Which country has the largest number of Jews in the world?

It is Israel. Israel is the only country in the world with Jews as its main ethnic group.

Statistics show that the population of Israel has now exceeded 8 million, of which 6 million are Jews. 1948 after the founding of Israel, Jewish immigrants were strongly encouraged to return to their homeland. At present, there are about13.8 million Jews in the world.

Although the Jewish population is less than 0.25% of the global population, it has won 22% of the global Nobel Prize. The probability of winning the Nobel Prize is much higher than that of other countries, which is 108 times of the global average. Albert Einstein, Freud, Marx, von Neumann and other historical geniuses all came from this small group.

Ethnic origin of Jews

Jews belong to a kind of Semitic people. They wandered in the grasslands of the Euphrates River valley in the 3rd century BC/KLOC-0, and entered Canaan, which was later called Palestine, in the middle of the 2nd century BC/KLOC-0. At that time, Canaanites called foreigners "Hebrews", meaning "people on the other side of the river" ("River" refers to the Euphrates River).

According to the historical records of the Old Testament, their distant ancestor Abraham lived near the Ur Empire of Sumerians and later moved to Canaan (present-day Israel/Palestine). He had two sons, and the youngest son Isaac became the ancestor of the Jews. According to the Bible and the Koran, the descendants of Ishmael, Abraham's eldest son, and Hagar, the maid, are Arabs. So in primitive blood, Jews and Arabs are very close.
