rule the roost

Be in charge, boss others, as in In our division the chairman's son rules the roost. This expression originated in the 15th century as rule the roast, which was either a corruption of rooster or alluded to the person who was in charge of the roast and thus ran the kitchen. In the barnyard a rooster decides which hen should roost near him. Both interpretations persisted for 200 years. Thomas Heywood (c. 1630) put it as "Her that ruled the roast in the kitchen," but Shakespeare had it in 2 Henry VI (1:1): "The new-made duke that rules the roast," which is more ambiguous. In the mid-1700s roost began to compete with roast, and in the 1900s roost displaced roast altogether. Also see run the show.

rule the roost, to

To be the boss. This term originated as rule the roast in the fifteenth century. Possibly it even then referred to the rooster, who decides which hen should roost near him. On the other hand, Thomas Heywood, in his History of Women (ca. 1630), stated, “Her that ruled the roast in the kitchen,” so perhaps it did mean whoever held sway over the kitchen, the heart of a household. Shakespeare used it more broadly, however. In Henry VI, Part 2 (1.1) he refers to “the new-made duke that rules the roast.” In any event, it has been used for bossing anything from a family to an entire nation.
