"From our ancient records, it seems that burghs and burgesses were held in respect and humour, and their trade encouraged and protected."
Arnold F McJannet

The seven trades of Irvine - Hammermen, Weavers, Tailors, Cordiners, Skinners, Wrights and Squaremen and Coopers were well established for generations before the granting of the Seal Of Cause.

In 1424, in the reign of James 1, it was decreed by Act of Parliament that each TRADE should choose a 'DEKYN' or 'MASTER' to control the quality of craftsmanship within his own particular trade. Mary, Queen of Scots, gave permission in 1556 for two craftsmen to serve on the high burgh council enabling the crafts to have a secure footing in the local government of the day.
