Ruubids

Ruubids refers to a medieval dynastic house that ruled the eastern heartland of the Serenthian kingdom, controlling the Zayir Basin from the late 10th century until the mid-14th century. The name is traditionally traced to Ruub al-Din, a legendary founder or eponym. The dynasty established a hereditary monarchy and a centralized administration, anchored by a network of provincial governors and a standing military.

During their rule, the Ruubids oversaw agricultural development and the growth of towns along important trade routes. They minted coins and invested in public works, including fortifications, bridges, and water systems. The court patronized poets, jurists, and engineers, contributing to a distinctive Serenthian architectural style and a more centralized legal framework. Trade networks across the Serenthian plain and neighboring regions flourished under Ruubid policy.

Notable rulers include Ruub I, who consolidated the dynasty; Ruub II, who expanded frontiers and fortified border towns; and Ruub III, who promoted urban development and administrative reform. The dynasty faced increasing pressure from rival regional powers and experienced internal succession disputes in the 13th century.

Decline and legacy: From the 1240s onward, external invasions and internal fragmentation weakened the Ruubid state, and the line effectively ended by the mid-14th century with the absorption of remaining territories by neighboring realms. The Ruubids left a lasting cultural imprint through monuments, coinage, and administrative practices, shaping later Serenthian governance and regional identity. Modern scholarship treats the Ruubids as central to understanding state formation in the Serenthian world.
