Paristrion (), or Paradounabon/Paradounabis (), which is preferred in official documents, was a Byzantine province covering the southern bank of the Lower Danube (Moesia Inferior) in the 11th and 12th centuries.

Dobrotitsa (, ; or ; in contemporaneous Byzantine documents; Dobrodicie in contemporaneous Genoese documents) was a Bulgarian noble, ruler of the de facto independent Principality of Karvuna and the Kaliakra fortress from 1354 to 1379–1386.

Pereyaslavets (East Slavic: ) or Preslavets () was a trade city located near mouths of the Danube. The city's name is derived from that of the Bulgarian capital of the time, Preslav, and means Little Preslav (). In Greek it was also known as Presthlavitza (). Several theories exist regarding the exact location of the city: either at Preslav or in its vicinity in Bulgaria, or at Isaccea, Nufăru, Murighiol or Jurilovca in Romania.
