From the 280's to 400's, what is happening?

• A. The slow collapse of Rome
• B. The rise of a unified Western empire
• C. The unification of China under a single dynasty
• D. The discovery of the Americas

Answer: (A)

This question asks you to think about what happened to Rome as the empire faced growing pressures from borders, economy, and administration from the 280s through the 400s. In the late 3rd century, Diocletian tried to stabilize a sprawling empire by restructuring rule with the Tetrarchy, sharing power to better defend frontiers and manage taxation. Yet these reforms also stretched authority and made unified control more complex rather than simply stronger. Constantine further shifted political weight toward the eastern half by moving the capital to Constantinople and endorsing Christianity, which gradually realigned power toward the East. After Theodosius I, the empire effectively splits into separate East and West, with the West increasingly unable to defend its frontiers and maintain coherence as Germanic groups press inward and internal strains mount. By the end of the 4th century, the West has lost much of its earlier unity and strength, while the East continues in a more durable form, leading to a long, gradual decline rather than a clean rise or quick transformation. So the period is best described as the slow collapse of Rome. The other options don’t fit: a unified Western empire doesn’t take hold in this era, China’s unification under a single dynasty is a separate geographic focus and timeline, and the Americas aren’t discovered by Europeans until centuries later.
