Wolsey also used his courts to tackle national controversies, such as the pressing issue of enclosures. The countryside had been thrown into discord by the entrepreneurial actions of landlords enclosing areas of land and converting from arable farming to pastoral farming, requiring fewer workers. The Tudors valued stability, and this mass urban migration represented a serious crisis. Wolsey conducted national enquires in 1517, 1518 and 1527 into the presence of enclosures. In the course of his administration he used the court of Chancery to prosecute two hundred and sixty-four landowners, including peers, bishops, knights, religious heads, and Oxford colleges. Enclosures were seen as directly linked to rural unemployment and depopulation, vagrancy, food shortages and, accordingly, inflation. This pattern was repeated with many of Wolsey's other initiatives, particularly his quest to abolish enclosure. Despite spending significant time and effort in investigating the state of the countryside and prosecuting numerous offenders, Wolsey freely surrendered his policy during the parliament of 1523 to ensure that Parliament passed his proposed taxes for Henry's war in France. Enclosures remained a Problem for many years.
