What were some factors that led to the decline of the Roman Empire?

The decline of the Roman Empire can be largely attributed to military overreach and internal strife, making this the most accurate answer. Military overreach refers to the expansion of the empire to such vast territories that it became increasingly difficult to manage and defend. As Roman armies were stretched thin across distant frontiers, they faced logistical challenges and were often unable to respond effectively to threats. This overextension made the empire vulnerable to invasions by external forces, particularly from various Germanic tribes and others.

Internal strife also played a critical role in the empire's decline. Political instability, corruption, and civil wars weakened the central authority. The empire frequently experienced power struggles, with competing factions vying for control, leading to a distracted and divided government. This internal conflict diminished Rome's ability to effectively deal with external pressures, further exacerbating its vulnerability.

Together, these factors created a precarious situation for the Roman Empire, contributing to its eventual fall. In contrast, the other options do not align with the realities of the Roman decline, as artistic innovations and cultural exchanges typically represent strength, heightened economic prosperity indicates stability rather than decline, and minimal warfare with neighboring tribes doesn't reflect the true military challenges faced during this period.
