The infographic seen here covers the important events in the world of Harry Potter from 1881 through 1956, which starts with the birth of Albus Dumbledore and ends when Lord Voldemort returned to Hogwarts after he graduated and asked for a job teaching Defense Against The Dark Arts. As we all know, his request was denied but he took the opportunity of being in the castle to hide his Ravenclaw diadem Horcrux in the Room of Requirements.
You might be wondering why this graphic ends at 1956. To be honest, the graphic would have been ridiculously long had I included all events so I decided to create multiple timeline infographics.
