Henry V (German: Heinrich V.; probably 11 August 1081 or 1086 – 23 May 1125) was King of Germany (from 1099 to 1125) and Holy Roman Emperor (from 1111 to 1125), as the fourth and last ruler of the Salian dynasty. He was made co-ruler by his father, Henry IV, in 1098.
In Emperor Henry IV's conflicts with the imperial princes and the struggle against the reform papacy during the Investiture Controversy, young Henry V allied himself with the opponents of his father. He forced Henry IV to abdicate on 31 December 1105 and ruled for five years in compliance with the imperial princes. He tried, unsuccessfully, to withdraw the regalia from the bishops.
