Historical Trajectory
Phase I: Rise
The Genoese Zaccaria family seized the island of Chios in 1304, establishing an autonomous lordship in the eastern Aegean. Although the Zaccaria nominally acknowledged Byzantine suzerainty, they governed the island as an effectively independent domain. At its height, the lordship extended beyond Chios to encompass several nearby islands along the coast of Asia Minor, leveraging Genoese commercial networks and maritime power.
Phase II: Zenith
At its peak, the Lordship of Chios served as a Genoese commercial outpost controlling strategically located islands off the Anatolian coast. The Zaccaria family exploited Chios's position to benefit from lucrative Aegean trade routes. The island's resources, including its famed mastic production, supported the economic base of the lordship and reinforced its value to its Genoese rulers.
Phase III: Decline
The lordship ended in 1329 when Byzantine forces, aided by the local Greek population who rose against Genoese rule, recovered Chios. The revolt reflected deep dissatisfaction among the Greek inhabitants with Zaccaria governance. Although Genoese influence over the island was extinguished at this point, Chios returned to Genoese hands in 1346 under the newly formed Maona of Chios and Phocaea.
