Input: Question: How much older was Emperor Heinrich's father than he was when he was taken prisoner in Ingleheim? Passage:The old name forms of Waldböckelheim (now a neighbouring municipality), Schloßböckelheim and Talböckelheim (now an outlying centre), can be traced back to an 824 document that names . The name Schloßböckelheim first cropped up only in the 17th century. In the 19th century, the name Thalböckelheim first came to light. On 1 November 1910, municipal council agreed to introduce Schloßböckelheim as the municipality's name. The name Talböckelheim seems to have had its spelling changed in line with the spelling reforms over the years; it is now written without the first H, but the name Schloßböckelheim itself has not been changed in the wake of the German orthography reform of 1996; the ß has not been changed to SS. The three prefixes that serve to distinguish the three centres whose names are otherwise the same are all standard German words with well understood meanings: Wald (“forest”); Schloß (or Schloss in up-to-date spelling; “castle/palace”); Tal (“dale/valley”). The village chronicle has this to say about the village's name:Until the beginning of the last century (meant here is the 19th century) the village was named after the castle Schloßböckelheim, which still existed in the 17th century. The castle was destroyed by the French in 1688. The village of Thalböckelheim consists of the two constituent centres of Thalböckelheim and Schloßböckelheim: Schloßböckelheim with the ruin of Castle Böckelheim lies on the mountainside and the constituent centre of Thalböckelheim lies 0.5 km away down in the dale. Both constituent centres have roughly the same population figure. The village’s name was changed in quite a peculiar way. In the early part of the last century, in response to an inquiry by the authorities as to what the village was called, because it consisted of two constituent centres, the name Thalböckelheim was given by the then Schöffe (roughly “lay jurist”). The Schöffe lived in the constituent centre of Thalböckelheim and a certain selfishness on his part made him want to call the village Thalböckelheim, without regard to the historical importance of the constituent centre of Schloßböckelheim. None of the locally customary rural cadastral names had to do with the name Thalböckelheim, but rather they were named after Schloßböckelheim, like Schloßböckelheimer Mühlberg, Schloßböckelheimer Felsenberg, Schloßböckelheimer Kupfergrube and so on. Wines had earned quite an important reputation as Schloßböckelheimer in the wine trade, whereas Thalböckelheim never cropped up in the wine trade. Municipal council asked on these grounds to have the historical name Schloßböckelheim reinstated, as it was already well known throughout Germany for Emperor Heinrich IV’s imprisonment at Castle Böckelheim (1105).Also given as grounds for the reversion to the older name was the name's recognizability in winegrowing and the wine trade. A decree made on 22 April 1911 approved the municipality's application. Since this time, the two constituent centres of Thalböckelheim and Schloßböckelheim have been united under the collective name “Schloßböckelheim”. Among the places in the middle Naheraum (regions flanking the Nahe), Schloßböckelheim belongs among those places that were already often being mentioned in the Middle Ages. Castle Böckelheim, built on what was to become Schloßböckelheim's municipal area, was among the oldest in the region. Generally regarded as the village's first documentary mention is a document from 16 February 824. Late in 1105, Emperor Heinrich V, the last of the Salian dynasty, had his father, Emperor Heinrich IV taken prisoner in Ingelheim and then brought to Castle Böckelheim to be held prisoner there. In 1688, the Nine Years' War (known in Germany as the Pfälzischer Erbfolgekrieg, or War of the Palatine Succession) broke out. That year, the castle was destroyed on French orders.
