By the 14th century Birmingham seems to have been established as a particular centre of the wool trade. Two Birmingham merchants represented Warwickshire at the council held in York in 1322 to discuss the standardisation of wool staples, and others attended the Westminster wool merchants assemblies of 1340, 1342 and 1343, a period when at least one Birmingham merchant was trading considerable amounts of wool with continental Europe. Aulnage records for 1397 give some indication of the size of Birmingham's textile trade at the time, the 44 broadcloths sold being a tiny fraction of the 3,000 sold in the major textile centre of Coventry, but making up almost a third of the trade of the rest of Warwickshire.
