How did the result of foreign invasions differ between the two halves of the empire?

The Eastern Roman Empire, also known as the Byzantine Empire, was able to withstand foreign invasions more successfully than the Western Roman Empire. This was due to the Eastern Empire's more centralized government, its strategic location, and its strong military. The Eastern Empire was also able to benefit from its close ties to the Orthodox Church, which provided a unifying force for the people of the region. In contrast, the Western Roman Empire was more decentralized and lacked the same level of military strength. As a result, it was more vulnerable to foreign invasions, and eventually fell to the Germanic tribes in 476 CE.
