The eastern hemisphere in 200 BC
200 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 Cotta (or, less frequently, year 554 ). The denomination 200 BC for this year has been used since the Ab urbe condita early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Philip V of Macedon's fleet defeat the Rhodians at Lade. His forces then advance into Pergamum, plundering Pergamese territory and attacking cities in Caria. The
Acarnanians, with Macedonian support, invade Attica, causing Athens, which has previously maintained its neutrality, to seek help from the enemies of Philip. Attalus I of Pergamum, who is with his fleet at Aegina, receives an embassy from Athens asking him to come to the city for consultations. After he is told that Roman ambassadors are also in Athens, Attalus goes there in haste. The Roman ambassador to
Greece, Syria, and Egypt, Marcus Aemilius Lepidus delivers an ultimatum to Philip V warning Macedonia not to make war on any Greek state. Philip decides to reject the Roman ultimatum and the Romans declare war on Macedon, thus starting the Second Macedonian War. The Roman consul,
Publius Sulpicius Galba Maximus, asks Attalus I and his fleet to meet up with the Roman fleet off the Greek Aegean coast and they conduct a naval campaign against Philip V, harassing Macedonian possessions in and along the Aegean.
