What year is Boardwalk Empire set in? The show's full timeline
Boardwalk Empire takes place during the Prohibition era in the United States — roughly the 1920s and early 1930s — but each season zeroes in on a specific slice of that period.
The show ran for five seasons on HBO ( 2010–2014), starring Steve Buscemi as Enoch "Nucky" Thompson, a political boss who controls Atlantic City through a combination of charm, corruption, and bootlegged alcohol.
Here's exactly when each season is set.
Season by season
- Season 1 (12 episodes) — January to November 1920. The series opens on the very night Prohibition takes effect. Nucky sees an opportunity, and the empire begins.
- Season 2 (12 episodes) — February to August 1921. Nucky's power is challenged from multiple directions, and the body count starts to climb.
- Season 3 (12 episodes) — New Year's Eve 1922 to June 1923. New alliances, new enemies, and Nucky's world gets considerably more dangerous.
- Season 4 (12 episodes) — February to August 1924. The story widens with storylines stretching to Chicago and Harlem.
- Season 5 (8 episodes) — April to October 1931. A seven-year time jump lands us in the Great Depression, with Prohibition nearing its end. This final season also features flashbacks to 1884 and 1897, showing Nucky's childhood and early life.
The big picture
In total, the main storyline spans from January 1920 to October 1931 — just over eleven years. With the flashbacks, the show touches on nearly five decades of American history.
The seven-year gap between seasons 4 and 5 is worth noting. The show skips over the late Roaring Twenties entirely, jumping straight to the era's hangover. If you're watching and suddenly wondering why everything looks grimmer and everyone looks older, that's why. Showrunner Terence Winter has said the plan was always to bookend the series with the beginning and the end of Prohibition.
Across all five seasons, there are 56 episodes in total (the final season is shorter at 8, while the first four have 12 each). The entire show is finished, so you can watch it all without waiting for anything.
