The history of the village Mallersdorf goes back to the Roman times, because the first castle, named "Madilhardisdorf" had been established on the foundation of a Roman fort. The name goes back to Mathilde von Lupburg, the 9th abbess of the Reichsstift Niedermünster in
Regensburg who owned extensive estates in the area. During the
Carolingian's time Mallersdorf belonged to the county of Kirchberg. The counts Heinrich and Ernst donated a cloister in 1107, which was first mentioned in a document in 1129, with the confirmation of the donation by emperor
Lothar III. The Latin school, which was controlled by Benedictine monks in the
cloister of Mallersdorf on the Johannisberg, operated there from 1109 to 1803. Mallersdorf gained a great reputation in the scientific area due to its large library. The honorary title "sedes sapientiae" (seat of wisdom) testifies this position. In the course of the Säkularisation the cloister was converted into a farm with brewery. The library, as well as valuable sacred objects, was brought to
Munich. The cloister had a resurgence in 1869 as a franziscan order, the "Sisters of Mallersdorf"( established her mother's house there.) In 1972 the places Mallersdorf, Pfaffenberg, Holztraubach, Ascholtshausen, Oberellenbach, Oberlindhart were united to the market Mallersdorf-Pfaffenberg. The municipalities of Niederlindhart, Haselbach and Upfkofen came on 1 January 1978. On 1 July 1972 Mallersdorf lost the District's Office and came to the administrative district
Straubing-Bogen. Therefore, the sign MAL disappeared mainly from the streets. ==Partnership==
