Final answer:
The decline of the Byzantine Empire was caused by Justinian's death, invading forces and internal problems, and Constantine XI. The combination of invading forces and internal problems had the most significant impact.
Step-by-step explanation:
The biggest causes of the decline of the Byzantine Empire were:
- Justinian's death: After the death of Emperor Justinian, the empire faced political instability as his successors were unable to maintain the same level of control and leadership.
- Invading forces and internal problems: The Byzantine Empire faced constant threats from external invaders, such as the Ottoman Turks, as well as internal problems like corruption and economic decline.
- Constantine XI: Emperor Constantine XI died while fighting against the invading Turkish forces, which marked the end of the Byzantine Empire and led to its ultimate decline.
