The county of Forez is the upper Loire plain and its rim of hills, between the Auvergne mountains and the Lyonnais.
Guy II, once count of Lyon too, gave up his rights in Lyon to the archbishop by the exchange (permutatio) of 1173 and took the Church of Lyon's lands in Forez in return, so the counts now rule a compact county from Montbrison and Feurs. In 1198 the old count handed it to his son Guy III, whose brother Renaud is archbishop of Lyon. The counts fight the lords of Beaujeu, who covet the Roannais and the northern Forez.

Overlord
Philip II, king of France (the counts of Forez placed themselves under the crown in the reign of Louis VII); the archbishop of Lyon, the count's brother, is his neighbour and partner since the exchange of 1173
What it holds
- Montbrison castle and town, the comital seat
- Feurs, the old Roman capital that gave Forez its name
- Saint-Galmier, Sury, Saint-Bonnet and the castles of the plain
- the Roannais up to the Beaujolais border (Roanne's lordship in 1200 not pinned)
- overlordship of the Jarez lords toward Saint-Etienne (not pinned)
How it was acquired
Inheritance; the 1173 exchange with the Church of Lyon defined the county.
Allies and rivals
Allied to the archbishop of Lyon by blood; rival of the Beaujeu; neighbour of the count of Auvergne and the lords of Thiers.
How things stand that morning
Guy III rules the county; his father lives on in retirement. East lies the Lyonnais of Archbishop Renaud (imperial city and Church lordship); north the Beaujolais; south the Velay (bishop of Le Puy) and the Vivarais (Southeast researcher).
Wealth
The Loire plain's grain and cattle, the Montbrison market, tolls on the Loire and on the road from Lyon to Clermont.
Military
Montbrison castle and the castles of the plain.
Threats
- Beaujeu ambitions in the Roannais
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 (later course)Guy III dies at Acre soon after arriving in the Holy Land; Guy IV succeeds young under the guardianship of his uncle Archbishop Renaud.Depends on: Guy III taking the cross and going east Stopped by: his staying at home
Places of note
- Montbrison: comital castle and seat
- Feurs: old capital of the Forez
Where the sources disagree
- The assignment names Guy II as count; fr.wikipedia's Guigues III and its list of counts both put Guy III in office from 1198 after his father's abdication. Guy III is followed; the abdication's day is not pinned.
- fr.wikipedia's list gives Guy II's death as 1226, which seems too late; other works give 1206.
Evidence: Succession by year is clear; the county's extent follows the later county of Forez.
On the map: The Church of Lyon's enclaves (Savigny's lands, the Hospitallers of Chazelles) and the Jarez lordships are approximate.

Ends in 1195, so it has no 1200 entries, but it is the indispensable background for Flanders and Hainaut: the career of Count Baldwin V of Hainaut (VIII of Flanders), his union of the two counties, the settlement with Philip over Artois, the rights, castles, fiefs and vassals of Hainaut listed by a man who ran its chancery, and the youth of Baldwin IX, who held both counties in 1200.
