The landgrave's own castles, towns and advocacies in Thuringia: the Wartburg and Eisenach, the Creuzburg on the Werra, Gotha, the Tenneberg with the house monastery of Reinhardsbrunn, the Runneburg at Weissensee, Thamsbrück on the Unstrut, the Neuenburg above Freyburg and Eckartsberga in the east, old Ludowingian Sangerhausen, the Ebersburg in the southern Harz and (medium confidence) Schmalkalden.
This is the heart of the landgraviate; the counts' lands and Mainz's Erfurt lie between its pieces.

Overlord
The king. The Ebersburg is held of the archbishop of Mainz (sold to Archbishop Conrad and taken back in fief, charter of 1189-90).
What it holds
- The Wartburg (main residence by the late 12th century) and the town of Eisenach below it
- The Creuzburg: the provostry came to the Ludowingians in 1137; Hermann began a castle on the hill; the Werra crossing (the stone bridge is of 1223, later)
- Gotha, a landgrave's town by 1180-89 and one of his main mints
- The Tenneberg above Waltershausen and the advocacy of Reinhardsbrunn, the family monastery and burial place
- The Runneburg at Weissensee, begun in 1168
- Thamsbrück on the Unstrut
- The Neuenburg above Freyburg on the Unstrut and the castle of Eckartsberga
- Sangerhausen, old Ludowingian land since Louis the Springer, a village given town rights in 1194 (the landgrave's hold in 1200 is medium confidence)
- The Ebersburg near Herrmannsacker, built 1181-83 by Hermann as count palatine, a Mainz fief since 1189-90
- Schmalkalden with the castle Waltaff (12th century): Ludowingian until 1247, when it went to Henneberg; the landgrave's hold in 1200 is medium confidence (the place is destroyed in the throne war in 1203, not yet)
- Rights as landgrave: the peace court of the land (the landding) over the Thuringian counts
How it was acquired
Inherited from the Ludowingian landgraves (Louis the Springer built the Wartburg, traditionally 1067; landgrave's title from 1131).
Allies and rivals
Allies: his ministeriales and the counts who attend his court. Rivals: the archbishop of Mainz's Erfurt, the counts of Gleichen (Mainz's advocates, enemies until 1178, reconciled since), the Welfs to the north.
How things stand that morning
Held without challenge by Hermann, who backs Philip since 15 August 1199. No fighting in these lands that winter.
Wealth
Markets and mints of Eisenach and Gotha; tolls on the east-west road (the later Via Regia) from Eisenach through Gotha to Erfurt; the Werra crossing at the Creuzburg; the forests of the Thuringian Forest; the Unstrut grain lands round Weissensee and Thamsbrück.
Military
The castles listed; ministeriales of Vargula, Schlotheim, Fahner, Eckartsberga and Ebersburg. No numbers.
Threats
- A Welf raid from the north on the Harz edge and the Ebersburg
- A contested Mainz succession after Conrad's death
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.
- 28 October 1200Birth of Louis at the landgrave's court.Depends on: Sophia conceiving about February 1200 Stopped by: Miscarriage or separation of the couple

Where the sources disagree
Evidence: The main castles and towns are well known; Sangerhausen and Schmalkalden in 1200 are less certain.
On the map: Only the main castle districts are drawn; the landgrave's scattered villages and advocacies across the Thuringian basin are not.
