CE3, or the Common Era 3, refers to a specific period in the Gregorian calendar, which is widely used today. It is part of the larger Common Era system that counts years from the traditional date of the birth of Jesus Christ. CE3 corresponds to the year 3 AD, a time when the Roman Empire was at its height and various cultures were developing across Europe, Asia, and Africa. During CE3, significant historical events and developments were occurring, although detailed records from this time are scarce. The period is characterized by the spread of Hellenistic culture following the conquests of Alexander the Great and the establishment of trade routes that facilitated cultural exchange.
