Jewish identity is the objective or subjective state of perceiving oneself as a Jew and as relating to being Jewish. Under a broader definition, Jewish identity does not depend on whether a person is regarded as a Jew by others, or by an external set of religious, or legal, or sociological norms. Jewish identity does not need to imply religious orthodoxy. Accordingly, Jewish identity can be cultural in nature. Jewish identity can involve ties to the Jewish community. Orthodox Judaism bases Jewishness on matrilineal descent. According to Jewish law (halacha), all those born of a Jewish mother are considered Jewish, regardless of personal beliefs or level of observance of Jewish law. Progressive Judaism and Haymanot Judaism in general base Jewishness on having at least one Jewish parent, while Karaite Judaism bases Jewishness only on paternal lineage. These differences between the major Jewish movements are the source of the disagreement and debate about who is a Jew.
