Baldwin III of Jerusalem
The first and maybe the most famous of all Sandomierz's dukes, Henry certainly ventured to the Holy Land in 1153-1154 (a number of Polish annals reported it under the year 1154 as did Jan Długosz in his Annals) and took part in the Second Crusade under the command of King Baldwin III of Jerusalem. Henry close affiliation to crusading resulted in the establishment of a commandery of the Hospitallers (between 1154 and 1166) in Zagość.
