1946. On 1 August 1947, Aalen was declared Unmittelbare Kreisstadt ("immediate district town"), and with the creation of the Gemeindeordnung (municipal code) of Baden-Württemberg on 1 April 1956, it was declared Große Kreisstadt. Religions On 31 December 2008, 51.1 percent of Aalen were members of the Catholic Church, 23.9 percent were members of the Evangelical-Lutheran Church. About 25 percent belong to other or no religious community or gave no information. The district of Waldhausen was the district with the highest percentage of Roman Catholic inhabitants at 75.6 percent, and the central district was the one with the highest percentage of Evangelical-Lutheran inhabitants at 25.6 percent, as well as those claiming no religious preference at 32.5 percent. Protestantism Aalen's population originally was subject to the jus patronatus of Ellwangen Abbey, and thus subject to the Roman Catholic Diocese of Augsburg. With the assistance of the Duke of Württemberg, in 1575, the reformation was implemented in Aalen. Subsequently, Aalen has been a predominantly Protestant town for centuries, with the exception of the years from 1628 until 1632 (see reformation section).

As Aalen's population grew in the 20th century, more parishes were founded: St. Mark's parish with its church building of 1967 and St. Martin's parish with its church of 1974. In the borough of Unterrombach, Aalen had implemented the reformation as well, but the community remained a chapel-of-ease of Aalen. A proper church, the Christ Church, was erected in 1912 and a proper parish was established in 1947. In Fachsenfeld, the ruling family of Woellwarth resp. of Leinroden implemented the reformation. A parish church was built in 1591, however with an influx of Catholics in the 18th century, a Catholic majority was established.
