Gaeta, on its rock between two bays, was a duchy of its own until its last duke left it to Roger II in 1140.
It keeps a strong communal life under the crown. In July 1191, in Tancred's war, the commune was given the castles of Itri and Maranola, taken from the count of Fondi, who had sided with Henry VI (DBI on Riccardo dell'Aquila). On 1 January 1200 it is a royal port town governing its own coast, with no love for the count of Fondi, Diepold's ally next door; its stance in the war is not recorded.

Lord in 1200
The king. The commune governs itself under a judge chosen each year and several consuls, respects the king's lordship and runs its own affairs at home and abroad (it.wikipedia, of the early 13th century). The judge and consuls in office on 1 January 1200 are not pinned.
Overlord
The king.
Allies and rivals
Rival: the count of Fondi (Itri and Maranola). Neighbours: the papal Campagna and the Frangipani of Terracina; Montecassino's castles on the Garigliano.
How things stand that morning

Wealth
The port and the sea trade.
Military

Threats

Charter
Roger II, after taking the city in 1140, granted it privileges beginning with its own coinage, and Gaeta kept much of the standing of a sea republic, like Amalfi (it.wikipedia on Gaeta); Itri and Maranola were granted to the commune in July 1191 (DBI on Riccardo dell'Aquila). Whether its mint was striking coins in 1200 is not pinned.
Council
A yearly judge (iudex) and consuls [early 13th century].
Militia
The citizens and the town's ships.
Walls and castle
The walled town on the promontory, one of the strongest places on the coast.
Trade and crafts
Shipping and coastal trade along the Tyrrhenian; the harbour under the rock.
Where the sources disagree
Evidence: The commune's form is described for the early 13th century; the 1191 grant is in the DBI. Nothing dated for 1199-1200.
On the map: Gaeta with Formia (the old Mola and Castellone) and Itri and Maranola, granted to the commune in 1191; whether the count of Fondi recovered Itri by 1200 is not pinned.
