The Goths who crossed into Roman territory in the 370s came not as unified invaders but as desperate refugees fleeing Hunnic pressure. Roman authorities settled them as foederati - armed allies who defended borders in exchange for land and supplies. This arrangement defined Gothic existence for generations. They lived among Romans, served in Roman armies, adopted Roman administrative practices, yet maintained distinct identity through language and Arian Christianity. A Goth might command Roman legions, speak Latin fluently, and live in a Roman villa - while stubbornly refusing to convert to Catholic Christianity. Gothic communities spread across the empire wherever military service took them, from the Rhine to the Danube, from Gaul to North Africa. They didn't conquer territory so much as gradually occupy it, settling in clusters that quickly expanded as more families joined successful settlements.
The collapse of Roman authority in the West transformed Gothic communities into kingdoms. Visigoths established themselves in southwestern Gaul and Hispania. Ostrogoths seized Italy under Theodoric, ruling from Ravenna while maintaining Roman bureaucratic systems. These weren't primitive kingdoms imposed on civilization - Goths governed through existing Roman structures, employed Roman administrators, patronized Latin literature and architecture. But they remained distinct, their Arian faith separating them from Catholic Roman populations. This religious division ultimately weakened both kingdoms. The Ostrogothic kingdom fell to Byzantine reconquest in the 550s after devastating wars that ruined Italy. The Visigothic kingdom survived longer but never fully integrated with Hispanic Romans. When Muslim armies crossed from North Africa in 711, internal divisions helped collapse resistance. Within a decade, the kingdom that had ruled Hispania for three centuries nearly vanished.
Gothic strength lay in their adaptability and military prowess. Generations of Roman military service had made them expert soldiers who understood both Germanic and Mediterranean warfare. They could field effective cavalry and infantry, storm cities or defend fortifications. Their willingness to adopt Roman administrative practices while maintaining Gothic military organization created surprisingly stable hybrid states. Gothic communities showed remarkable ability to incorporate other peoples - defeated enemies, allied tribes, even rebel factions could become Goths if they accepted Gothic leadership. This flexibility helped them spread quickly across new territories. Yet this same adaptability created weaknesses. Religious division with Catholic populations bred resentment and limited cooperation. Gothic identity remained tied to military service and Arian Christianity rather than ethnicity or language, making it fragile when military defeats came. The kingdoms built impressive cultural syntheses - Visigothic law codes, Ostrogothic architecture - but couldn't overcome the fundamental problem of ruling large Catholic populations as an Arian military elite.
