The empire known for its use of a vast network of roads to connect its territories was the Roman Empire. At its height, the Roman Empire extended across Europe, North Africa, and parts of Asia, creating a complex web of roads that facilitated trade, military movement, and communication. Constructed primarily for military purposes, these roads also enabled the efficient travel of civilians and goods, helping to integrate the diverse regions under Roman control. The saying "All roads lead to Rome" emphasizes the centrality of this network to the empire's cohesion and economic prosperity, leaving a lasting legacy on infrastructure development throughout history.
