Overlord
Alfonso VIII of Castile
How things stand that morning
Royal and quiet.
Wealth
Sheep and wool, with flocks moving each year between the summer grass of the sierras and the winter pastures of the Tajo and La Mancha (transhumance). The Mesta, the royal guild of the herders, is a creation of 1273 and does not exist yet. The see's tithes and the Ucero mills.
Military
Castle of Osma on its hill. Alarcos (19 July 1195): Alfonso VIII fought with his household, the magnates and town militias; the sources used here do not say whether this town's militia was in the field.
Council
One concejo for the town and its villages (a comunidad de villa y tierra): the vecinos of the town and the aldeas share one council that meets in the town, chooses its judge (juez) and alcaldes each year by parish (collación), and governs common pasture, woods, justice, walls and the host. The villages are grouped in districts (sexmos, cuartos or ochavos); most of these district names are recorded later than 1200.
Communities
Castilian settlers; the cathedral chapter living under a rule.
Fairs and markets
Market at El Burgo; none pinned.
Militia
Town militia (milicia concejil): non-noble horsemen (caballeros villanos) who keep a horse and arms in return for tax privileges and a share of office, plus foot. It rides in the king's host and in its own raids (cabalgadas) toward the Tajo and the Guadiana.
Places of note
- El Burgo de Osma: the bishop's cathedral town
Where the sources disagree
Evidence: Church side from the campaign notes; the royal castle's holder not pinned.
On the map: Tierra drawn as seeds from the villages of the comunidad as recorded in the 13th to 15th centuries (Martínez Díez); the 1200 edges were not surveyed lines, and some villages were still being founded or quarrelled over. Treat the outline as approximate.
