Isabella I of Jerusalem

With the death of Queen Sibylla of Jerusalem during the Siege of Acre, her husband, Guy of Lusignan, lost his claim to the throne and the succession fell to Sibylla's younger sister, Isabella, currently in her late teens. Just as the leaders of Jerusalem objected to Guy's marriage to Sibylla, Isabella's husband was not considered the proper person to become King of Jerusalem simply by his marriage to the rightful queen.

Humphrey IV of Toron was a leading baron of Jerusalem. He and Isabella married in 1183 (the illustration shows the two being betrothed by Baldwin IV), and Humphrey gave Toron to King Baldwin IV (Isabella's half-brother) at the time. The other barons of Jerusalem were willing to give Humphrey and Isabella the opportunity to become king and queen after the death of Baldwin V because they did not want Guy on the throne, but the young married couple chose instead to pay homage to Sibylla and Guy.

Now, in the midst of an ongoing conflict with Saladin, an experienced military leader would be ideal as the new King of Jerusalem, and Humphrey did not fit the bill. There was someone who already wanted th throne, and was a tried and true military leader: Conrad of Montferrat. Isabella's step-mother, Maria Comnena—also the result of the nobles forcing someone to annul their marriage if they wanted to rule—supported the idea of Conrad marrying Isabella. Humphrey, she felt, had prevented Isabella from becoming queen once, and Maria was happy to see him out of the family.

Maria swore before a papal legate, Archbishop Ubaldo of Pisa, that Isabella's betrothal at the age of eight was against her consent and the marriage should be annulled. Patriarch Heraclius of Jerusalem deferred the matter to Archbishop Baldwin of Canterbury. Baldwin would not support the annulment, saying that Conrad and Isabella would be guilty of adultery. On the other hand, Archbishop Ubaldo supported the annulment after some concessions to Pisa were made.

Isabella made it clear that Humphrey (of whom she seemed fond) should not lose everything, and the lordship of Toron was restored to him. Isabella and Conrad were married on 24 November 1190. Conrad took her back to Tyre. Guy stayed at Acre. Guy refused to concede the kingship. What they needed was to gather more of the nobles of Europe and have the matter adjudicated by a gathering of peers.

Fortunately, more of the heads of Europe were on their way. We'll see how things went next time.

The Siege of Acre, Part 4

The first big clash between the army of Saladin and the Christians besieging the city of Acre led to thousands of losses for the Christians under Guy of Lusignan in September 1189. Fortunately, what became known as the Third Crusade had been called in Europe, and reinforcements started to arrive.

One of the imminent arrivals was Holy Roman Emperor Frederick I, known as Barbarossa. His reputation boosted the morale of those at Acre, but also motivated Saladin to call for many more soldiers to join him. Unfortunately for all concerned, Frederick drowned while taking a shortcut across the Saleph River in southern Turkey (see illustration), never making it to Acre. Two-thirds of his army returned home. The rest followed Frederick's son, Frederick IV of Swabia, to Acre. (They carried the body with them, intending for Barbarossa to be interred in Jerusalem. Preservation attempts with vinegar failed, and he was buried in Antioch.)

In the last days of October, a fleet of Muslim ships broke the Christian ships blockading the harbor to prevent Muslim reinforcements reaching Acre. Weapons, food, and 10,000 Muslims entered Acre from the sea. An Egyptian fleet arrived in mid-December, reinforcing the new blockade to prevent Christian ships from attacking from the sea.

Conrad of Montferrat sailed back to Tyre to bring back food and supplies for the Crusade army. He also brought materials to build siege machines.

Saladin added to his army over the months of winter, and attacked the Crusaders on 20 May 1190. The Crusaders resisted for eight days until finally Saladin's forces retreated.

During the summer, numerous nobles from Europe arrived with more men and supplies. Unfortunately, Saladin's forces had them almost completely surrounded, making further supplies and food scarce. An attack by some restless Christian soldiers against the orders of the leaders failed. Louis III of Thuringia contracted malaria, and headed home only to die in Cyprus. Between July and October Queen Sibylla died a few days after her daughters died. Guy, only King of Jerusalem through marriage to the rightful heir Sibylla, lost his claim to the throne, but refused to step aside for the next in line, Sibylla's younger sister, Isabella of Jerusalem.

Isabella's marriage was an issue, since she was now Queen of Jerusalem and her husband would be its king. She was already married, but her current husband was considered not the ideal person to be king, and so in the midst of the Siege of Acre there was some political meddling. We'll look at that tomorrow.
