practiced their own oral traditions and customs (caviloth), such as: burying the dead; marrying under a chuppah; observing Shabbat and other Jewish festivals, and maintaining a beit din. However, they adopted some aspects of Christianity after the arrival of British Baptist missionaries during the early 19th century although nominally practicing Judaism. Because of the long period in which the people were not practicing Judaism, they did not develop any distinctly identifiable Judæo-Telugu language as other groups did. Beta Israel of Ethiopia The Beta Israel ("House of Israel") are Ethiopian Jews, who were also called "Falashas" in the past. Some members of the Beta Israel, as well as several Jewish scholars, believe that they are descended from the lost Tribe of Dan, as opposed to the traditional account of their origins which claims that they are descended from the Queen of Sheba and the Israelite king Solomon. They have a tradition of being connected to Jerusalem. Early DNA studies showed that they were descended from Ethiopians, but in the 21st century, new studies have shown their possible descent from a few Jews who lived in either the 4th or 5th century CE, possibly in Sudan. The Beta Israel made contact with other Jewish communities in the later 20th century. In 1973 Rabbi Ovadia Yosef, then the Chief Sephardic Rabbi, based on the Radbaz and other accounts, ruled that the Beta Israel were Jews and should be brought to Israel; two years later that opinion was confirmed by a number of other authorities who made similar rulings, including the Chief Ashkenazi Rabbi Shlomo Goren. Igbo Jews The Igbo Jews of Nigeria variously claim descent from the tribes of Ephraim, Naphtali, Menasseh, Levi, Zebulun and Gad. The theory, however, does not hold up to historical scrutiny. Historians have examined the historical literature on West Africa from the colonial era and they have elucidated that such theories served diverse functions for the writers who proposed them. Black Hebrew Israelites The Black Hebrew Israelites are an African American new religious movement who claim to be the descendants of the Ten Lost Tribes. The group believe that, following their displacement, the Ten Lost Tribes migrated to and settled in West Africa and were subsequently enslaved and transported to America in the Transatlantic slave trade; where they were forced to abandon their Jewish culture and adopt Christianity by their white slavemasters. The Black Hebrew Israelites also believe
