Abstract
Early modern London burned quantities of dirty coal that were unparalleled anywhere in Europe before industrialization, and the consequent smoky air was a matter of more serious and sustained concern than has been appreciated by either early modern or environmental historians. During the 1620s and 1630s, King Charles I and his government sought to remove smoky industries, above all large brewhouses, from the vicinity of the court in Westminster. This was part of a broader campaign for order and beauty that has been described by other scholars, but a focus on smoke highlights the very partial successes achieved by attempts to reform the real spaces of royal government. The improvement of Westminster's air during Charles's personal rule displays an early modern variety of environmental concern that was expressed through courtly display, hierarchy, distinction, and exclusion.
