The Rappenkrieg was a peasant uprising lasting from 1591–1594, involving a conflict between the Swiss city of Basel and the surrounding Prince-Bishopric of Basel.
At issue was an increase in the rate of sales tax on wine and meat. After several years the conflict was ended through negitiations headed up by the Basel merchant turned politician Andreas Ryff.
The name "Rappenkrieg" comes from the local word, Rappen, then as now the term for a low value coin: "Rappenkrieg" can be loosely translated as the "Pence/Cents War".
The Basel Rappenkrieg is not to be confused with the Rappenkrieg in Western Austria from 1612 to 1614 in the adjacent Fricktal and the Rhine, although both had similar causes.
The Rappenkrieg was a conflict that lasted from July 1612 until September 1614 in the Further Austrian district of Breisgau. It involved the Austrian rulers putting down a peasant uprising. The uprising occurred in what is now the Swiss Canton of Aargau and in the southern portion of what is now the German State of Baden-Württemberg. It is not to be confused with the Rappenkrieg in Basel-Stadt, Switzerland (1591–1594), although it had similar causes.
