This chapter summarizes the main findings of this book. It reviews how economic activities carried out by Italians contributed to the integration of the Italian peoples into the Roman framework. Throughout the Republican period, Italians had been able to profit from the expansion of the Roman dominion in the Mediterranean; through overseas trade and commercial agriculture they had gained significant wealth, which they invested in the Italian landscape. They were often ahead of Romans when it came to engagement with Hellenistic culture. However, their economic prosperity and cultural sophistication did not lead to civic equality with Roman citizens, nor to equal opportunities to exploit the territories that the Italians had conquered under Rome’s lead. Eventually, the Italians rebelled against Rome in the Social War (91–88 BC), after which they were granted citizenship. The grant of citizenship stimulated further integration, in the economic, political, social, and cultural senses, between Romans and Italians.
