In "A Distant Mirror: The Calamitous 14th Century," Barbara W. Tuchman discusses the feudal system and land ownership dynamics during the 14th century. One notable example is the fief of Coucy, which was historically associated with the Church. Over time, this fief became directly accountable to the King, indicating a shift in power and influence, as the seigneur of Coucy was required to pay homage solely to the King.

This transformation reflects the broader changes within feudal structures, where the authority of the monarchy grew stronger while traditional ties to the Church weakened. Tuchman illustrates how land holdings and loyalty shifted during this tumultuous period, highlighting the evolving relationships between lords and the crown amidst the challenges of the century.
