Grain for a Giant City
1By the first century BCE, Rome was one of the largest cities in the world. Historians estimate it held close to a million people by about the year 1 CE. Farms near the city could not grow enough wheat for so many people. Most of Rome's wheat came by ship from Sicily, North Africa and, after 30 BCE, Egypt. When storms, wars or poor harvests cut the supply, the price of grain in Rome shot up.
2In 123 BCE, the tribune Gaius Gracchus passed a law that let citizens in Rome buy a monthly ration of wheat at a low price set by the state. The state bought the grain and sold it for less than it cost, so the treasury paid the difference. In 58 BCE, a leader named Clodius made the monthly ration free. Each man on the grain list received about 5 modii of wheat a month, roughly 33 kilograms.
3The list grew long. In 46 BCE, Julius Caesar ordered a count and cut the list from 320,000 to 150,000 men. Under Emperor Augustus, the number was a little more than 200,000. Only adult male citizens living in Rome were on the list, though their grain fed whole families. Enslaved people and foreigners received none.
4Leaders also worked to keep the ships coming. In 22 BCE, during a serious shortage, Augustus took personal charge of the grain supply. In 42 CE, Emperor Claudius began building a large new harbor near Ostia, at the mouth of the Tiber River, so big grain ships could unload safely. He also promised shipowners that the government would pay for their losses if storms sank their ships, so that they would keep sailing in winter, when storms were common.
