WORLD HISTORY

Detailed explanation-1: -The four main architectural inventions are: concrete, the Roman round arch (not invented by them, but mastered nonetheless), aqueducts, and domes. Concrete is likely one of the most famous and most important, as it led to the ability to create some of their most impressive structures.

Detailed explanation-2: -The Romans were particularly skilled in administration, organization, and engineering. They had a highly trained and disciplined military and an efficient bureaucracy. Without these qualities, the Romans would never have been able to manage their sprawling empire.

Detailed explanation-3: -Roman cities were built around a forum, or center, which contained temples, markets, amphitheaters, and government buildings. These were surrounded by walls and cleverly built aqueducts which supplied water to city reservoirs.

Detailed explanation-4: -Beginning in the eighth century B.C., Ancient Rome grew from a small town on central Italy’s Tiber River into an empire that at its peak encompassed most of continental Europe, Britain, much of western Asia, northern Africa and the Mediterranean islands.
