The history of the church is closely related to that of the village. Around the year 1266, "broite inferior", the lower broad, was first mentioned. A small chapel was mentioned in 1293, which was a branch of the parish church in Ochsenfurt. At that time, a predecessor church already existed on the site of today's church. It was dedicated to Saint Nicholas.
On July 18, 1324, the church was elevated to the status of a parish. The Bishop of Würzburg, Wolfram von Grumbach, issued the parish letter. A short time later, in the first half of the 14th century, construction of the new church began. In 1409, Unternbreit came into the hands of the Lords of Seinsheim, who are said to have rapidly expanded the village. Engelhard von Seinsheim had the nave rebuilt in 1438 and designated the church as the burial place for his family.
In the middle of the 16th century, Lutheran ideas came to Unternbreit. Soon after, the Reformation was officially introduced in the village under Georg Ludwig von Seinsheim. The first evangelical preacher in the village is documented for 1543, since 1551 Unternbreit had an evangelical pastor. A few years later, the village received market rights and was renamed Marktbreit in 1557.[1] In 1567 the church was enlarged. In 1587 the raised church tower was fitted with a French dome
