The Hunnic invasion and conquest of what is now Romania took place in the 4th and 5th centuries. Led by powerful leaders like Attila, the Huns emerged from the eastern steppes, sweeping across Europe and reaching the region of present-day Romania. Known for their fearsome cavalry and aggressive tactics, the Huns overran various Germanic tribes and other local populations, establishing control over parts of the territory.

Their presence in the region played a role in shaping the subsequent history of Romania and its neighboring areas. The Hunnic rule was transient, and their empire began to fragment after Attila's death in 453 CE. Despite their relatively brief dominance, the Huns had a lasting impact on the region, contributing to the migratory movements and cultural shifts that shaped the early medieval period in Eastern Europe. Their invasion also led to increased pressure on the Roman Empire's borders, contributing to its eventual decline.
