Both the Roman Empire under Trajan and the Byzantine Empire under Justinian I were motivated by a desire to expand their territories and increase their power and influence. However, Trajan's motives were primarily driven by military conquest and the desire to unite the entire Mediterranean region under Roman rule. In contrast, Justinian's motivations stemmed from his ambition to restore the grandeur of the Roman Empire and reunite the territories that had been lost to invasions and rebellions. Both empires ultimately sought to expand and solidify their control over vast territories, but their specific motivations and goals differed to a certain extent.

The motivations for territorial expansion between the Roman Empire under Trajan and the Byzantine Empire under Justinian I were quite similar. Both empires sought to expand their territories for several reasons. They desired to establish dominance and control over neighboring lands, secure valuable resources, extend their influence and power, and protect their borders from external threats. Additionally, both emperors aimed to leave a lasting legacy and perpetuate their dynasties through territorial expansion.

To compare the motivations for territorial expansion between the Roman Empire under Trajan and the Byzantine Empire under Justinian I, we need to analyze historical context and primary sources. Firstly, Trajan's expansion was driven by a desire for military glory and securing the borders of the empire. This can be found in Trajan's own writings and propaganda, such as the famous Trajan's Column. On the other hand, Justinian I's motivations were multifaceted, including religious conversion, reconquering former territories, and restoring the glory of the Roman Empire. Sources like Procopius' "Wars" provide insights into Justinian's intentions. By examining these sources and considering the broader historical context, we can better understand the motivations for territorial expansion in both empires.
