Naturally there were political parties in antiquity

Ancient Rome (133 BC-27 BC):

The Plebeians, then also known as the Democrats, advocated the provision of free bread, the expansion of citizenship rights, the distribution of land to meritorious soldiers, and were strongly in favor of statutory law. In today's terms, the Civilians belonged to the left wing. Representative figures include the Gracchus brothers and Julius Caesar.

The Aristocrats, also known as the Conservatives at that time, opposed the written law, the expansion of citizenship and land reform, and favored the maintenance of the social order of the past, opposing radical reforms. In present-day terms, the aristocrats belonged to the right wing. Representative figures include Sulla and Pompey.

Democrats and aristocrats in ancient Rome and Greece each had their own policy ideas and voter bases; therefore, they were quite progressive. The so-called "party struggle" in the East was just a struggle for power and profit, with no specific policy ideas or progressive nature.
