Final answer:
Political instability was a significant factor in the fall of the Roman Empire. Document A shows the rapid turnover of emperors, while Document C highlights the interference of the Praetorian Guard in imperial succession. These instances of instability undermined the Empire's cohesion and left it vulnerable to external threats.
Step-by-step explanation:
Political instability played a significant role in the fall of the Roman Empire. Document A from the DBQ Project states that rulers changed quickly, which led to a lack of stability and effective governance. For example, in one year, the Roman Empire had six different emperors. This constant turnover at the top created a power vacuum and weakened the Empire's ability to defend itself against external threats.
Moreover, Document C highlights the political instability caused by the Praetorian Guard's interference in imperial succession. The assassination of Emperor Pertinax and the auctioning off of the throne to the highest bidder further exemplify the lack of stability and the erosion of orderly government in Rome.
These instances of political instability ultimately contributed to the fall of the Roman Empire by undermining its internal cohesion, weakening its governance, and leaving it vulnerable to external threats. The Empire's inability to maintain stable leadership and effective governance weakened its economy, military, and overall societal structure, ultimately precipitating its downfall.
