Norman conquest of southern Italy

The Normans' initial military involvement in southern Italy was on the side of the Lombards against the Byzantines. Eventually, some Normans, including the powerful de Hauteville brothers, served in the army of George Maniakes during the attempted Byzantine reconquest of Sicily, only to turn against their employers when the emirs proved difficult to conquer. By 1030, Rainulf became count of Aversa, marking the start of permanent Norman settlement in Italy. In 1042, William de Hauteville was made a count, taking Lombard prince Guaimar IV of Salerno as his liege. To further strengthen ties and legitimacy, Robert Guiscard also married Lombard Princess Sikelgaita in 1058. Following the death of Guaimar, the Normans were increasingly independent actors on the south Italian scene, which brought them into direct conflict with Byzantium.

During the time that the Normans had conquered southern Italy, the Byzantine Empire was in a state of internal decay; the administration of the Empire had been wrecked, the efficient government institutions that provided Basil II with a quarter of a million troops and adequate resources by taxation had collapsed within a period of three decades. Attempts by Isaac I Komnenos and Romanos IV Diogenes to reverse the situation proved unfruitful. The premature death of the former and the overthrow of the latter led to further collapse as the Normans consolidated their conquest of Sicily and Italy.

Reggio Calabria, the capital of the tagma of Calabria, was captured by Robert Guiscard in 1060. At the time, the Byzantines held a few coastal towns in Apulia, including Bari, the capital of the catepanate of Italy. In 1067–68, they gave financial support to a rebellion against Guiscard. In 1068, the Normans besieged Otranto; in the same year, they began the siege of Bari itself. After defeating the Byzantines in a series of battles in Apulia, and after two major attempts to relieve the city had failed, the city Bari surrendered in April 1071, ending the Byzantine presence in southern Italy.

In 1079–80, the Byzantines again gave their support to a rebellion against Guiscard. This support came largely in the form of financing smaller Norman mercenary groups to assist in the rebellion

Over a thirty-year period (1061–1091), Norman factions also completed the initial Byzantine attempt to retake Sicily. However, it would not be until 1130 that both Sicily and southern Italy were united into one kingdom, formalized by Roger II of Sicily.

First Norman invasion of the Balkans

Following their successful conquest of southern Italy, the Norman faction led by Robert Guiscard saw no reason to stop; Byzantium was decaying further still and looked ripe for conquest. Further pressing Norman motivation to invade was consistent support by the Byzantines for uprisings against Robert Guiscard. The Western edge of the Byzantine empire in particular was known for being a safe haven for rebel groups.

When Alexios I Comnenus ascended to the throne of Byzantium, his early emergency reforms, such as requisitioning Church money—a previously unthinkable move—proved too little to stop the Normans. Alexios suffered several defeats before being able to strike back with success. He enhanced this by bribing the German king Henry IV with 360,000 gold pieces to attack the Normans in Italy, which forced Guiscard to concentrate on his defenses at home in 1083–1084.

The Norman danger ended for the time being with the death of Robert Guiscard in 1085, combined with a Byzantine victory and crucial Venetian aid that allowed the Byzantines to retake the Balkans. Alexios had to grant the Venitians, and in general Italians, privileges to assure their support, something that eventually led to them controlling the empire's financial sector and eventually the Fourth Crusade.

Rebellion of Antioch

During the time of the First Crusade, the Byzantines were able to utilize, to some extent, Norman mercenaries to defeat the Seljuk Turks in numerous battles. These Norman mercenaries were instrumental in the capture of multiple cities. It is speculated that, in exchange for an oath of loyalty, Alexios promised land around the city of Antioch to Bohemond in order to create a buffer vassal state and simultaneously keep Bohemond away from Italy. However, when Antioch fell the Normans refused to hand it over, although in time Byzantine domination was established.

Second Norman invasion of the Balkans

In 1147 the Byzantine empire under Manuel I Comnenus was faced with war by Roger II of Sicily, whose fleet had captured the Byzantine island of Corfu and plundered Thebes and Corinth. However, despite being distracted by a Cuman attack in the Balkans, in 1148 Manuel enlisted the alliance of Conrad III of Germany, and the help of the Venetians, who quickly defeated Roger with their powerful fleet.

In ca.1148, the political situation in the Balkans was divided by two sides, one being the alliance of the Byzantines and Venice, the other the Normans and Hungarians.

Manuel I's invasion of Italy

The death of Roger in February 1154, who was succeeded by William I, combined with the widespread rebellions against the rule of the new King in Sicily and Apulia, the presence of Apulian refugees at the Byzantine court, and Frederick Barbarossa's (Conrad's successor) failure to deal with the Normans encouraged Manuel to take advantage of the multiple instabilities that existed in the Italian peninsula

He sent Michael Palaiologos and John Doukas, both of whom held the high imperial rank of sebastos, with Byzantine troops, 10 Byzantine ships, and large quantities of gold to invade Apulia. With the help of disaffected local barons including Count Robert of Loritello, Manuel's expedition achieved astonishingly rapid progress as the whole of southern Italy rose up in rebellion against the Sicilian Crown, and the untried William I.

William and his army landed on the peninsula and destroyed the Greek fleet (4 ships) and army at Brindisi on May 28, 1156 and recovered Bari.

Third Norman invasion of the Balkans

Although the last invasions and last large scale conflict between the two powers lasted less than two years, the third Norman invasions came closer still to taking Constantinople. Then Byzantine Emperor Andronikos I Komnenos had allowed the Normans to go relatively unchecked towards the Tessalonica.

Upon gaining control of the city Norman forces sacked Thessalonica. The following panic resulted in a revolt placing Isaac II Angelos on the throne. In the aftermath of the fall of Andronikos, a reinforced Byzantine field army under Alexios Branas decisively defeated the Normans at the Battle of Demetritzes.

Aftermath

With the Normans unable to take the Balkans, they turned their attention to European affairs. The Byzantines meanwhile had not possessed the will or the resources for any Italian invasion since the days of Manuel Comnenus. After the third invasion, the survival of the Empire became more important to the Byzantines than a mere province on the other side of the Adriatic Sea.

    I'm currently in that process. Very much a cis male and comfortable in my own skin that way. But I just like the way long hair and a close facial shave looks on me.
