The originality of the bastides lies in their charter, granted by the sovereign. It is a document on parchment, written in Latin, signed by the king and marked with his seal. Whether they are French or English, they are all written on the same model. The principle of the charter has been known since the 11th century, when some were granted by kings or abbeys. But it was Alphonse de Poitiers, brother of Louis IX, who gave them the rigour and definitive form known at the end of the 13th century.
Molières is no exception to the rule. Edward I granted it its charter on 20 November 1286, when the bastide was already built. This text is not exceptional, it is similar to that of other bastides. It was confirmed by François I and Henri II by letters patent in 1533 and 1551.
The boldness of these documents is an originality of the time: they are true municipal codes marking a return to the written law of the Romans. It was feudalism that was being undermined. The serf bound to the lord was gradually replaced by the citizen belonging to a semi-urban, semi-rural community. The members of this community are united by the same duties and rights defined in this document. This official text is a guarantee of freedoms and privileges, but it also precisely determines the fees and duties required of the new citizens.
