Calais (dated, Cales /ˈkæləs/) was a former constituency of the Parliament of England.
In 1360 the Treaty of Brétigny assigned Guînes, Marck and Calais – collectively the "Pale of Cales" – to English rule in perpetuity, but in a daring raid during the rule of Mary I, was retaken by France.
King Henry VIII of England decided to modify the arrangements for the government of Calais.
One member was to be nominated, elected and chosen by the Deputy (the king's representative in the town) and his council.
On 6 December 1557 a writ was issued for the election of members to an eleventh parliament, but before it met Calais had fallen to the French.
