Within the framework of municipal reform in Hesse in 1972, two greater communities were founded in the Fulda valley, the
Besengrund and the neighbouring valleys north of
Bad Hersfeld. After a short time, these areas, along with further villages that until now had been self-administering, were melded into the greater community of Ludwigsau. The community's namesake is Landgrave
Ludwig I of Hesse, who had two castles built within what are now municipal limits, Schloss Ludwigseck and Ludwigsaue Castle (built in 1416). Of the later, no trace is to be found today. It stood, however, at the mouth of the Rohrbach, where it empties into the
Fulda.
Amalgamations With effect from 31 December 1971, the community of Ludwigseck came into being through the voluntary merger of the formerly self-administering communities of Beenhausen, Ersrode, Hainrode and Oberthalhausen. At the same time, the community of Ludwigsau came into being through the voluntary merger of the formerly self-administering communities of Biedebach, Friedlos, Gerterode, Meckbach, Mecklar, Reilos, Rohrbach and Tann. Friedlos in particular was interested in a forcible merger with the district seat of Bad Hersfeld. Since Niederthalhausen had come out against a merger with Ludwigseck, in the course of municipal reform on 1 August 1972 – after only seven months of existence – the community of Ludwigseck was dissolved and the whole municipal area, along with Niederthalhausen, was forcibly merged with the greater community of Ludwigsau. ==Politics==
