In 788, the Mattons transfer significant parts of their inheritance to the monastery in Fulda, including property "in the Grabfeld district in the village called Wenkheim". At around the same time, Matto and his sister handed over the church, monastery and substantial manorial estate (with 62 unfree) in the Wenkheim Mark to the Fulda monastery. Today, it is impossible to determine where the Wenkheim monastery once stood. Settlers lived in the Wannig catchment area thousands of years before the birth of Christ. The clearing islands they created in the wooded area formed the scattered settlement of the "Uuangheimero marcu", the Wenkheimer Mark, around 800, from which several settlement centers developed over time. By the 13th century at the latest, a distinction is made between the villages of Kleinwenkheim (Weynckheim minor) and Großwenkheim (Maiori Weinghem), and the districts are clearly demarcated. The development of Kleinwenkheim is largely determined by two external events. Count Palatine Hermann von Stahleck founded the Cistercian monastery Maria Bildhausen north of Kleinwenkheim in 1156/1157 on his own estate, the place first documented as "Bilihildehuse" around 1140. Around 1180, Kleinwenkheim was ecclesiastically assigned to the mother parish of Wermerichshausen, which belonged to Bildhausen and was later exchanged to a monastery in Aschaffenburg. The monastery in Fulda is still the lord of "die 17 Höf", while Count Otto von Botenlauben of Henneberg is the feudal lord. He exchanges his own property for Kleinwenkheim and donates the village of Kleinwenkheim to Maria Bildhausen Monastery in 1219. The parish priests of Wermerichshausen and the Maria Bildhausen monastery dominated life in the village. In 1525, Kleinwenkheim farmers also joined the Bildhausen mob that took over the monastery. The uprising ends in bloodshed and Kleinwenkheim remains a monastery village until secularization in 1803. At the end of the 16th century, the old little church outside the village in the damp ground of the Wannig is very dilapidated. In 1588/89, the people of Kleinwenkheim used the stones from the old church to build a new church on the northern edge of the village, which was not consecrated until 1615. From 1618, the great "German War" devastates the abbey and village. Napoleon ends the subsequent heyday of the mighty monastery with its magnificent church. The abbey is dissolved in 1803 and the monks are expelled. The church, built around 1180, and other buildings were demolished and the entire monastery complex sold. Two of the magnificent altars make their way to Kleinwenkheim. Today they are a valuable treasure in the village's St. Nicholas Church, which has been extended and redesigned several times. From 1814, Kleinwenkheim, like the whole of Franconia, belongs to the Kingdom of Bavaria. In 1803, together with other municipalities, it was assigned to the district court of Münnerstadt, and in 1862 to the district office of Bad Kissingen. The parish of Kleinwenkheim is established in 1871 with the inheritance of Dr. Severin Illig, who was born in Kleinwenkheim. In 1951, Maria Bildhausen and Rindhof are incorporated into Kleinwenkheim. A well-known company creates new jobs. In 1966, the town is connected to the Münnerstadt water supply. In 1971, the municipal council under Mayor Markus Glückert unanimously decides to incorporate Kleinwenkheim into Münnerstadt. The citizens follow this decision in a secret ballot with an overwhelming majority. Kleinwenkheim has been a district of Münnerstadt since January 1, 1972. Sewers and roads are built, the village is connected to the "Obere Lauer" sewage association, the cemetery is landscaped and a clubhouse is set up. New building areas are quickly settled. The village renewal that began in 1982 changed the face of the village: the old school became a community center, the thoroughfare and inner village streets were expanded. Renovated buildings, suitable gates and fences, old and new village fountains, the village square, a new fire station, the very active club life - Kleinwenkheim is a modern village with a rich past.
