How many Anabaptists were there?

Place-by-place counts (Bern, the 1711 trip, the Palatinate, the Jura, France, the Netherlands, Prussia, Russia, America): Anabaptist population by place.

Counted numbers are rare before 1700 — Anabaptists were illegal and kept no public registers. Bold = an actual count.

What it means: founding populations were tiny, which is why the same ancestors recur (Double ancestors). Two of the three streams are already traced almost completely: GRANDMA for the Low German Mennonites (GRANDMA database) and Gingerich & Kreider for the 18th-century Amish (Amish and Amish Mennonite Genealogies (Gingerich and Kreider)). The Swiss stream needs Bern’s handwritten lists (Bern Taeuferakten (Anabaptist files)).

Supporting documentation is linked throughout. This project is an exercise in AI-assisted research and development, and I haven’t manually verified every link or conclusion. All transcriptions and translations of Swiss parish records were made with AI, and their accuracy should be treated accordingly.
