Bremgarten is a Swiss district in the Canton of Aargau, that is essentially the area of the northern Freiamt in the valleys of Reuss and Bünz that are covered.
In the seventeenth century, or probably at an earlier period, when the Jews were banished from the confederation, several Jewish families were collected here under special protection as "Schirmund Schutzjuden." They were, however, forbidden to buy land or to own houses, and they were not permitted to live under the same roof with Christians.
The provost and the district clerk and his secretary received "recognition money" and "settlement dues"; and whenever the Jews passed through a locality in the canton they paid a polltax.
In 1712, when the Jews at Lengnau were pillaged by the country people, the former had their charter renewed for sixteen years, and again, at its recurrent expiration, in 1728, 1744, and 1760—on the last occasion even in spite of the subprovost's urgent demands that they be banished.
