The Plains are the old counts of the country west and north of Salzburg, named after their castle on the hill above Großgmain.
Their power is advocacies: of St Peter's in Salzburg, of their own foundation Höglwörth, of Berchtesgaden (since 1190) and of the Chiemsee houses. In 1167 they burned Salzburg for the emperor; now two young cousins share the house, and one of them is the Bavarian duke's nephew. Since 1187-88 they are also counts of Hardegg in Lower Austria, the other half of their power (written by the Austria researcher).
When the line ends in 1260 most of their Salzburg-country lands, the later Rupertiwinkel, will pass to the archbishop.
Who he is
- Name
- Liutold III (about 1175-1219) and his cousin Konrad I (about 1180-1250), holding together
- Title
- Counts of Plain and of Hardegg, advocates of St Peter's at Salzburg and of Berchtesgaden
- Since
- Liutold after his father Liupold died in 1193 (styled count of Hardegg in 1198, of Plain in 1203); Konrad after his father Henry I died in 1196 and his elder brother Otto I (count of Plain 1196) died in 1197 (Konrad styled count of Plain in 1197, of Hardegg in 1200, day not pinned)
- Born
- Liutold about 1175; Konrad about 1180 (both approximate)
- Family
- Descendants of Werigand, who built the Plainburg about 1100 and founded Höglwörth (1123). Liutold III is the son of Count Liupold (died 1193), who led the Plain men that burned Salzburg for Barbarossa in 1167, and of Ida of Burghausen (alive, died after 1210); his brothers Gebhard and Henry are clerics (later bishop of Passau, 1223, and abbot of Kremsmünster, 1220). Konrad I is the son of Count Henry I (died 1196) and of Agnes of Wittelsbach, sister of Duke Louis I of Bavaria (married 1186 per en.wikipedia; before 1177 per the Plain genealogy), so the duke is his uncle. Liutold's wife Heilwig (of Leuchtenberg?) is uncertain; Konrad's first wife appears only in 1220. A Plain daughter, Sophie, is the second wife of Count Otto of Lebenau.
- Confidence
- medium
de.wikipedia (Grafen von Plain), which warns that many dates are uncertain; en.wikipedia (Otto I, Duke of Bavaria) for Agnes.
Overlord
Their county rights round Salzburg are held of the duke of Bavaria or the Empire (not pinned); they hold advocacies and fiefs of the archbishop and the Salzburg churches; Hardegg is held under the duke of Austria.
What it holds
- The Plainburg above Großgmain (built about 1100)
- Höglwörth, the canons' house founded by Werigand in 1123, of which they are advocates
- Comital rights in the country west of the Saalach and Salzach round Teisendorf, Ainring and Freilassing (the later Rupertiwinkel), extent not pinned for 1200
- Advocacy of St Peter's abbey in Salzburg (held by Liutold I, died 1164)
- Advocacy of Berchtesgaden (from 1190), of Frauenchiemsee (about 1178) and of Herrenchiemsee
- The county of Hardegg in Lower Austria (from 1187-88): see the Austria file
How it was acquired
Plain from about 1100 (Werigand, named of Plain in 1108); Hardegg by 1187-88 (how, not stated in the source).
Allies and rivals
Kin of the Wittelsbach duke through Agnes; linked by marriage to the counts of Lebenau; Salzburg's advocates but also its burners in 1167; neighbours of the counts of Peilstein at Reichenhall.
How things stand that morning
Liutold and Konrad hold the Plainburg, Höglwörth and their advocacies together. Konrad's mother, the duke's sister, is alive on 1 January and dies on 13 January 1200 (en.wikipedia). No throne-war act of theirs is recorded for 1198-1199.
Wealth
Advocacy dues from rich churches, the county's courts and their estates; the Hardegg lands on the Moravian border.
Military
The Plainburg and their vassals; their men burned Salzburg in 1167 under Liupold. No campaign is pinned for 1199.
Threats
- The archbishops' wish to recover the advocacies
- Division between two young cousins
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.
- 13 January 1200Agnes of Wittelsbach, Konrad's mother, dies (en.wikipedia; the Plain genealogy says about 1200).Depends on: Nature. Stopped by: Nothing likely.
- 1200 (day not pinned)Konrad is styled count of Hardegg beside Liutold.Depends on: The cousins' sharing of the inheritance. Stopped by: A partition or a quarrel between them.
- 8 April 1200 onwardsAdalbert's death puts the Salzburg advocacies in play under a new archbishop who will claw back advocacies (Eberhard II's policy).Depends on: Adalbert's death. Stopped by: Adalbert living.
Places of note
- Höglwörth: Canons' house founded 1123 by Werigand of Plain
Where the sources disagree
- Agnes of Wittelsbach: married 1186 and died 13 January 1200 (en.wikipedia, Otto I of Bavaria) against married before 1177 and died about 1200 (de.wikipedia, Grafen von Plain).
- The Austria file (Hardegg) makes Konrad Liutold's brother and gives Otto's death as 23 August 1197; the de.wikipedia list read here makes Konrad (and Otto) sons of Henry I, so Liutold's cousins. Not settled.
Evidence: The family and its advocacies are documented; the genealogy around 1200 has unresolved points; the territorial extent of their county in 1200 is not pinned and is drawn from the later Rupertiwinkel.
On the map: Drawn from the later Rupertiwinkel south of Laufen; the Plains' rights were courts and advocacies among the archbishop's estates, not a closed block.
