War in Rome

After King Henry IV of Germany and Pope Gregory VII clashed over several issues, Henry decided to depose Gregory and put Guibert of Ravenna on the Throne of Peter as (antipope) Clement III. Henry promised to bring his army to Rome to accomplish this, but failed in his first attempt in 1081. A later attempt succeeded, however.

Henry marched into Rome on 21 March 1084. Pope Gregory barricaded himself in the Castle Sant'Angelo, which meant abandoning the papal complex. Three days later, Clement III took possession of the papacy. In return, he crowned Henry as Holy Roman Emperor.

Gregory had allies, however, one of whom was the powerful King of Sicily, Robert Guiscard. Robert brought his Norman army to Gregory's aid, prompting Henry and Guibert to abandon Rome. On their way north, Henry ravaged parts of Tuscany which were possessions of Matilda of Tuscany, who had supported Gregory. Guibert went to Ravenna, where he had been archbishop, and wielded limited power.

Although Gregory was free to resume his job as pope, Romans were upset at damage done by his Norman allies. Opposition to Gregory grew great enough that he decided to live at Monte Cassino. He died a year later, on 25 May 1085. His immediate successor (Victor III) did not relish the public life of the papacy, and did not last long before he retired. His successor was Urban II, who also had problems because of German support (and some in Rome) for Clement. Clement returned to Rome in 1089, taking up residence at the Vatican and forcing Urban to stay away from Rome.

The King of France's brother, Hugh of Vermandois, marched on Rome to deal with the antipope, prompting Clement this time to flee to Monte Cassino. Hugh captured Monte Cassino as well, however, and Clement fled to Albano, a day's journey from Rome. By this time, however, Urban had died, and Paschal II was the pope of the anti-Germany faction.

Guibert/Clement died on 8 September 1100, having outlived two popes who were his opposition and who failed to depose him. His supporters elected another antipope, Theodoric, who never wielded any real authority and lasted a year.

Who was this Matilda of Tuscany, who supported Gregory and suffered because of Henry IV? Let me tell you about la Gran Contessa tomorrow.

Emperor Alexios I Comnenos

Alexios I Comnenos (1057 - 1118) was the Byzantine emperor during the start of the Crusades. Since the Byzantines were a part of the old Roman Empire, and Christian, and a well-populated and economically significant city at the eastern end of the Mediterranean, Europeans saw them as allies and the gateway to the lands of the infidels who held the Holy Land.

The Crusades were not his only concern, however. As a young man, he and his brother, Manuel Comnenos, served with distinction against the Seljuk Turks, whose territory was right across the Bosporus. The empire also had trouble with Normans in the western Balkans. At one point, he refused to fight against a kinsman who was seizing control of Byzantine territory in Asia Minor for himself. This did not count against Alexios, however, because his abilities were too valuable, and he was needed to help deal with Robert Guiscard.

His father, John Comnenos, had refused the throne when the previous ruler, Isaac I Comnenos, abdicated to become a monk. The throne therefore went to Constantine X Doukas, followed by Romanos IV Diogenes, then Michael VII Doukas, then Nikephoros III Botaneiates, against whom Alexios conspired to take the throne himself. Alexios surrounded Constantinople with his troops, broke through the walls on 1 April 1081, and was crowned on 4 April. Nikephoros fled, but was captured and forced into monk-hood.

Alexios took on an empire that was in decline and face with content military threats at the edge of its borders. Alexios' military skills enabled him to strengthen the empire and recover lost territory. The First Crusade was sparked by his requests for aid against the Turks, as mentioned in this 2012 post. He got the help (some of which was better than others), but the Seljuks continued to be a problem throughout his reign. He was also plagued by the question of succession, his preference being for his son John II Comnenos, while his wife pushed for their daughter Anna and her husband.

I might get to the resolution of who succeeded Alexios, John or Anna, but I want to talk about another Anna: Alexios' mother. She was an important figure who had a significant role in helping his rebellion succeed, and we should look at her next.
