By the late 19th century, Christmas in Manhattan was an excuse for the rabble to go wilding from door to door in upper-class neighborhoods, demanding booze and cash from terrified householders in exchange for an off-key (and sometimes off-color) yuletide song. In desperation, Washington Irving, Clement Clarke Moore, and other members of New York's cultural elite invented Santa Claus---and Christmas as we know it---as a means of domesticating the drunken revels of the dangerous classes. Their bourgeois myth was designed to channel lumpen unrest into a more acceptable outlet: a domestic ritual consecrated to home, hearth, and conspicuous consumption.
