Potter Verse Canon

First wizard War

1970 - 10/31/1981

"Imagine that Voldemort's powerful now. You don't know who his supporters are, you don't know who's working for him and who isn't; you know he can control people so that they do terrible things without being able to stop themselves. You're scared for yourself, and your family, and your friends. Every week, news comes of more deaths, more disappearances, more torturing… The Ministry of Magic's in disarray, they don't know what to do, they're trying to keep everything hidden from the Muggles, but meanwhile, Muggles are dying too. Terror everywhere… panic… confusion… that's how it used to be."
—Sirius Black on the war[src]
The event known as the First Wizarding War was a major conflict with foundations as early as the 1940s, but officially beginning in 1970 and ending abruptly in 1981. It marked the original "reign" of the Dark Lord Voldemort.
The Dark Lord's rebellion occurred with the help of his Death Eaters, Dark wizards and witches who served him and brought terror to both Muggle and magical innocents. They were opposed by the Ministry of Magic and the Order of the Phoenix, an organisation founded by Albus Dumbledore that would play a crucial role in both of Voldemort's defeats.

Quirinus Quirrell teaches Professor of Muggle Studies

09/1988 - 06/1990

actual start date is unknown
After teaching Muggle Studies for some time, he took a year-long sabbatical in 1990 in order to "gain first-hand experience",[4] though in reality he had taken a 'Grand Tour' around the world in order to hopefully find whatever remained of Lord Voldemort after his first defeat, partly out of curiosity, partly out of that unacknowledged desire for importance from his childhood. At the very least, Quirrell fantasised that he could be the man who tracked Voldemort down, but at best, might learn skills from Voldemort that would ensure he was never laughed at again. His journey proved successful as he did indeed find Voldemort, though he was no match for the Dark Lord (even in such a weakened state) and when he realised that Quirinus had a position at Hogwarts, Voldemort took immediate possession of Quirrell, who was incapable of resisting.

The decree was abolished after Dolores Umbridge's suspension from her post of High Inquisitor and Albus Dumbledore return to his post of Headmaster following the Battle of the Department of Mysteries, in the summer of 1996.
