It was first formed in 1892 in Halifax, West Yorkshire, later expanding to cover all of Northern England.
The NCTU was formed later than the Power Loom Carpet Weavers' and Textile Workers' Association, based in Kidderminster, and was considerably smaller.
Approximately a fifth of eligible workers were members of the NCTU in 1939, compared to 50 percent for the Kidderminster union.
