A family of rural counts in the Apennine valleys round Fabriano and Matelica, of the kind the March towns were busy swallowing.
After Christian of Mainz wrecked Matelica (1174-1175), the sons of an elder Count Atto swore fidelity, apparently to the rebuilt commune. About 1199 a later Count Atto turned on Matelica and put together the league of Camerino, Fabriano, San Severino, Tolentino, Cingoli, Recanati and Civitanova that destroyed the town. On 1 January 1200 he is presumably the strongest lord in the hills round the ruined town, allied with Fabriano and Camerino, though which castles he holds is not documented.
Who he is
- Name
- Count Atto (Attone), descendant of the elder Count Atto whose sons swore fidelity after 1174
- Title
- Count
- Since
- not pinned
- Born
- Not pinned
- Family
- A comital house of the uplands between Fabriano, Sassoferrato and Matelica; in the twelfth century the counts Atto held the castle of Precicchie (now in Fabriano's territory) before it passed to the Rovellone (date not pinned).
- Confidence
- low
The Italian Wikipedia history of Matelica says the sons of Count Atto swore fidelity after 1174 and that a later Count Atto organised the league that destroyed Matelica about 1199; the Italian Wikipedia history of Fabriano names the counts Atto as twelfth-century holders of Precicchie. Neither gives the count's own name beyond Atto or his castles in 1200. Whether this house is the ancestor of the later Atti of Sassoferrato is not pinned.
Overlord
The pope, as lord of the March; earlier the emperor.
What it holds
- Castles in the hills between Fabriano and Matelica (not pinned for 1200)
- Precicchie (held by the counts Atto in the twelfth century; whether still theirs in 1200 is not pinned)
How it was acquired
Inherited comital lordship of the eleventh and twelfth centuries (not documented in detail).
Allies and rivals
Allies: Camerino, Fabriano, San Severino, Tolentino, Cingoli, Recanati and Civitanova in the league of 1199. Rival: Matelica.

Threats

- Matelica's revenge if it is rebuilt
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.
- 1209 (not 1200)The Matelicesi, appealing to Otto IV, are allowed to rebuild their town.Depends on: A new emperor's favour. Stopped by: The league towns holding Matelica's land.
Where the sources disagree
Evidence: Known only from the Italian Wikipedia histories of Matelica and Fabriano, which cite no document for 1199; the Matelica account also contains a clear error (it has 'Frederick II' make peace with the pope in 1185).
On the map: Not drawn: the count's castles in 1200 are not known.
