Dobrolak
Dobrolak is the earlier recorded name of the settlement at that time called Cherven Bryag, in northern Bulgaria. It lies on the right bank of the Iskar River near Pleven. Ottoman registers mention Dobrolak in 1431. During the sixteenth century the place appears as Cherven Bryag within the Ottoman region of Nikopol. The newer name means "red shore" and refers to the reddish clay found near the river.
This change of name records continuity of settlement alongside a change in the vocabulary by which local administrators identified it. The Iskar connected the community with a wider river landscape and gave it access to water, fertile ground and movement through northern Bulgaria. Its older rural life belonged to a district of villages and estates under Ottoman provincial administration.
Dobrolak's history therefore combines a medieval river settlement with Ottoman administrative naming.
