Only a Select Few Were Permitted Out After Dark
To talk about the night watch, we first have to talk about night itself. In a pre-industrial world, artificial light was expensive. Candles of tallow and beeswax are animal products, so can be produced only in limited amounts. Firewood, peat, and dried dung are labor-intensive to gather and prepare. So too is olive oil or flaxseed oil for lamps. Before gas and kerosene, you could light the night if you really wanted—but it would cost you. Consequently, nights stayed dark. Most Europeans were home by twilight, barred their doors, and stayed indoors. In the Middle Ages, many cities imposed curfews: only a select few were permitted out after dark. This cut down both on burglaries and people breaking their necks falling into open cellars.
But having an entire city asleep posed its own problems. The biggest was fire! Medieval European cities were tinderboxes. Entire city blocks burned down every year. And if no one was awake at midnight when someone’s improperly-banked coals set their house on fire, the blaze might spread to multiple houses before anyone even noticed. Plus, you had the problem of crime: if no one else was about after dark, that gave thieves full run of the night. The solution to these problems (and honestly more the former than the latter) was the night watch.
Many night watches began as citizen’s brigades, with each able-bodied male resident assigned to patrol the streets so many nights a year. As early as 1150, the guilds of Paris were on the hook for providing the city’s watchmen. Sentinels sat in the tallest church steeple in town to watch for fires. (Amsterdam was big enough that the watch manned four separate steeples!) Other watchmen patrolled the streets alone or in pairs watching for fires and thieves. Your beat might cover the whole city or just your own neighborhood. If you saw a fire, you set up a cry so sleepers could awaken and help put it out. If you saw a burglar, you tried to grab him so he could appear before a magistrate in the morning. For worse crimes, you also started the ‘hue and cry’ to summon your sleeping neighbors to help. This watch system, while practical, was unpopular. No one much liked being a watchman. If you could afford it, you hired a substitute to take your place….
