African Jewish communities include:
In the seventh century, many Spanish Jews fled persecution under the Visigoths to North Africa, where they made their homes in the Byzantine-dominated cities along the Mediterranean coast. Others arrived after the expulsion from Iberia. Remnants of longstanding Jewish communities remain in Morocco, Tunisia, and the Spanish cities of Ceuta and Melilla. There is a much-diminished but still vibrant community on the island of Djerba in Tunisia. Since 1948 and the war to establish Israel, which aroused hostility in Muslim lands, most other North African Jews emigrated to Israel.
Of the seventh-century immigrants, some moved inland and proselytized among the Berber tribes. A number of tribes, including the Jarawa, Uled Jari, and some tribes of the Daggatun people, converted to Judaism. Ibn Khaldun reported that Kahina, a female Berber warlord who led the resistance against the Muslim Arab conquests of North Africa in the 680s and 690s, was a Jew of the Jarawa tribe. With the defeat of the Berber rebellion, none of the Jewish communities was initially forced to convert to Islam.
In 1975, the Israeli religious authorities and government recognized the Beta Israel of Ethiopia as legally Jewish. Hundreds of persons who wanted to emigrate to Israel were air-lifted under the leadership of Prime Minister Menachem Begin. Begin had obtained an official ruling from the Israeli Sephardi Chief Rabbi (or Rishon LeTzion) Ovadia Yosef that the Beta Israel were descendants of the Ten Lost Tribes. Rabbis believed they were probably descendants of the Tribe of Dan; rabbinical responsa discussing issues related to the people date back hundreds of years. With this endorsement, in later decades tens of thousands of Beta Israel Jews were air-lifted to Israel. Significant immigration to Israel continues into the 21st century, producing an Ethiopian Jewish community of around 81,000 immigrants, who with their 39,000 children born in Israel itself, numbered around 120,000 by early 2009.
Due to certain aspects of Orthodox Jewish marital laws, Rabbi Yosef ruled that upon arrival in Israel, the Beta Israel had to undergo a pro forma conversion to Judaism. They had to declare their allegiance to a halachic way of life and the Jewish people, in conformity with practices followed by Orthodox Rabbinical Judaism. He did not demand the normal formal requirements that the halacha imposes on potential gentile proselytes, (such as a brit milah or immersion in a mikveh). Few Ashkenazi rabbinic authorities consider the conversions to be actual conversions, not pro forma.
Over time, due to their community's isolation from those in Europe and the Middle East, the practices of the Beta Israel developed to differ significantly from those of other forms of Judaism. In Ethiopia, the Beta Israel community was for the most part isolated from the Talmud. They did have their own oral law. In some cases, they had practices similar to those of Karaite Judaism, and in others more similar to rabbinical Judaism.
In many instances their religious elders, or priestly class, known as kessim or qessotch, interpreted the Biblical Law of the Tanakh in a way similar to the rabbinite Jewish communities in other parts of the world. In that sense, the Beta Israel had a tradition analogous to that of the Talmud, although at times at variance with the practices and teachings of other Jewish communities.
One significant difference is that the Beta Israel lacked the festivals of Purim and Hanukkah, probably because they branched off from the main body of Judaism before these non-Biblical holidays began to be commemorated. Today, most members of the Beta Israel community living in Israel do observe these holidays.
They are a community in transition. Some of the kessim accept the rabbinic/Talmudic tradition that is practiced by non-Ethiopian Orthodox Jews. Many of the younger generation of Ethiopian-Israelis have been educated in yeshivas and received rabbinical ordination (semikha). A certain segment of traditionalist kessim insist on maintaining their separate and distinct form of Judaism, as it had been practiced in Ethiopia and Eritrea. Many of the Ethiopian Jewish youth who have immigrated to Israel or been born there have assimilated either to the dominant form of Orthodox Judaism, or to a secular lifestyle.
The Beit Avraham of Ethiopia have some 50,000 members. This community also claims Jewish heritage. Several scholars think that they broke off from the Beta Israel community several centuries ago, hid their Jewish customs, and outwardly adopted Ethiopian Orthodox Christianity.
Beit Avraham have traditionally been on the lower rungs of Ethiopian social life. They have held occupations similar to those of the Beta Israel, such as crafts. Recently, the Beit Avraham community has attempted to reach out to the world Jewish community. They formed the Ethiopian North Shewa Zionist Organization in an attempt to save their Jewish identity. This group identifies as the Falashmura. As they do not have reliable proof of Jewish ancestry, Israeli religious authorities and other religious Jewish communities require them to complete a formal conversion to be recognized as Jews. Those who do so are considered converts.
The Yibir are a tribe that lives in Somalia, eastern Ethiopia, Djibouti, and northern Kenya. Though they have been Muslim for centuries, some of them assert they are descendants of Hebrews who arrived in the Horn of Africa long before the arrival of Somali nomads. These individuals assert that Yibir means "Hebrew" in their language.
The historical presence of Jewish communities in Africa is well-attested. Today, the descendants of these Jews live in nations such as Sierra Leone, Liberia, Senegal, Ghana, Nigeria, and many other areas. According to the 17th century Tarikh al-Fattash and the Tarikh al-Sudan, several Jewish communities existed as parts of the Ghana, Mali, and later Songhai empires. One such community was formed by a group of Egyptian Jews, who allegedly traveled by way of the Sahel corridor through Chad into Mali. Manuscript C of the Tarikh al-Fattash described a community called the Bani Israel; in 1402, it lived in Tindirma, possessed 333 wells, and had seven princes as well as an army.
Another such community was that of the Zuwa ruler of Koukiya (located at the Niger River). His name was known only as Zuwa Alyaman, meaning "He comes from Yemen". According to an isolated local legend, Zuwa Alyaman was a member of one of the Jewish communities transported from Yemen by Abyssinians in the 6th century CE after the defeat of Dhu Nuwas. Zuwa Alyaman was said to have traveled into West Africa along with his brother. They established a community in Kukiya at the banks of the Niger River downstream from Gao. According to the Tarikh al-Sudan, after Zuwa Alyaman, there were 14 Zuwa rulers of Gao before the rise of Islam in the second half of the eleventh century.
Other sources stated that other Jewish communities in the region developed from people who migrated from Morocco and Egypt; others later came from Portugal. Some communities were said to have been populated by certain Berber Jews, like a group of Tuareg known as Dawsahak or Iddao Ishaak ("children of Isaac"). They speak a language related to Songhai, live in Ménaka Region in northeastern Mali and were formerly herders for Tuareg nobles. In addition, some migrated into the area away from the Muslim rule of North Africa.
The well-known 16th Century geographer Leo Africanus - an Andalusian Berber convert to Christianity - mentions a mysterious small village of African Jews southwest of Timbuktu, who traded in exotic spices, weapons, and poisons.
The largest influx of Jews to Africa came after the Spanish Inquisition after the Fall of Granada and the end of Islamic Spain. The mass exodus and expulsion of the Iberian Jews began in 1492, Sicilian Jews were affected soon afterwards. Many of these Sephardi Jews settled primarily in the Maghreb under Muslim and Ottoman patronage. Morocco, Tunisia, Libya and Algeria as well as Egypt became home to significant Jewish communities. These communities were later incorporated into the Ottoman millet system as Africanized Ottoman Jews, bound by the laws of the Talmud and Torah but with allegiance to the Caliph of Constantinople.
The Nyambo are a tribe that lives in Tanzania, northern Tanzania, and Southern Uganda as Ankole. Though they have been Christians for centuries, they assert they are descendants of Hebrews who arrived in the Horn of Africa long before the arrival of Somali nomads. Some say that Nyambo means "Hebrew" in their language.
In the 14th century many Moors and Jews, fleeing persecution in Spain, migrated south to the Timbuktu area, at that time part of the Songhai Empire. Among them was the Kehath (Ka'ti) family, descended from Ismael Jan Kot Al-yahudi of Scheida, Morocco. Sons of this prominent family founded three villages that still exist near Timbuktu--Kirshamba, Haybomo, and Kongougara. In 1492, Askia Muhammed came to power in the previously tolerant region of Timbuktu and decreed that Jews must convert to Islam or leave; Judaism became illegal in Songhai, as it did in Catholic Spain that same year. As the historian Leo Africanus wrote in 1526: "The king (Askia) is a declared enemy of the Jews. He will not allow any to live in the city. If he hears it said that a Berber merchant frequents them or does business with them, he confiscates his goods."
The Kehath family converted with the rest of the non-Muslim population. The Cohens, descended from the Moroccan Islamicized Jewish trader El-Hadj Abd-al-Salam al Kuhin, arrived in the Timbuktu area in the 18th century, and the Abana family came in the first half of the 19th century. According to Prof. Michel Abitbol, at the Center for the Research of Moroccan Jewry in Israel, in the late 19th century Rabbi Mordoche Aby Serour traveled to Timbuktu several times as a not-too-successful trader in ostrich feathers and ivory. Ismael Diadie Haidara, a historian from Timbuktu, has found old Hebrew texts among the city's historical records. He has also researched his own past and discovered that he is descended from the Moroccan Jewish traders of the Abana family. As he interviewed elders in the villages of his relatives, he has discovered that knowledge of the family's Jewish identity has been preserved, in secret, out of fear of persecution.
King Manuel I of Portugal exiled about 2,000 Jewish children under the age of ten, to São Tomé and Príncipe around 1500. Most died, but in the early 17th century "the local bishop noted with disgust that there were still Jewish observances on the island and returned to Portugal because of his frustration with them."[unreliable source?] Although Jewish practices faded over subsequent centuries, there are people in São Tomé and Príncipe who are aware of partial descent from this population. Similarly, a number of Portuguese ethnic Jews were exiled to Sao Tome after forced conversions to Roman Catholicism. From São Tomé and by other means groups of Jews settled down the west coast of Africa, as far south as Loango.
In 2002 Parfitt wrote "the myth of the Lost Tribes has penetrated every corner of the African continent. The use and re-use of this myth and myths about Jews serving an immense array of ideological and spiritual needs has had a striking impact on Africa. The spread of the myth connecting Africa with the Jews has been spectacular. It arose in the European and Middle Eastern imagination in the early Middle Ages and may be attributed in part to the ignorance of much of the world brought about by the breakdown of communications between the Islamic Middle East and Christian Europe. It became an axiomatic feature of Medieval thinking about the world. It was used and re-used, exploited and re-invented by colonialism in many distinct loci in Africa where it served missionary and colonial interests and is now a largely ignored but potent and immanent aspect of the imagined past of a surprising number of Africans."
In early modern times it was widely believed that Israelites had settled in Madagascar. Works by the French scholar Alfred Grandidier and Augustus Keane, the British professor of Hindustani at University College, London provided what they saw as conclusive proof of these ancient connections. These ideas were absorbed into the national consciousness of the people of Madagascar. In 2010 a small community of Malagasies began practicing normative Judaism, and three separate communities formed, each embracing a different version of Jewish spiritual practice. In May 2016, 121 members of the Malagasy Jewish community were converted in accordance with traditional Jewish rituals; appearing before a beit din and submerged in a mikvah. The conversion, organized with the help of the Jewish organization Kulanu, was presided over by three Orthodox rabbis.
Communities have been forming in Ivory Coast in recent years and have been slowly growing throughout the region. The capitol city of Abidjan has two synagogues, each with a population of about 40-70 congregants. In addition, large groups of indigenous peoples referred to as Danites claim descent from the lost tribe of Dan and many from this ethnic group have shown interest in Judaic practices.
Rabbi Yisrael Oriel, formerly Bodol Ngimbus-Ngimbus, was born into the Ba-Saa tribe. He says there were historically Jews in the area and that the word "Ba-Saa" is from the Hebrew for 'on a journey' and means "blessing". Rabbi Oriel claims to be a Levite descended from Moses and reportedly made aliya in 1988, and he was then apparently ordained as a rabbi by the Sephardic Chief Rabbi and appointed rabbi to Nigerian Jews.
Rabbi Oriel claims that in 1920 there were 400,000 'Israelites' in Cameroon, but by 1962 the number had decreased to 167,000 due to conversions to Christianity and Islam. He said that although these tribes had not been accepted halachically, he believes that he can prove their Jewish status from medieval rabbinic sources.
The father of Yaphet Kotto, an American actor, was a Cameroonian Jew. Kotto identified as Jewish.
From the eighteenth century on what is now Ghana was a favorite locus for theories positing Israelite origins for various ethnic groups in the area. These theories were widespread and were taken up by powerful people in the twentieth century.  The House of Israel community of Sefwi Wiawso, Sefwi Sui has identified as Jewish since the early 1970s.  The Ga-Dangme tribe in the southern Region of Ghana assert that their ancestors are descendants of the tribe Gad and Dan who migrated south through Egypt. They observe many Hebraic traditions such as circumcision of their male child; they also cannot name their male child until he has been circumcised. They also have many ancient Jewish names that are traditional names.
Theories suggesting Israelite origins particularly of the Masai abounded in the nineteenth century and were gradually absorbed into religious and societal practices throughout the area. The chief proponent of Masai Israelite origins was a German officer Moritz Merkel whose detailed research is still in use today. Of the many Judaic manifestations in the religious sphere is a small emergent community in Laikipia County, Kenya, which has abandoned Christianity and taken up Judaism. There are an estimated 5,000 of them at the present time. Although at first Messianic, they concluded that their beliefs were incompatible with Christianity and are now waiting to be instructed in traditional Judaism. Some of the younger children of this community have been sent to the Abayudaya schools in Uganda to be instructed in Judaism and other subjects. Luos in Kenya are another of the groups considered by some to be of Israelite origin. They claim to have migrated hundreds of years ago from the north along the river Nile from Egypt through South Sudan and then into Kenya. 
There have been claims that the Igbo, Esan and Yoruba tribes of what is today Nigeria are of Jewish origin since the eighteenth century. At the present times Israelite associations are mainly attributed to the Igbo many of whom claim Israelite origins. Most of the Jews of Nigeria are to be found among the Igbo ethnic group. Certain Nigerian communities with Judaic practices have been receiving help from individual Israelis and American Jews who work in Nigeria with outreach organizations like Kulanu. The number of Igbos in Nigeria who identify as Jews has been estimated at around 4,000 (2016), with 70 synagogues. Many have converted from Christianity. Other sources put a higher figure, claiming some 30,000 Igbos were practicing some form of Judaism in 2008.
For centuries it was believed that Jews inhabited the central portions of Africa. Some Africans in recent times were keen to adopt Judaism. One of these was Samei Kakungulu, one of the most remarkable Ugandans of his generation, a brilliant military strategist and a man of great spiritual and intellectual curiosity. In 1919, having declared "we now will be known as Jews," he was circumcised along with his first son, whom he called Yuda. His second son was subsequently circumcised on the eighth day, in the Jewish fashion, and was named Nimrod. In 1922 Kakungulu published a 90-page book, which was essentially a guide to Judaism. He died a Jew (albeit one with some residual belief in Jesus) and his followers in Mbale, known as the Bayudaya, despite persecution at the time of Idi Amin when many of the community converted to Christianity or Islam, are today some thousand strong. In the twenty first century the Abayudaya are considered observant followers of Judaism, many having taken a formal orthodox conversion, with strong links with Jewish communities in the United States and Israel, and increasingly strong links with Black Jewish communities in Africa and elsew here. In a relatively new movement, the Abayudaya of Uganda have converted to Judaism since 1917, influenced by the American William Saunders Crowdy, who said that African Americans were descended from the Jews.
A number of European Jews settled in Northern Rhodesia (now Zambia). At its peak in the early 1960s, there were 1,000 Jews living in the country, many in Livingstone. The number began to fall after independence and there were estimated to be around 50 remaining by 2012.
The Zimbabwe Jewish Community was mainly of British citizenship, whose arrival coincides with the first white colonists in the 1890s. At its peak in the early 1970s, it numbered some 7,500 people (80% were of Ashkenazi descent), who lived primarily in the two communities of Salisbury and Bulawayo. Smaller rural communities also existed for short periods in Que Que, Umtali and Gatooma. The community declined in part due to age, but most Jewish residents in Zimbabwe left after violence and social disruption. In 2007, the local Jewish community had declined to 270. The community had strong links with Israel. In 2003, the Bulawayo Shul was burnt down in an anti-Semitic act of violence.
