John Henry IV of Gorizia

John Henry IV of Gorizia (1322–1338), the only son of Count Henry III and Beatrix of Lower Bavaria, succeeded his father in 1323 as an infant. His mother, uncle Albert II and, after 1329, cousin Albert III acted as regents. In 1332, aged nine, Trieste elected him its podestà against Venetian expansion.

His betrothal to Beatrice of Sicily was cancelled in 1335; by the treaty of Ljubljana he married Anna of Habsburg, daughter of anti-king Frederick the Fair, in a childless marriage. He died in 1338 and was buried at Rosazzo Abbey, succeeded by Albert II's sons.
