For the most part, the successors to Augustus continued his administrative policies and building program, though with less innovation and more ostentation. Claudius began a great port near Ostia, at the mouth of the Tiber, to facilitate grain shipments directly to Rome. Commerce remained largely in private hands, with public officials acting to ensure a regular supply and to prevent speculation.

Nero can be credited with introducing the most up-to-date ideas on town planning, though at a terrible price. The great fire of ad 64 destroyed large sections of the city. In the devastated areas Nero built new streets and colonnades as well as his fabulous Golden House, and he encouraged private citizens to build more spacious and more fireproof houses and apartment buildings with better access to the public water supply. Although Nero made Rome a more pleasant city in which to live, his measures did not prevent other devastating fires such as the one in 191 that gave Septimius Severus the opportunity to rebuild the city.

Other emperors in the late 1st and early 2nd centuries added to the glory of the imperial house and the amenities of Roman life—grandiose imperial forums, temples, arches, baths, and stadiums. Trajan’s Forum, with its complex of buildings and courtyards, and his market, with its tiers of shops and its great market hall, represent, in the judgment of many historians, the supreme achievement of city planning in Rome. Trajan’s Column, which narrates his victories beyond the Danube, was recognized as without peer even in the Christian Middle Ages. Hadrian left two enduring structures in Rome: the great domed Pantheon and his mausoleum, which in ad 590 was renamed Castel Sant’Angelo.

In the late 1st and early 2nd centuries Rome was at the peak of its grandeur and population, which has been estimated at more than 1,000,000 persons but was probably less. It was kept at a high level by a steady stream of immigrants, both slave and free, from the provinces and beyond—although life expectancy in the city was probably lower than elsewhere in the empire. Rome’s famous paved streets, water supply, and sewage system, however, should not be overestimated; even after the reforms of Nero, large numbers of the urban inhabitants continued to live in expensive, poorly built, overcrowded, and unheated slums without water or cooking facilities. The arena and the public bath relieved some pressures of high density and physical squalor, but Rome’s refined technology was applied haphazardly to the problems of urban social organization. Garbage was usually dumped into the Tiber or pits on the city’s outskirts.

Rome was a city of consumers, both rich and poor, and never a great industrial or commercial centre. The small shop was the basic unit of production and distribution through the imperial period, and the numerous trade associations served social and religious functions until they were enveloped in the economic regimentation of the late empire. Although Rome far surpassed any other ancient city in size and monumental splendour, its minimal economic and social achievement augured ill for the future.
