Summary

The American Cyclopædia — Charles IX.…

Sigismund being a Catholic, and bitterly hostile to Lutheranism, which had been introduced into Sweden by Gustavus Vasa, Charles, by the consent of the senate, assumed the government, and a decree was passed that Lutheranism should be the only religion of Sweden, and that Sigismund should not be recognized as king until he had signed the decree. This he did, and was crowned in 1593, but he became obnoxious on account of the favor which he manifested to Catholicism. There was also a party, led by Charles, opposed to a union of the crowns of Poland and Sweden.
