The Roxolani were a Sarmatian people and are believed to be an offshoot of the Alans. However, according to Strabo, they were the most remote of Scythian peoples.
Name
In his Getica, Jordanes uses a variant name, Rosomoni for the Roxolani. The following tribal names in Bavarian Geographer apparently belong here:
Sebbirozi habent ciuitates XC. Attorozi habent ciuitates XLVIII, populus ferocissimus. Vuillerozi habent ciuitates LXXX. Zabrozi habent ciuitates CCXII. Chozirozi habent ciuitates CCL.
The etymology of Roxolani may combine ruxh or rukhs Alanic "radiant light" + Alani. This would make Roxolani an endonym translatable as "bright Alans". George Vernadsky suggested, along similar lines, that the Rocas, a tribe conquered by the Ostrogoths in the 4th century, may have been synonymous with the Roxolani/Rosomoni. To be specific, Vernadsky suggested that Rocas may have its origins in ruxh and the name of the Asii, a steppe tribe whose name may have been interchangeable with that of the Alans. Other theories suggest that Iranian-speaking steppe peoples, such as the Alans, merged in a variety of forms with early Slavic peoples. According to one hypothesis, the Antes originated as a sub-group of Alans. A similar theory, reported by Vernadsky, suggests that Roxolani originated as a portmanteau of the names of the Slavic regions and the Alani.
In the mid-1st century AD, the Roxolani began incursions across the Danube into Roman territory. One such raid in AD 68/69 was intercepted by the Legio III Gallica with Roman auxiliaries, who destroyed a raiding force of 9,000 Roxolanian cavalry encumbered by baggage. Tacitus describes the weight of the armour worn by the "princes and most distinguished persons" made "it difficult for such as have been overthrown by the charge of the enemy to regain their feet". The long two-handed kontoslance, the primary melee weapon of the Sarmatians, was unusable in these conditions. The Roxolani avenged themselves in AD 92, when they joined the Dacians in destroying the Roman Legio XXI Rapax.
2nd century
During Trajan's Dacian Wars, the Roxolani at first sided with the Dacians, providing them with most of their cavalry strength, but they were defeated in the first campaign of AD 101–102 at Nicopolis ad Istrum. They appear to have stood aside as neutrals during Trajan's final campaign of AD 105–106, which ended in the complete destruction of the Dacian state. The creation of the Roman province of Dacia brought Roman power to the very doorstep of Roxolani territory. The Emperor Hadrian reinforced a series of pre-existing fortifications and built numerous forts along the Danube to contain the Roxolani threat.
Later, Marcus Aurelius who was dead by the 3rd century, also campaigned against the Roxolani along the Danubian frontier. They are known to have attacked the Roman Province of Pannonia in 260; shortly afterwards contingents of Roxolani troops entered Roman military service.
4th century
Like other Sarmatian peoples, the Roxolani were conquered by the Huns in the mid-4th century.
Culture
The Greco-Roman historian Strabo described them as "wagon-dwellers".
