Historians believe that the city was founded in 753 BCE.
Written records were not kept, so little is known about the founding of Rome.
A wall found in the Roman Forum may date back to 900 BCE.
Explanation:
The founding of Rome and the most ancient history of the city today are only sparsely known from other than mythological material of later periods. The oldest archaeological finds in the area date from the 10th century BC. The city has probably grown up as a result of a tribal union between the Latino population that inhabited the Tiber Valley and Lazio. According to Livius, Rome was first founded on April 21, 753 BC by first king Romulus, but these accounts are considered much later legendary tales. The oldest houses found on the Palatine Hill date from around 900 BC and were replaced by new and larger ones in the 8th century BC. The myth of Romulus is neither contradicted nor confirmed by the archaeological finds.
