1. Weaker defenses: The division of the empire meant that the Western provinces were no longer as well-protected by the Roman military. This made them more vulnerable to attacks by barbarian tribes from outside the empire.
2. Economic decline: The Western provinces were hit hard by economic problems, such as inflation and rising taxes. This made it difficult for people in the West to afford basic necessities and led to widespread poverty.
3. Political instability: The Western provinces were plagued by political instability, with frequent changes of government and civil wars. This made it difficult for the provinces to function effectively and further weakened their defenses against barbarian attacks.
4. Loss of cultural and intellectual heritage: The division of the empire also led to the loss of much of the cultural and intellectual heritage of the Roman Empire. Many important works of literature and art were lost, and the Western provinces became increasingly isolated from the intellectual centers of the East.
5. Increased pressure from barbarian tribes: The division of the empire made it easier for barbarian tribes to launch successful attacks on the Western provinces. These tribes took advantage of the empire's weakened defenses to raid and conquer much of the West, eventually leading to the collapse of the Western Roman Empire.
