Final answer:
Roman expansion had benefits such as increased revenue and trade, but also had costs like loss of life and strained military resources.
Step-by-step explanation:
Roman expansion during ancient times had both benefits and costs. Three benefits of Roman expansion include increased revenue for the empire, control of natural resources, and intercultural connections. Roman conquests allowed the empire to collect taxes and stabilize the economy. They also gained access to valuable resources and expanded trade networks. Furthermore, Roman expansion facilitated connections and interactions between different regions and civilizations.
On the other hand, there were several costs associated with Roman expansion. Continuous conflict resulted in the loss of life and property, which burdened many individuals. Wars also disrupted regional markets, leading to famine and social unrest. Additionally, the expanding frontier and the need to maintain a large military were expensive and strained the Roman military.
