Livestock markets were still being held at the outbreak of the Second World War on the "Sauwasen" (the plot of land where the primary school now stands), and each year, there is still a craft market on Kermis Tuesday. Rheinböllen's landholders changed often in the 14th and 15th centuries. Under the 1338 Palatine Partition among Rudolf II, Rupert the Younger and Rupert the Elder, the lordship over Rheinböllen changed once again: the two Ruperts – their name was "Ruprecht" in German – became the new lords. In the same year, King Louis forwent all claims to, among other things, the "half" of Rheinböllen, referring the pledgeholders, John of Bohemia and Archbishop Baldwin, to Count Palatine Rudolf and the two Ruperts. In 1352, Rupert I, Elector Palatine enfeoffed the Electorate of Trier with half of Rheinböllen. The court at Rheinböllen existed already by 1359 and was held on the plot of land where the Catholic church now stands. On the neighbouring "Henkersbitz" (Henker is German for "hangman") stood the gallows. In 1886, when excavation was being done for the church that was to be built there, workers unearthed, among other things, bones and skulls – all that was left of those hanged on the "Henkersbitz". About 1400, the Counts Palatine had enfeoffed several knightly families with parts of their Rheinböllen holdings, namely the families Knebel von Katzenelnbogen, von Crampurg, von Leyen, Futtersack von Steeg, Breitscheit von Richenstein and Hune von Bacharach. Even a family called the Knights of Rymbulle (Rheinböllen) crop up in documents from 1361 to 1389, although it is unknown whether or in what way they were linked with the town. Squire Dietrich von Rymbulle was also the fiefholder of the Sponheim Castle Kastellaun. Two centuries later, Rheinböllen belonged to the Electorate of the Palatinate and had 48 hearths (for which, read "households"). At that time in history, about 1600, many Palatinate lordships owned meadows within town limits: Anthonius Kratz von Scharfenstein, Antonius Waldbott zu Bassenheim, Friedrich Hundt von Seilen, Christoph von Stein, Hans Henrich von Schmidtburg zu Gemünden, Michel von Kallenfels, Hans Knebel von Katzenelnbogen, Hans Christoph von Grorode, the family von Koppenstein and Hans Caspar von Sponheim. At the end of the Middle Ages, Rheinböllen was a postal station on the route between Innsbruck and Mechelen, nowadays in Austria and Belgium respectively. An 18th-century geographical description explains that the road coming from Bacharach went through the market
