CALAIS Calaisis (pays).
Port in northern France.
It belonged to the County of Boulogne until 1180 and then to the French King; the Calaisis south of the town was held by the Counts of Guines. In 1347 Calais was captured by Edward III of England after a long siege and remained an English territory until 1558. It was represented in Parliament, 1536-58, as part of a process of integrating the outlying lands of the realm fully into the Kingdom.
The Calaisis was known after 1558 as the Pays reconquis.
In the Ancien Régime Calais belonged to the petit gouvernement of Boulonnais and to the généralité of Amiens. In 1790 it was included in the Department of the Pas-de-Calais (which only indirectly bore its name, Pas-de-Calais being the French equivalent of Straits of Dover).
