Although strategically significant, the capture of Lleida drew less attention than the siege of Tortosa the previous year, which involved international contingents as part of the Second Crusade.[5] At least one later source does, however, treat the 1149 siege as a crusade, attributing the victory "to the faith and worship of our Lord Jesus Christ".[6] No detailed contemporary account of the siege survives.[7]
In January 1150, Ramon Berenguer IV and Ermengol granted a municipal charter to Lleida.[8] Ramon Berenguer took the title marquis of Lleida and, acting as sovereign, granted the city to Ermengol in fief.[9]
