Varangian Guard

The Varangian Guard (Greek: Τάγμα τῶν Βαράγγων, romanized: Tágma tōn Varángōn) was an elite unit of the Byzantine army from the tenth to the fourteenth century who served as personal bodyguards to the Byzantine emperors. The Varangian Guard was known for being primarily composed of recruits from Northern Europe, including mainly Norsemen from Scandinavia but also Anglo-Saxons from England. The recruitment of distant foreigners from outside Byzantium to serve as the emperor's personal guard was pursued as a deliberate policy, as they lacked local political loyalties and could be counted upon to suppress revolts by disloyal Byzantine factions.

The Rus' provided the earliest members of the Varangian Guard. They were in Byzantine service from as early as 874. The Guard was first formally constituted under Emperor Basil II in 988, following the Christianization of Kievan Rus' by Vladimir I of Kiev. Vladimir, who had recently taken control of Kiev with an army of Varangian warriors, sent 6,000 men to Basil as part of a military assistance agreement. Basil's distrust of the native Byzantine guardsmen, whose loyalties often shifted with fatal consequences, as well as the proven loyalty of the Varangians, many of whom had previously served in Byzantium, led the Emperor to employ them as his personal guardsmen.

Immigrants from Scandinavia (predominantly immigrants from Sweden, but also elements from Denmark and Norway) kept an almost entirely Norse cast to the organization until the late 11th century. During these years, Swedish men left to enlist in the Byzantine Varangian Guard in such numbers that a medieval Swedish law, Västgötalagen, from Västergötland declared no one could inherit while staying in "Greece"—then the Scandinavian term for the Byzantine Empire—to stop the emigration, especially as two other European courts simultaneously also recruited Scandinavians: Kievan Rus' c. 980–1060 and London 1013–1051 (the Þingalið).

Composed primarily of Norsemen and Rus' for the first 100 years, the Guard began to see increased numbers of Anglo-Saxons after the Norman conquest of England. By the time of the Emperor Alexios Komnenos in the late 11th century, the Varangian Guard was largely recruited from Anglo-Saxons and "others who had suffered at the hands of the Vikings and their cousins the Normans".^{[This quote needs a citation]} The Anglo-Saxons and other Germanic peoples shared with the Vikings a tradition of faithful (to death if necessary) oath-bound service, and the Norman invasion of England resulted in many fighting men who had lost their lands and former masters and were looking for positions elsewhere.

The Varangian Guard not only provided security for the Byzantine emperors, but also participated in many wars, often playing a decisive role, since they were usually deployed at critical moments of a battle. By the late 13th century, Varangians were mostly ethnically assimilated by the Byzantine Greeks, though the Guard remained in existence until at least mid-14th century. In 1400, there were still some people identifying themselves as "Varangians" in Constantinople.

The earliest members of the Varangian Guard came from Kievan Rus'. A treaty between Rus' and the Byzantine empire under Basil I was agreed in 874 after a period of hostilities. A clause in the treaty obliged Rus' to provide men for Byzantine service. Renewed hostilities between 907 and 911 ended with a new treaty under which any Rus' who chose could serve Byzantium as a right.

The scholarly consensus is that the Rus' people originated in what is currently coastal eastern Sweden around the eighth century and that their name has the same origin as Roslagen in Sweden (with the older name being Roden). According to the prevalent theory, the name Rus', like the Proto-Finnic name for Sweden (*Roocci), is derived from an Old Norse term for "the men who row" (rods-) as rowing was the main method of navigating the rivers of Eastern Europe.

As early as 911, Varangians are mentioned as fighting as mercenaries for the Byzantines. About 700 Varangians served along with Dalmatians as marines in Byzantine naval expeditions against the Emirate of Crete in 902 and a force of 629 returned to Crete under Constantine Porphyrogenitus in 949. A unit of 415 Varangians was involved in the Italian expedition of 936. It is also recorded that there were Varangian contingents among the forces that fought the Arabs in Syria in 955. During this period, the Varangian mercenaries were included in the Great Companions (Gk. Μεγάλη Εταιρεία).
