The prohibition of wearing long hair in late antique Rome may have had little to do with removing foreigners from the city. Instead, a new study suggests Emperor Honorius introduced the ban because many Romans had started copying the hairstyles and clothing of Germanic peoples.
Researchers argue the law reflected growing concern that foreign fashions were changing Roman identity during a period of political instability.
The study, led by Javier Arce, reexamines a law issued on Dec. 12, AD 416, by Emperors Honorius and Theodosius II. The decree ordered that no one could wear long hair inside Rome or its surrounding areas. It also banned clothing made from animal skins and imposed penalties on both free people and enslaved individuals who ignored the rules.
For years, historians have often viewed the law as an attempt to control the growing number of “barbarians” in the city. Arce offers a different explanation. He argues the measure was aimed mainly at Romans who had begun adopting foreign styles rather than at foreigners themselves.
A law that went beyond hairstyles
The research places the decree within a wider effort by Roman emperors to regulate public appearance. Roman authorities had long believed clothing and hairstyles reflected social order, citizenship and political authority.
Earlier emperors had already passed laws telling citizens what they could wear in public. Augustus encouraged Romans to wear the traditional toga instead of cloaks. Later emperors regulated military garments, trousers, boots and even the types of vehicles that senators could use.
According to the study, Honorius’ decree followed this long tradition. The ban on long hair appeared alongside restrictions on animal-skin clothing, suggesting officials wanted to preserve a distinctly Roman appearance.
Researchers say these measures were designed to make social rank easy to recognize while reinforcing public order in the capital.
Long hair symbolized foreign identity
Roman men traditionally wore their hair short. While beards sometimes marked mourning or philosophical life, long hair rarely appeared in Roman portraits. Instead, ancient artwork often showed long hair as a feature of peoples living beyond Rome’s frontiers, including Goths, Franks and other Germanic groups.
Why did Emperor Honorius ban long hair in Rome in AD 416?

Ancient writers also linked long hair with foreign communities. However, the study notes that not every Germanic person wore long hair. Historical sources suggest only kings and members of the highest nobility among groups such as the Franks and Goths were allowed to keep their hair long.
Long hair represented more than ethnicity. It also symbolized rank, authority and royal status. Researchers say this makes it unlikely that large numbers of long-haired Germanic nobles were walking through Rome’s streets. Instead, they argue many ordinary Romans had begun copying elite foreign styles.
Romans may have embraced Germanic fashions
The study points to evidence that Romans had borrowed foreign fashions before. The poet Martial wrote that some Romans dyed their hair red to imitate Germanic tribes centuries earlier.
Arce argues something similar happened during the early fifth century. After decades of contact with Germanic peoples, Roman citizens increasingly adopted their hairstyles and clothing. The timing may also have mattered. Rome had been shaken by Alaric’s sack of the city in AD 410. Germanic influence was becoming more visible across the Western Roman Empire.
According to the study, imperial authorities likely saw these fashion trends as a threat to Roman traditions and social identity. The decree therefore sought to stop what researchers describe as the growing “Germanization” of Roman appearance.
Political fears extended beyond fashion
The study also connects the law with the writings of Synesius of Cyrene, a philosopher and later bishop who lived around the same period. In his work “Eulogy of Baldness,” Synesius praised baldness while mocking men with long hair. He portrayed long-haired men as vain and unreliable, while presenting baldness as a sign of wisdom and moderation.
In another work, “De Regno,” written for Emperor Arcadius, Synesius strongly criticized the influence of Goths within the Roman government and military. He argued that foreign officials should lose positions of power and that Rome should depend more heavily on its own citizens. Researchers believe these writings reflect the same anti-foreign attitudes that shaped Honorius’ law.
The study concludes that the AD 416 decree was not simply a rule about hairstyles. It formed part of a broader campaign to defend traditional Roman identity during a time of major political and cultural change. By banning long hair and animal-skin clothing, imperial authorities attempted to preserve clear social distinctions and resist foreign influences that many Romans believed threatened the empire’s identity.
