citizenship solely based on your religious roots? All Jews can become Israeli citizens because of this law!
In 1970, this law was even further extended to include citizenship rights to non-Jewish children, grandchildren, and spouses, to guarantee that families could stay together.
The Law of Return was a catalyst in gathering Jews from all over the world! It's evident from the fact that over 688,000 Jews came to Israel during the first three years after the law was passed -- the largest Aliyah ever.
Don't forget, this mass Aliyah took place when Israel was first created--and had scarce resources and supplies. Somehow, those early immigrants managed to turn Israel into the land of abundance that we see today!
