Year 211 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Maximus and Maximus (or, less frequently, year 543 Ab urbe condita). The denomination 211 BC for this year has been used since the early medieval period, when the Anno Dominicalendar era became the prevalent method in Europe for naming years.
Hannibal marches northwards on the city of Rome in a belated and unsuccessful effort to capture the city.
Rome faces the burdens of inflation and the danger of famine, caused by the disturbed conditions in Italy and Sicily and the withdrawal of so many men from farming. The situation is only relieved by an urgent appeal by the Romans to the King of Egypt, Ptolemy IV, from whom grain is purchased at three times the usual price.
The Roman commander Marcus Valerius Laevinus explores the possibility of an alliance with the Aetolian League as the Aetolians are once again ready to consider taking up arms against their traditional enemy, Macedonia. A treaty is signed to counter Philip V of Macedon who is allied to Hannibal. Under the treaty, the Aetolians are to conduct operations on land, the Romans at sea. Also, Rome will keep any slaves and other booty taken and Aetolia will receive control of any territory acquired.
