Limburg an der Lahn, Germany

One line of the Lords of Ysenburg resided from 1258 to 1406 at Limburg Castle and took their name from their seat, Limburg. From this line came the House of Limburg-Stirum and also Imagina of Isenburg-Limburg, the wife of the German King Adolf.

The ruling class among the mediaeval townsfolk were rich merchant families whose houses stood right near the castle tower and were surrounded by the first town wall once it was built. The area of today's Rossmarkt ("Horse Market"), in which many simple craftsmen lived, was only brought within the fortifications once the second town wall was built. The inhabitants there, however, unlike the merchant élite, were accorded no entitlement to a voice in town affairs and were not allowed to send representatives to the town council. Nevertheless, they had to bear the main financial burden of running the town. Only in 1458 were they allowed to send two representatives to town council.

Saint George's Cathedral (Sankt-Georgs-Dom) built on the old monastery church's site, and also called Georgsdom, was consecrated in 1235. On 14 May 1289, a devastating fire wiped out great parts of the inner town, although these were subsequently rebuilt. One of the houses built at that time was the Römer 2-4-6, which is today one of Germany's oldest half-timbered houses. In 1337, Limburg's Jews were expelled from the town. Only in 1341 were they once again able to settle in the town, by royal decree. In 1344 a half share of the town was pledged to the Electorate of Trier, and in 1420, the town passed wholly into the ownership of Trier. This event, along with another town fire in 1342, the Black Death in 1349, 1356 and 1365, but above all the rise of the Territorial Princes, led to a gradual decline. In 1315 and 1346, the old stone Lahn Bridge was built (presumably in two sections).

Against the background of the German Peasants' War, unrest also arose among the townsfolk in 1525. After the Elector of Trier had demanded that the townsmen turn a Lutheran preacher out of the town, a board made up of townsmen who were ineligible for council functions handed the council a 30-point comprehensive list of demands on 24 May. It dealt mainly with financial participation and equality in taxation, trade and building issues with the merchant class. In the days that followed, these demands were reduced in negotiations between the council and the board to 16 points, which were likely also taken up with the Elector afterwards. On 5 August, however, Archbishop Richard ordered the council to overturn all concessions to the townsmen. Furthermore, a ban on assembly was decreed, and the ineligible townsmen were stripped of their right to send two representatives to council.

In 1806, Limburg came into the possession of the newly founded Duchy of Nassau. In 1818 the town wall was torn down. In 1827 the town was raised to a Catholic episcopal seat. In 1866 the Duchy and with it Limburg passed to Prussia in the wake of the Austro-Prussian War. As of 1862, Limburg became a railway hub and from 1886 a district seat. In 1892, the Pallottines settled in town, but only the men; the women came in 1895.

During World War I there was a major prisoner of war camp at Limburg an der Lahn. Many Irish members of the British Army were interned there until the end of the war and at one stage they were visited by the Irish republican leader Roger Casement in an attempt to win recruits for the forthcoming Irish rebellion.

From 1919 to 1923, Limburg was the "capital" of a short-lived state called Free State Bottleneck (or Freistaat Flaschenhals in German) because during the Allied occupation of the Rhineland it was effectively cut off from the Weimar Republic in an area the shape of a bottle's neck and subsequently separated from its administration.

In August 1939, shortly before the German invasion of Poland and start of World War II, the German Army established the Dulag G prisoner-of-war camp for Polish POWs in the town. The camp was dissolved in January 1941.
