Counts of Brehna

The Brehna line of the Wettins holds the old county round Brehna between the Mulde and the Saale, where a castle stood before 1053 and a house of Augustinian canonesses (Kloster Brehna) is the family's burial church, and further east the lands on the Black Elster round Herzberg, Schlieben and Löben, where the brothers moved their main seat after 1181.

The two brothers back Philip.

Overlord

The king

  • Zörbig and the villages between Brehna and the Mulde (not pinned)

How it was acquired

From their father Frederick I, who received Brehna in Conrad the Great's division of 1156.

Allies and rivals

The Wettin cousins; the Ascanians at Wittenberg to the north.

How things stand that morning

Hold Brehna and the Herzberg lands; the de.wikipedia account puts them on Philip's side in the throne war.

Wealth

Farmland round Brehna; forest and marsh on the Black Elster.

Military

Castles at Brehna, Herzberg and Schlieben. No numbers.

Threats

  • Ascanian expansion from Wittenberg

Places of note

  • Brehna: Castle and family nunnery
  • Herzberg: Main seat after 1181

Where the sources disagree

  • The Brehna article also lists Camburg among the family's seats; we draw Camburg with the margrave of Meissen (see Margrave Dietrich).

Evidence: One article; the brothers' joint rule and dates are clear, their lands round 1200 less so.

On the map: Schematic.
