What is the title of the episode about the Great Smog of 1952?

The episode about the Great Smog of 1952 is titled “Act of God.” It is the fourth episode of Season 1 of The Crown, written by Peter Morgan and directed by Julian Jarrold. In the story, a dense smog paralyses London and creates a political crisis for Prime Minister Winston Churchill.

The real Great Smog occurred in London from December 5 to 9, 1952. Cold, windless weather trapped smoke and sulfur dioxide from coal fires and industrial sources close to the ground. Visibility collapsed, transport was disrupted, and the event contributed to thousands of deaths. Modern estimates place the death toll far above the early official estimate of about 4,000.

The episode connects the environmental disaster with Churchill’s government and Queen Elizabeth II’s early reign. Its title comes from the political language used to describe the crisis, not from the official name of the historical event. “Smoke and Mirrors” and “Wolferton Splash” are titles of other episodes.
