By the 17th century land-owning farmers were finding it increasingly difficult as were their landlords and some payments were still in kind as farmers had no money to pay their debts. Meanwhile, the textile workers were becoming more and more prosperous and paid less and less attention to their hard up and increasingly impotent landlords. During the English Civil War the clothiers were on one side and the landlords on the other. Lords of the area were made Royalist officers and made some progress such as at the Battle of Adwalton Moor about a mile east of Birkenshaw and the siege of Bradford, before the Parliamentarians took control of the area. Royalist families were forced, after the war, to pay large fines to keep their lands and avoid imprisonment. All the time clothiers were growing wealthier and by the end of the 17th century more than half of the wills in the parish of Birstall came from men whose wealth came from textiles.
