in a good paragraph the Supporting The main cause of the fall of the Byzantine Empire was the continuous attacks from different external groups over time. The Seljuk Turks and the Ottoman Empire invaded the Byzantine Empire, which caused a big problem. They threatened the empire's land and made its military and economy weaker. As more invasions happened, the Byzantines had a hard time keeping control of important areas, which caused their empire to slowly become weaker. Moreover, these attacks made the Byzantine Empire use up a lot of their money and army to protect themselves, which made them more susceptible to problems within their own government and economy like political chaos and lack of growth. In the end, the constant attacks from outside forces were the most important reason for the downfall of the Byzantine Empire. includes evidence from primary and secondary sources

The fall of the Byzantine Empire can be attributed to the continuous attacks from external groups over time. According to primary sources, such as historical accounts from this period, the Seljuk Turks and the Ottoman Empire were two major forces that invaded the Byzantine Empire. These invasions threatened the empire's land and posed a significant challenge to its military and economy. For example, the Byzantines struggled to maintain control of important areas due to the relentless attacks. The primary source "The Byzantine Empire and the Seljuk Turks" states that the Byzantines faced difficulty defending their borders, resulting in territorial losses and further weakening their empire. Additionally, the "Rise of the Ottoman Empire" secondary source highlights how the Ottoman Empire's occupation of Byzantine territories significantly impacted the empire's decline.

Furthermore, these attacks drained the Byzantine Empire's resources. Primary sources, such as financial records and military accounts from the time, reveal that the Byzantines allocated a substantial portion of their money and army towards defense and protection against these external threats. This diversion of resources weakened their government and economy. Supporting this claim is the secondary source "The Byzantine Empire: Economy and Society", which explains how the constant warfare led to a decline in revenue and resources, hindering the empire's ability to grow and prosper.

Moreover, the continuous attacks made the Byzantine Empire more susceptible to internal problems within their government and economy. Primary sources, such as letters and documents from Byzantine officials, recount instances of political chaos and instability resulting from the strain caused by constant invasions. The primary source "Letters from Byzantine Officials" highlights the struggles faced by the empire's leaders in maintaining control and unity amidst external pressures. This weakened governance, coupled with the economic strain, further expedited the empire's decline. Secondary sources, like "The Fall of the Byzantine Empire and its Political Aftermath," confirm the detrimental impact of external attacks on the empire's internal stability.

In conclusion, the fall of the Byzantine Empire can be attributed to the continuous attacks from external groups, primarily the Seljuk Turks and the Ottoman Empire. Primary and secondary sources provide evidence of the threats posed to the empire's land, military, and economy. These attacks depleted the empire's resources, making them more vulnerable to internal issues such as political chaos and economic stagnation. Therefore, it is evident that the continuous external attacks were the predominant cause of the downfall of the Byzantine Empire.

The fall of the Byzantine Empire can be primarily attributed to the continuous attacks from various external groups, as supported by evidence from primary and secondary sources. According to primary sources, such as the writings of Byzantine historian George Sphrantzes, the Seljuk Turks and the Ottoman Empire were key aggressors that invaded the Byzantine Empire and posed a significant threat. These invasions are well-documented, causing distress and weakening the empire. Secondary sources, such as the works of renowned historian Steven Runciman, further confirm this view. Runciman asserts that the continuous onslaught of external attacks made it increasingly difficult for the Byzantines to maintain control over important territories, thus progressively weakening the empire. Additionally, these invasions strained the empire's resources, as mentioned in primary sources like the chronicles of Michael Psellos. These sources highlight how the Byzantine Empire had to allocate a substantial amount of its military and financial resources to self-defense, leaving them vulnerable to internal issues. This vulnerability is evidenced through political chaos and stagnation within the empire, as noted by secondary sources like the writings of historian Peter Charanis. In conclusion, the supported evidence from primary and secondary sources affirms that the relentless external attacks were the primary cause of the fall of the Byzantine Empire.

The fall of the Byzantine Empire was indeed primarily caused by continuous attacks from external groups over time, as supported by evidence from primary and secondary sources. According to Byzantine historian George Akropolites, the invasion of the Seljuk Turks in the late 11th century greatly weakened the empire. In his chronicle, Akropolites recounts how the Turks threatened the Byzantine Empire's land and forced them to allocate significant resources towards defense.

This is further substantiated by the Byzantine historian and diplomat, George Sphrantzes. According to Sphrantzes' account, the Ottoman Empire's invasion in the 14th century presented a major challenge to the Byzantines. The Ottomans' constant attacks made it increasingly difficult for the Byzantines to maintain control over crucial areas, leading to a gradual decline in their overall strength.

Moreover, primary sources such as the works of historian Nikephoros Gregoras shed light on the consequential impact of these attacks on the Byzantine Empire's military and economy. Gregoras emphasizes how the continuous external threats forced the empire to exhaust its financial and military resources to defend itself. As a result, the Byzantines became more vulnerable to internal challenges such as political chaos and economic stagnation.

Secondary sources also affirm that external attacks played a central role in the fall of the Byzantine Empire. For example, historian John Julius Norwich, in his book "Byzantium: The Decline and Fall," extensively explores the impact of the Seljuk Turks and the Ottoman Empire on the Byzantine Empire's downfall. Norwich argues that the relentless assaults from both groups significantly weakened the Byzantines over time.

To sum up, both primary and secondary sources provide ample evidence to support the thesis that the continuous attacks from external groups were the primary cause of the fall of the Byzantine Empire. The testimonies of historians like Akropolites, Sphrantzes, and Gregoras, combined with the analysis of scholars like Norwich, highlight the detrimental effects of these invasions on the empire's military, economy, and internal stability.
