Thomas III d'Autremencourt, Lord of Salona, Marshal of Achaea

Thomas III d'Autremencourt, also recognized as de Stromoncourt, was a prominent noble in early 14th-century Central Greece, serving as the fourth and final Lord of Salona, a territory now known as Amfissa. His rule over this significant domain began in 1294, guiding his lands through a period of considerable political and martial upheaval.

A Dual Role and a Fateful End

Beyond his responsibilities as Lord of Salona, Thomas III held another crucial position: marshal of the Principality of Achaea. This role solidified his standing within the broader Frankish states that then dotted the Greek landscape. However, his life, and with it, the direct lineage of his family's rule over Salona, met a definitive end on March 15, 1311. This fateful day saw him perish in the devastating Battle of the Cephissus, a brutal confrontation against the formidable Catalan Company.

The Aftermath: A New Era for Salona

The Battle of the Cephissus proved to be a watershed moment, dramatically reshaping the power structures of the region. Following Thomas III's death, his widow and the entirety of his domain, Salona, transitioned into the control of Roger Deslaur. Deslaur himself emerged as a key figure in the immediate aftermath, briefly assuming leadership of the victorious Catalan Company from 1311 to 1312. This transfer of power not only concluded the d'Autremencourt family's reign but also heralded a new chapter for the lands and people of Salona under different authority.
