Æ33 - Marcus Aurelius ΛΑΟΔΙΚΕΩΝ ΠΕΡΓΑΜΗΝΩΝ ΟΜΟΝΟΙΑ

The ΟΜΟΝΟΙΑ ("homonoia") coinage of the Greek East formalized diplomatic friendship between cities — a practice that was partly ceremonial and partly practical, since allied poleis could negotiate shared market access, festival rights, and legal standing for their respective citizens. The pairing of Laodicea ad Lycum with Pergamon was not arbitrary: Pergamon's prestige as the former Attalid capital and seat of the provincial koinon made it a desirable alliance partner, and Laodicea used such issues to punch above its regional weight.

The reign of Marcus Aurelius saw a notable surge in homonoia issues across the conventus system, likely connected to the administrative pressures of the Parthian War and subsequent plague years, which put civic institutions under unusual strain.
