Internal political strife in the Roman Empire weakened the centralized power and authority of the government, making it difficult for leaders to effectively govern and make decisions regarding the defense of the empire. This division among political factions and leaders also hindered the ability to coordinate and mobilize military forces to defend against external threats. The focus on internal power struggles and conflicts diverted resources and attention away from external defense, leaving vulnerabilities and making it easier for enemies to attack and conquer Roman territories.
