The warrior who stands for Kamakura in the south.
Tadahisa was given Shimazu-no-shō, the huge estate of the Konoe regents that runs through Hyūga, Ōsumi and Satsuma, as its steward, and made constable of Satsuma; by the house tradition his charge grew to include Ōsumi and Hyūga, and he came south in 1196, subdued the two provinces and built a castle in the Shimazu district, whose name he took (English Wikipedia). He rules through deputies (the Honda for Satsuma) and through the older local families. The Konoe name stands on the revenue; his name is on the army.
In Kamakura he is a Hiki connection: his tie to Hiki Yoshikazu will cost him his offices after the Hiki incident of 1203 (recollection).
Who he is
- Name
- Shimazu Tadahisa
- Title
- Steward (jitō) of Shimazu-no-shō and constable (shugo) of Satsuma, Ōsumi and Hyūga, by house tradition
- Since
- Named constable of Satsuma in 1186 and went south in 1196 (English Wikipedia, Shimazu clan); the three-province charge is dated 1196 or 1197 in the house genealogies
- Born
- traditionally about 1179; on the likely course he dies in 1227 (English Wikipedia gives the death)
- Family
- Claimed son of Minamoto no Yoritomo by a sister of Hiki Yoshikazu; the same page notes that he was probably head steward (a household officer) of the Konoe family before he claimed Genji descent. Married a daughter of Koremune Hironobu and first used the name Koremune. Shioda in Shinano is his home estate
- Confidence
- medium
English Wikipedia (Shimazu Tadahisa; Shimazu clan). The three-province charge is a house tradition and the date is marked as such in the brief.
Overlord
Minamoto no Yoriie (Kamakura); the Konoe regent house as proprietor of the estate
What it holds
- Shimazu-no-shō (Konoe's estate) as steward, with the Shimazu-in in the Miyakonojo basin as headquarters
- The constable's rights over Satsuma, Ōsumi and Hyūga (house tradition)
- Shioda in Shinano (home estate, held by deputies)
How it was acquired
1185 and 1186 by Yoritomo's grant (the date of the steward's grant rests on recollection); 1196 or 1197 by the house tradition for the south in full.
Allies and rivals
Allied with Hiki Yoshikazu (by the tradition) and the Honda deputies; rivals: local families of Satsuma (the Ata, Kawabe and others, whose names are not checked here), the Ōtomo in the north, and the Aso and Usa estate-men.
How things stand that morning
Newly in the saddle. The offices stand on a house tradition; the province's old local families still hold the ground. There is no war but the hold is loose, and no source here shows raids.
Wealth
The estate revenue of the Konoe, shared with the steward; no figure used.
Military
Tadahisa's own housemen, the Honda deputies and the local families he has taken into the service; no numbers.
Threats
- Local families resisting a steward from the east
- The fall of his Hiki kin in 1203 (later)
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.
- 1203, after the Hiki incident (Kennin 3/9/2, 8 October 1203 Julian)Tadahisa loses his constable's posts for his ties to Hiki Yoshikazu; Satsuma and Ōsumi are later restored to him (recollection)Depends on: The Hiki fall depends on the Hiki and Hōjō quarrel, which is not in view on 1 January 1200 Stopped by: No Hiki incident
Places of note
- Shimazu-in: Headquarters of the estate in the Miyakonojo basin (Hyūga)
- Kokubu: Ōsumi's provincial seat, in his charge by tradition
Where the sources disagree
- Board: 'has held the south since 1196' as fact. English Wikipedia gives 1186 for Satsuma and 1196 for his arrival; the three-province charge is a house genealogy (brief).
Evidence: English Wikipedia (two pages) for the main facts; the house tradition is marked; the 1203 loss is recollection.
On the map: Shown as held at the headquarters and claimed in the two provinces whose hold is a house tradition.
