Iernut

Iernut, historically known as Radnót, is a town located in Mureș County within the central Transylvania region of Romania. Situated on the Transylvanian Plateau along the banks of the Mureș River, it lies approximately 30 kilometers west of the county seat, Târgu Mureș. While the area has been inhabited since the Middle Bronze Age, evidenced by artifacts from the Wietenberg culture found in nearby villages, the settlement officially gained town status in 1989 following the Romanian rural systematization program. Today, it serves as an administrative hub for eight surrounding villages and sits at a strategic intersection of national roads connecting major cities like Turda, Mediaș, and Bacău.

The town holds profound historical significance, particularly stemming from the 17th century when it was part of the Principality of Transylvania. It is most famous for hosting the signing of the Treaty of Radnot on December 6, 1656, during the Second Northern War, which dictated the partition of the Polish–Lithuanian Commonwealth among its signatories. Due to frequent invasions during this turbulent era, Prince Michael I Apafi convened the Transylvanian Diet at the local fortress in the late 1680s to address regional security. Architecturally, the town is noted for its Reformed Church, whose construction began in 1486, standing as a testament to its medieval heritage within the former Küküllő County.

Following World War I, Iernut became part of Romania after the Union of Transylvania was declared in 1918. Currently, the town functions as a local center for governance and transport, with the partially constructed A3 motorway running just south of its limits. Although the specific fortress mentioned in historical records regarding the Diet is not detailed in terms of current preservation status in the provided text, the town maintains its identity through its historic church and its role in significant European diplomatic history. The community continues to evolve while preserving its legacy as a site where major geopolitical decisions once reshaped Eastern Europe.
