Ydre Municipality
Ydre Municipality (Ydre kommun) is a municipality in Östergötland County, southeast Sweden. The municipal seat is located in the town of Österbymo.

The municipality was created through the local government reform of 1952, when six former entities were united. The name was taken from the old Ydre Hundred. Its area remained unchanged by the reform of 1971.

The name Ydre, which was formerly applied to most of the area around Sommen, is interpreted to mean "place of yews". Two localities in particular appear to be further associated with yews these are Idhult and Idebo.

The rare and endangered flower Anthericum liliago can be found along the lake's rocky shores. This is one of the northernmost locales where it grows.

History

Trolls, jättar and Christianization
There are various tales of jättar and trolls opposing the spread of Christianity in Ydre. Likely church building followed a tradition that "the king" should begin the building, and then the local populace finish it. This was later codified in Östgötalagen. It is not known when the first churches around the lake were built. For comparison, the church in nearby Tidersrum was built in 1300, and Leonhard Fredrik Rääf asserts that the church in Sund was built in the 12th century.

Reformation and wars

As Nils Dacke's and his army advanced north through Ydre in 1542, local priests from Sund and Asby, and the populace in general, welcomed the rebellion as they were rejected church reforms imposed on them by Gustav Vasa. In particular, the priest of Sund and Norra Vi preached uprising. However local aristocrat Måns Johansson Natt och Dag who owned the manor of Ringshult sided with the king despite having a troublesome relation to him. He was put in charge of an army to suppress the rebellion. As Dacke's troops continued their advance north reaching as far as Mjölby the area around lake Sommen was spared from war. Skirmishes did occur near Kisa, tens of kilometers northeast of Sommen. Unrest in Ydre continued well after the death of Dacke and ended only after Gustav Vasa sent a force of 400 men to pacify the hundred.

Despite earlier defense of Catholicism at the Uppsala Synod in 1593 church representatives from Ydre voted to adopt the Lutheran creed.

Sights

At least two churches have medieval foundation: The Church of Asby in Asby, and the Church of Torpa on the countryside. There is also an attractive church from the 18th century, Church of Norra Vi, located just by the lake Sommen.

Another tourist attraction is Naturum Sommen in Torpön Island, a visitor center and natural history museum.
