Walter I Grenier
Walter I Grenier was the Lord of Caesarea in the Kingdom of Jerusalem, succeeding his father Eustace. He was the twin brother of Gerard Grenier, Lord of Sidon. He was a member of the House of Grenier.
According to William of Tyre, Walter was "of fine appearance and famous for his strength." His mother Emelota remarried Hugh II of Le Puiset, a cousin of Queen Melisende, whose relationship with the queen was suspected of being "too familiar." Walter, prompted by Melisende's husband King Fulk, accused his stepfather of treason before the Haute Cour. Hugh denied the charge and it was decreed that the dispute should be settled by judicial combat, but Hugh did not show up on the appointed day; instead, he allied with the Muslim garrison at Ascalon and led a rebellion against Fulk. He was later sentenced to exile.
In 1148 Walter was present at the Council of Acre, where the nobility of Jerusalem met Louis VII of France and Conrad III of Germany and other European magnates who had arrived on the Second Crusade.
Walter married a woman named Juliane, and was succeeded by his son Hugh as lord of Caesarea.
