Where did Dutch courage originate?
During the bubonic plague of London, the city was sealed off to avoid contamination. This meant no food was permitted in. The only people willing to trade with London were the Dutch, who left food on jetties and then would take the money left there. They used to steel their nerves with liquor before landing on the plague-infested shores, hence “Dutch courage.” To this day, the Dutch still have the freedom of the river Thames, which was granted as a reward for their courage and kindness.
