although much of calvin's practice was in geneva, his publications spread his ideas of a reformed church to many parts of europe. calvinism became the theology of most christians in scotland (see john knox), the netherlands, and parts of germany, and was influential in france, hungary, transylvania, and poland. calvinism was popular as well for some time in scandinavia, especially sweden, but was rejected in favor of lutheranism after the synod of uppsala in 1593.
