"The Icelandic Reformation took place in the middle of the 16th century. Iceland was at this time a territory ruled by Denmark, and Lutheran religious reform was imposed on the Icelanders by King Christian III of Denmark. The Icelandic Reformation ended with the execution of J\u00F3n Arason, Catholic bishop of H\u00F3lar, and his two sons, in 1550, after which the country adopted Lutheranism."@en . . . . . . . . .
