The Fantastic Beasts series is set in the 1920s and 1930s, decades before the events of the Harry Potter series. Here is a timeline of the Fantastic Beasts series:

• 1926: Fantastic Beasts and Where to Find Them
• 1927: Fantastic Beasts: The Crimes of Grindelwald
• 1937: Fantastic Beasts: The Secrets of Dumbledore

The events of the Fantastic Beasts series are significant for the Harry Potterverse as a whole, and the franchise is expected to continue to explore the first half of the 20th century. The relationship between Albus Dumbledore and Gellert Grindelwald is also expected to play a large role in the coming films.
