The Great Stink of London in 1858.

One summer the heat dried up the River Thames (where all the human waste went) and an unbearable smell pervaded throughout the entire city. All Parliament representatives were eventually coerced out of their homes outside of London to convene and solve the issue. Much to the citizens’ glee, Parliament was held in their building on the bank of the River Thames, resulting in one of the fastest Parliament decisions ever made to reform the London sewer system.
