Elisabeth's relationship to her firstborn son Conradin remained a reserved one. When Charles of Anjou defeated Manfred of Sicily in the 1266 Battle of Benevento, her brother Louis and her husband Meinhard encouraged Conradin's decision to go on campaign. In August 1267, mother and son met for a last time at Hohenschwangau Castle before Conradin left for Italy, together with his uncle and his stepfather, who however deserted him in Verona. After Elisabeth heard of his defeat and execution in 1268, she had the Santa Maria del Carmine Church erected in Naples in his memory. In 1272 she founded the Cistercian abbey of Stams in Tyrol, together with her husband Meinhard, where she is also buried.
