THE ROMAN BORDERS IN GERMANY

Isenburg Bundigen stretched throughout the region of Oberhessen and sud Hessen as a corridor similar to the one of Hannau. These regions are ancient in their history. Archeologists have unraveled extraordinary digs along the border that separated Germania of the Roman empire against the wall of Germanic tribes, which existed as far back as the destruction of the Second Temple.

That border was a man-made line called the "Obergermanisch-Raetischer Lines" (The Upper German-Raetian Limes). You can find a map of this enormous man made border at:

It separated the small communities of the empire including the central territory of the Wetterau and the small magistrates that became Dieburg, Butzbach and Friedberg, from the barbaric German tribes.

Little information exists about the region from 475 CE to 1076 CE, as the Roman empire began to crumble. With Charlemenge's ascent to power, however, Jews (said to be 10,000 in population), found themselves settled within the communities of Speyer, Mainz and Worms. These communities lay east of Hassia (the former name of Hessen) and along the central artery of Western Europe, the Rhine. Jews were finally given rights of settlement in 1076.

How these 10,000 people survived under relentless assault can only be called heroic. At the time of Maimonodes, the Jews of the north developed sophisticated systems of justice between themselves and the feudal overlords. They had three great Rabbis who developed a justice system that would lay the foundations for trade and capitalism. No one knows how the Hanseatic league developed their trade system. No doubt someone must have studied how the Jews handled their business dealings.

Jewish life changed after the pogroms of 1096 CE when the Crusades began. By 1188 CE and the start of the third Crusade, Jews left their Torah scrolls in the large communities and fled to the burgeoning villages and fortifications along all the tributaries of the Rhine. One of these fortifications was Munzenburg, a medieval castle some twenty kilometers north of Frankfurt. For example, the Wolfersheim cemetery, where Jews are buried, is five kilometers from Munzenburg castle.

By the fifteenth century, the principality was bought out by the Isenburg family. They had then begun to build castles in Bundigen, Birstein and through family alliances in Ronneburg and then later Assenheim, Wachterbach, Solms and Rodelheim. There is a famous Mikvah in Friedberg (@1250 CE), but there is also a Mikvah in AlteWiedemus, now just an ordinary-looking house some three kilometers east of the Ronneburg, but that castle also is home to existing Jewish graves. It is said they go back to the 16th century.

The Eckerthausen cemetery (some five kilometers from Ronneburg) was shared by people from that community, Langenbergheim and AlteWiedemus, after Jews left the castle walls. By the 17th century, the Isenburg-Bundigens began to fall into financial disrepair and sold their castle at Ronneburg to some Moravians who were fleeing Saxony religious oppression. Some Moravians claim that they converted Jews, but Lazarus Mai from Rodelheim along with his wife Caroline are buried in this cemetery. This lays further evidence that Jews connected themselves through the relations that the various Counts and princes had with each other. Thus Oberhessen with all its many small fiefdoms must have been particularly tolerant of Jewish travel since all its Princes needed trade to survive. That is why you can see Gruenbaums in Assenheim, in Meerholz, in Friedberg and throughout the region as well as Ienburgers and Sterns.
