Kingdom of Crotona

The Kingdom of Crotona was a crownland of the Apostolic Kingdom of Urcea established out of Urcean territories on Crotona in 1660. It was dissolved during the Crown Regency of Gréagóir FitzRex and divided into four provinces - North Crotona, South Crotona, Tromarine, and Halfway - during the era of the Red Interregnum.

The Kingdom was created from a constellation of minor territories, vassals, and dependent free cities on the island of Crotona which had been acquired piecemeal by Urcea since the 13th century. The Principality of Halfway, Urcea's key possession in the Sea of Canete and previously a mostly autonomous holding, was also incorporated. Tromarine was intended to be added to the Kingdom upon its foundation, but the complete envelopment of the island by Urcea did not occur until 1676, when it was incorporated into the Kingdom.

The establishment of the Kingdom had the effect of centralizing control over the island and improving its economic condition due to the removal of internal tariffs and trade barriers. It also lead to the concentration of industrial and mercantile interests around Toulonium, its, leading to the development of that city into one of Urcea's largest metropolitan areas.
