Final answer:
After conquest, Rome focused on assimilating territories by granting citizenship, creating infrastructure, extracting economic benefits, and strategically securing the regions to prevent rebellion.
Step-by-step explanation:
Rome's first priority after conquering a place was to secure loyalty and military support by offering citizenship, albeit without voting rights, and integrating the conquered people into Roman society. This was achieved through infrastructure development, such as building roads, aqueducts, and cities with a grid system.
Additionally, Rome sought economic benefits through resource control and wealth extraction, mainly via taxation. To ensure ongoing control and assimilation of newly conquered territories, the Romans also employed strategies like establishing colonies as defensive outposts, dividing and conquering to prevent united opposition, and building networks of well-constructed roads to spread the influence of Roman language and culture.
