 At the turn of the 17th century, Unterselchenbach belonged to the church of Konken, as reflected in its belonging to the lordly domain of the Remigiusberg Monastery.After the Thirty Years' War, religious freedom was theoretically in force, although in practice the great majority of the population remained Protestant (Calvinist or Evangelical).In 1821, Unterselchenbach was transferred to the parish of Niederkirchen, but this arrangement was reverted only two years later.
