In the 1990s, a descendant of a Jewish settler undertook serious study of Judaism. He began to revive the practice of Judaism among his family, friends, and other Sephardi descendants. After years of study, with the help of a sympathetic Conservative rabbi in Lima and another from Brooklyn, New York, eventually a few hundred people studied, practiced as Jews, and converted to Judaism. (Formal conversion was necessary according to "Halakha" as their mothers were not Jewish.) Many of the converts have emigrated to Israel under its Law of Return. A documentary was made about this community in 2010. Emigration of Peruvians from this Iquitos community has continued; about 150 emigrated in 2013 to 2014.
