The hill county between the Ruhr and the Sieg, east of the Rhine opposite Cologne, held by the senior line of the Berg house since the division of 1160-1161 that gave the Altena lands to Eberhard.
Its power rests less on land than on advocacies: Deutz (hereditary), Siegburg (since 1138-1139), Gerresheim, St Severin in Cologne, St Cassius in Bonn, and the advocacy at Kaiserswerth, where Engelbert I displaced the Hardenberg family. Count Adolf III, about 25 or older, is the cousin of Archbishop Adolf and fought first for Otto IV; his teenage brother Engelbert is already cathedral provost. On 1 January 1200 Berg is with Otto.

Overlord
The king for the county; the archbishop of Cologne for many fiefs and advocacies; the landgrave of Thuringia for Windeck (a sub-fief from Henry Raspe since 1174).
Allies and rivals
Allies: Archbishop Adolf (cousin), the Altena counts, Otto IV. Rivals: the counts of Hückeswagen, the Sayn counts on the Sieg (Blankenberg) in the longer run, the lords of Hardenberg.
The realm that morning
Adolf III holds Berg and its advocacies and backs Otto IV (welf), medium confidence: he 'first fought for Otto, whom his cousin had raised to king' (de.wikipedia), and his family ties bind him to Adolf of Cologne; no charter pins him that winter.
Wealth
Advocacy dues and courts over the great abbeys (Siegburg, Deutz, Gerresheim, the Cologne and Bonn chapters), the Rhine bank at Düsseldorf and Monheim, the iron and forest of the uplands, the Wupper and Sieg mills. No figures.
Military
Castles: Burg on the Wupper (residence, built by Adolf II), Bensberg, Neu-Windeck on the Sieg, Neuenberg near Lindlar; the old seat Burg Berge was given to the Cistercians of Altenberg in 1133. No figures.
Threats
- Staufen raids across the Rhine (none attested on the right bank in 1198-1199)
- Debts of the war shared with his cousin the archbishop
Family and heirs
No son by 1200; brother Engelbert in holy orders; the marriage to Bertha (probably of Sayn) and the birth of Irmgard are not pinned before 1200.
Officers
- Not pinned by name: the count's ministeriales at Burg, Bensberg, Windeck and Neuenberg.
Where the court is this winter
Not pinned; Burg on the Wupper is the residence.
Treaties and feuds
- Family alliance with the archbishop (cousin) and the Altena lines
- Claims of the counts of Hückeswagen on Berg pledges, not settled until 1260
Rome and the Church
No dispute attested for 1199.
Coinage
The counts struck pennies copying the Cologne coin (Adolf I, Adolf II, Engelbert I); a mint at work in 1200 is not pinned.
The host
Knights and ministeriales of the Bergisch hill castles and the advocacies; no figures.
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- About 1200 (day not pinned)Death of Bruno III of Berg, his uncle (a son of Adolf II, half-brother of his father) and former archbishop, a monk at Altenberg, the family abbey.Depends on: Natural death Stopped by: Nothing in play
- 1200Stays with Otto and his cousin the archbishop; he will follow Adolf to Philip only in 1204.Depends on: Adolf staying with Otto Stopped by: A Staufen offer to the Berg-Altena house
Places of note
- Burg on the Wupper: Residence of the counts
- Altenberg abbey: Family abbey on the site of the old castle of Berge
Where the sources disagree
- The relationship of Bruno III to the Berg counts is given differently by the sources (half-brother of Engelbert I in one, uncle of Archbishop Adolf in another); he was a son of Adolf II.
Evidence: Accession, family and advocacies are well attested; the throne-war stance is general (first for Otto) rather than dated to the winter.
On the map: The count's lands are drawn on the lord record Berg.
