Jews in Africa
There is also a group of native Jews in Uganda who descended from a group of Christians (presumably converted by missionaries at some point) who rejected Christianity and accepted observant Jewish practice in 1919. Fascinating.
Why this sudden interest in Africa? I just found out that a friend of mine is spending three weeks volunteering in Tanzania this summer, and I kind of want to join her. The volunteering program is not Jewish but would be Shabbat-friendly and kashrut-friendly. (You don't volunteer on weekends, and they feed you and are willing to purchase a new pot for my friend and help her find vegan food or rice and beans or whatever to cook for herself.) The drawback? It costs money. Doesn't everything?
