Which part of the empire suffered the most invasion?

The western part of the Roman Empire suffered the most from invasions, particularly during the 4th and 5th centuries AD. This region faced repeated attacks from various Germanic tribes, including the Visigoths, Vandals, and Ostrogoths, as well as incursions from the Huns. The culmination of these invasions contributed significantly to the decline and eventual fall of the Western Roman Empire in 476 AD. In contrast, the Eastern Roman Empire, or Byzantine Empire, managed to withstand invasions more effectively, preserving its territory and influence for centuries longer.
