Year 193 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Merula and Thermus (or, less frequently, year 561 Ab urbe condita). The denomination 193 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 a year.
Flamininus is sent to negotiate with Antiochus III and warns him not to interfere with the Greek states. Antiochus does not accept that Flamininus has the authority to speak for the Greeks and only promises to leave Greece alone only if the Romans do the same.
Flamininus attempts to rally the Greeks against Antiochus III and to counter the pro-Seleucid policy of the Aetolians. When the Aetolians call on Antiochus III for aid, Flamininus persuades the Achaean League to declare war on both parties. He also prevents Philopoemen from taking Sparta.
In the mean time, the Spartan ruler, Nabis, moves to recover lost territory, including Gythium.
