This practice has its roots in old Swedish legislation and was established by Birger Jarl in the 13th century, building upon the Truce of God tradition.
[2] The tradition of Christmas Peace has survived in Finland, which was part of Sweden from the late 13th century until 1809.
The statement intimates the possibility of stricter sanctions for infringements committed throughout the festive season, yet its legal effects have not been enforced since 1889.
It begins with the hymn A Mighty Fortress Is Our God and is followed by the Declaration, which is read at noon by a city official.
The event ends with the March of the Men of Pori, usually played by a local military band, usually from the Finnish Navy.
[8] English translation of the Turku Declaration of Christmas Peace:[1] Tomorrow, God willing, is the graceful celebration of the birth of our Lord and Saviour;
Besides Turku, the declaration is also announced in some of the oldest Finnish towns like Rauma, Porvoo and Pori.
The tradition dates back to the 17th century, during the reign of Queen Christina of Sweden, when a unique peace was occasionally declared even in the most adverse circumstances.
