Philipp I of Katzenelnbogen (1402 - 1479), also known "Philipp the Elder" was Count of Katzenelnbogen from 1444 to 1479 and was the last male descendant of the Counts of Katzenelnbogen (his two sons died before him). His parents were Johann IV, Count of Katzenelnbogen (younger line) and Anne of Katzenelnbogen (older line), who merged the two lines of the family back together in 1402.
Philip married on 24 February 1422 in Darmstadt Anna of Württemberg (1408–1471),[1] daughter of Eberhard IV "the Younger" of Württemberg. In 1456, he obtained from the Pope a divorce a mensa et thoro.[2] In 1474 Philip married Anne of Nassau-Siegen.[3] Philipp had three children with his first wife:
Philipp's sons Eberhard and Philipp the younger died before his death, so when Philipp died in 1479, the Katzenelnbogen family died out in the male line. The County of Katzenelnbogen fell to the Landgraviate of Hesse, which was ruled at the time by Philipp's son-in-law Henry III of Hesse in Marburg, Henry having bought off the inheritance rights of Philipp's granddaughter Ottilie.
