Historically, it was recognised that there was a need to difference the arms of the head of the family from those of cadets. This need was recognised in Europe during the 14th century; various means to accomplish this were used.

In the modern era, differencing arms is generally rarely done in continental Europe. It is only in Scotland where the need to difference cadets is enforced.
