Jew

Identity and legal definitions

Jewish identity is understood in several overlapping ways: ethnic, religious, cultural and national. Traditional Jewish law, known as Halakha, generally defines a Jew as someone born to a Jewish mother or someone who has undergone a formal conversion process according to accepted religious standards. Many Jews, however, identify as such by patrilineal descent, upbringing, ancestry, or self-identification, and different communities apply varied criteria.

Origins and historical development

The Jewish people trace their origins to the ancient peoples of the Levant and to the early Israelite and Judean polities. Over centuries, religious texts (including the Torah), rabbinic writings and communal institutions helped shape a distinct identity. Through periods of sovereignty and exile, Jews maintained communal life, law and learning, developing diverse rites and traditions in different regions.

Distribution and the diaspora

Today Jews live around the world. The modern State of Israel is the only country with a large Jewish majority and functions as a central political and cultural homeland for many Jews. Significant Jewish communities also exist in the United States, where a large population resides, and in countries of Europe, Latin America and elsewhere. Communities in the Europe, Argentina, and Australia illustrate the broad geographic spread. Historically large populations in the former Soviet Union diminished through migration in the late 20th century.

Beliefs, practices and culture

Religious observance varies widely. Some Jews adhere closely to halakhic practice—keeping the Sabbath, observing dietary laws, and participating in synagogue life—while others emphasize cultural, secular or ethical forms of Jewish identity. Jewish life is marked by annual festivals (such as Passover and Yom Kippur), life-cycle rituals (birth, coming-of-age, marriage and mourning), a body of religious literature and communal institutions.

Persecution, memory and modern implications

Jews have faced discrimination and violent persecution at different times and places. The most catastrophic example in modern history is the Holocaust, in which approximately six million Jews were murdered by the Nazi regime and its collaborators. That event and other instances of anti-Jewish violence remain central to Jewish memory and to international discussions about human rights, antisemitism and genocide prevention. Scholarly and public resources document both historical persecutions and contemporary forms of prejudice and intolerance (persecutions).

Distinctive facts and contemporary issues

• Jews may be described as an ethnic group, a religious community, or a nation in cultural terms; different contexts emphasize different aspects.
• The existence of a Jewish majority in Israel is a defining element of modern Jewish politics and identity; global communities remain largely diasporic with major concentrations in the United States and elsewhere.
• Questions of who is a Jew affect religious practice, civil status and immigration policy in various settings; debate continues over conversion standards and communal recognition (majority and minority issues).
