Zdeslav of Croatia

Zdeslav (, Sedesclavus) was a duke (knez) in Croatia from 878 until his death in 879. He was from the Trpimirović dynasty.

Biography
Zdeslav was the son of Trpimir I. After his father's death in 864, an uprising was launched by a powerful Croatian nobleman from Knin called Domagoj. Zdeslav was exiled along with his brothers Petar and Muncimir to Constantinople. Domagoj died in 876, and was succeeded by his son. Zdeslav overthrew him in 878 with the help of the Byzantines, expelled Domagoj's sons and restored peace with Venice. He acknowledged the supreme rule of Byzantine Emperor Basil I.

In 879, Pope John VIII asked Duke Zdeslav for an armed escort and protection for his legate who was crossing Croatia on his way to Bulgaria, ruled by Boris I. In early May 879, Zdeslav was killed by arrows near Knin in an uprising led by Branimir, a relative from Domagoj, instigated by Pope John VIII fearing Byzantine power.
