- 3rd century BC
The 3rd century BC started the first day of 300 BC and ended the last day of 201 BC. It is considered part of the Classical
era, epoch, or historical period.
The first few decades of this century were characterized by a balance of power between the Greek
Hellenistickingdoms in the east, and the great mercantile power of Carthagein the west. This balance was shattered when conflict arose between Carthageand the Roman Republic. In the following decades, the Carthaginian Empirewas first humbled and then destroyed by the Romans in the first and second Punicwars. Following the Second Punic War, Rome became the most important power in the western Mediterranean.
