The postglossators or commentators formed a European legal school which arose in Italy and France in the fourteenth century.
Politically at this time, the idea of the Spirit of One – one church and one empire, was popular in Europe.
They were opportunistic and as medieval Italy flourished, there were many opportunities to be the mediator between the developing political, scientific and economic spheres.
Thus many of their ideas were based on practical morality, bold construction of the law and clever interpretations.
The Commentators said that the canon law was simply a form of clothing which could make a bare pact enforceable.
The extraction of general principles allowed Roman law to be used in situations which were unfamiliar to the Romans, it provided a coherent and convenient set of rules, which could then be used to interpret local customs, which were given primacy but very narrowly interpreted.
