How did Judaism affect the culture of the Jews in the Diaspora?

Answer 1

The Jews were scattered during the Diaspora and that helped them spread out around Asia, Africa, Europe, and all those places to make villages dotted all around and to people who passed through their villages be taught about Christianity and went to other villages that were not Jewish, then talk about to random people everywhere about what they heard in the Jewish villages. I presume that some of them were killed because they believed in the Jewish God, and others were not because they kept to themselves and sometimes did not believe in the Jewish God. So, eventually people started believing in Christianity all over the world.

Answer 2

Let's see a few examples.Language:

In many cases, Jewish communities created their own languages that were based on the local language but quite different from it. These include Yiddish, Ladino, Judeo-Arabic, and others.

Speech:

Jewish speech (in any language), especially among religious communities, is seasoned with hundreds of expressions that refer to various Torah-concepts.

Instead of saying "Tomorrow I'll visit," the phrase will be "Tomorrow I'll visit im yirtzeh Hashem" (God willing). See also: An extensive Jewish glossary of words

Cuisine:

Jews have created certain foods in keeping with Torah-requirements. Matzoh-ball soup and matzoh-breionPassover replace any leavened equivalent. Gefilte fish (which contains no bones) was created to avoid the stricture against separating bones from food on the Shabbat.

Home design:

Here in Israel, homes in religious neighborhoods tend to be designed with two sinks in the kitchen, an additional sink for handwashing outside the bathroom, and a porch for the sukkah.

Charity:

At every Jewish religious wedding, and in very many synagogues, you'll encounter people collecting alms for the indigent. Every religious home has at least one pushke (charity-box) which, when filled, is donated to the tzedakah (charity) of one's choice.

I've tried to give examples that are not in themselves obligatory, but reflect Torah-commands or attitudes.

Answer 3

It caused the spread of Judaism.

1) Around 2600 years ago, the Assyrians forcibly exiled the Ten Israelite tribes to points unknown. A small percentage of each of these tribes is still among us, but most of them were exiled and didn't return.
2) Around 2500 years ago, the Babylonians destroyed the First Temple and forcibly exiled the remainder of Israel's population to Babylonia. (See: The Destruction)
While the Jews were permitted to return to Israel (Judea) seventy years later, and tens of thousands did so (and rebuilt the Temple), most of them remained in Babylonia, while others began to settle in North Africa, southern Europe, the Crimea, throughout the Near East and elsewhere.

3) In 68 CE, the Romans destroyed the Second Temple. The Romans did not force the Jews out of Judea in a single expulsion. Rather, the Romans expelled them from Jerusalem only; and the rest of Judea lost its Jews slowly, over a period of centuries, as living there became too harsh. Even then, we have records of Jewish communities who lived in Judea (Palestine) during the entire period of the last two millenia. (See:History of the Jews in Israel)

Those Jews who left Judea went to southern Europe, North Africa, Arabia, the Near East, and (slowly) further afield (especially throughout Europe).

Where do Jews live today?

Related topic:
The diaspora (scattering) was difficult for us:

1) Because certain mitzvot (such as those related to agriculture in the Holy Land) now became suspended for the duration of the exile.

2) Because of the impediment to communication between the various communities. This could lead to the development of rivaling groups, each claiming to be authentic.

(See for example: What are the Karaites?)

3) Because the Jews were now a minority among other nations, who were sometimes quite hostile.

4) Along with the Torah, the Land of Israel (Judea) and the Holy Temple had been central to Judaism. It now was to be seen whether Torah-observance could be maintained on the high level that those ideal factors had been conducive to.

How did the diaspora affect the Jews?
To a certain extent, the diaspora caused the various Jewish communities to take on minor aspects of their host countries.
The religion itself was affected little, if at all, since all Jews share the same Torah and Talmud, and differences within halakhah (Jewish laws) are relatively small. In addition, the Jews were dissuaded from assimilating because the Romans were the polar opposite of Judaism; plus the fact that some of their greatest historians spewed diatribes of hate against the Jews.However, in secondary matters of culture such as pronunciation, mannerisms, and introduction of new vocabulary, every community is influenced somewhat by the others among whom they dwell; so some traits of our regions of residence have rubbed off on us. Examples are the differences in pronunciation and accent (for the Hebrew alphabet), differences in dress, and minor differences in customs.
