Engelbert was the eldest son of Siegfried I, Count of Sponheim and Richardis of Lavant, heiress of Count Engelbert IV.[1] In 1065 he followed the Zeisolf-Wolframs as a count in the Kraichgau,[2] from 1070 he is documented as a count in the Pustertal.[3] In the Investiture Controversy he belonged with his brothers to the party of the South Germans supporting Pope Gregory VII and, as a supporter of the Archbishop of Salzburg, Gebhard von Helfenstein, fought in the years 1085 and 1086 against the imperial appointed counter-bishop Berthold von Moosburg.[4] In 1086 he succeeded in bringing Archbishop Gebhard back to Salzburg from exile.[5] As a result of his position in the Investiture Controversy, Engelbert was relieved of the district of Pustertal by Emperor Henry IV in 1091, which the Emperor then gave to the Bishop Burkhard von Brixen.[6]
On 1 May 1091, Engelbert founded the Benedictine monastery of St. Paul,[7] inhabited by monks from Hirsau and their Abbot Wezilo. This monastery became the house monastery of the Sponheimers, who continued to give it rich gifts. It is also the oldest burial sites of the House of Sponheim and their descendants are found there.
In April 1095 Engelbert joined St. Paul monastery as a monk.[8] He died there on 1 April 1096.[8]
