Doclea

Doclea or Dioclea, also known as Diokleia or Diocleia (Montenegrin: Дукља / Duklja; Greek: Διοκλεία, romanized: Diokleía), was an ancient Illyrian, Roman and Byzantine city, in the region of the Docleatae tribe (Roman province of Dalmatia, later Praevalitana), now an archeological site near Podgorica in modern Montenegro. It was an episcopal see from the late Roman period through the Early Middle Ages. Today, it is a titular see, both in the Eastern Orthodox Church, and in the Catholic Church (Latin Rite). When spelled as Diocleia or Diokleia, it should not be confused with ancient Phrygian city of Diokleia in Phrygia (Greek: Διόκλεια Φρυγίας).
