Balian of Ibelin (; ), also known as Barisan the Younger, was a crusader noble of the Kingdom of Jerusalem in the 12th century. He was lord of Ibelin from 1170 to 1193. As the leader of the defense of the city during the siege of Jerusalem in 1187, he surrendered Jerusalem to Saladin on 2 October 1187. Early years Balian was the youngest son of Barisan of Ibelin, and brother of Hugh and Baldwin. His father, a knight in the County of Jaffa, had been rewarded with the lordship of Ibelin after the revolt of Hugh II of Le Puiset. Barisan married Helvis of Ramla, heiress of the wealthy lordship of Ramla. Balian's name was also Barisan, but he seems to have adapted the name to the Old French "Balian" c. 1175–76; he is sometimes known as Balian the Younger or Balian II when his father is also referred to as Balian. He is also called Balian of Ramla or Balian of Nablus. In Latin his name appears variously as Balian, Barisan, Barisanus, Balianus, Balisan, and Balisanus. Arabic sources call him Balian ibn Barzan which translates "Balian, son of Barzan." His precise year of birth is unknown, but he was of the age of majority (usually 15) by 1158, when he first appears in charters, having been described as under-age ("infra annos") in 1156. After the death of Balian's eldest brother Hugh c. 1169, the castle of Ibelin passed to the next brother, Baldwin. Baldwin, preferring to remain lord of Ramla, gave it to Balian. Balian held Ibelin as a vassal of his brother, and indirectly as a rear-vassal of the king, from whom Baldwin held Ramla. Succession disputes Baldwin supported Raymond III of Tripoli over Miles of Plancy as regent for King Baldwin IV in 1174, and in 1177 the brothers were present at the Battle of Montgisard, leading the vanguard victoriously against the strongest point of the Muslim line. That year Balian also married Maria Comnena, widow of King Amalric I, becoming stepfather to Amalric's younger daughter Isabella. He received the lordship of Nablus, which had been a dower gift to Maria following her marriage to Amalric. In 1179, Baldwin of Ramla was captured by Saladin after the Battle of Jacob's Ford, and Balian helped arrange for his ransom and release the next year; the ransom was eventually paid by Byzantine emperor Manuel I Comnenus, Maria's great-uncle.
