In the manufacture of silk, women early appear as independent producers and manufacturers, for in the fifteenth century they were sufficiently organised to be able collectively to petition Parliament for measures to check the importation of ribbons and wrought silk, and on their behalf was passed an Act (1455) 33 Hen. VI. c. 5, which states that "it is shewed ... by the grievous complaint of the silk women and spinners of the mystery and occupation of silk-working, within the city of London, how that divers Lombards and other strangers, imagining to destroy the said mystery and all such virtuous occupations of women in the said realm, to enrich themselves and to increase them and such occupations in other strange lands, have brought and daily go about to bring into the said realm such silk so made, wrought, twined, ribbands and chains falsely and deceitfully wrought, all manner girdels and other things concerning the said mystery and occupation, in no manner wise bringing any good silk unwrought, as they were wont to bring heretofore, to the final destruction of the said mysteries and occupations, unless it be the more hastily remedied by the King's Majesty." The importation of silk, ribbons, etc., was forthwith prohibited, and we find similar prohibitions in 3 Edw. IV. c. 3 and c. 4, 22 Edw. IV. c. 3, 1 Rich. III. c. 10, and 1 Hen. VII. c. 9. Henry VII. dealt with several silk women for ribands, fringes, and so forth, as recorded in his accounts. A statute of Charles II. 14 Ch. II. c. 15 says many women in London were employed in working silk. The manufacture of silk was introduced into Derbyshire at the beginning of the eighteenth century. John Lombe's silk mill was the first textile mill at work in that county. A rather considerable manufacture of piece silks and silk ribbons and braid grew up in Derby and Glossop, a large proportion of women and girls being employed. The numbers of operatives in this industry increased up to the census of 1851 and 1861, when about 6000 operatives were employed, after which it began to go down, reaching the low figure of 662 in the county in 1901; in 1911, 442.
