Minerva McGonagall

Verified Timeline

Lore & Background

McGonagall is introduced at the beginning of Harry Potter and the Philosopher's Stone (1997) when she accompanies Albus Dumbledore as he delivers the infant Harry Potter to the Dursley residence. When Harry arrives at Hogwarts a decade later, he meets McGonagall, who is the Transfiguration professor and the head of Gryffindor House. After noticing Harry's broomstick flying skills, McGonagall introduces him to the Gryffindor Quidditch team captain Oliver Wood. Once Harry qualifies for the Quidditch team, McGonagall buys him a Nimbus 2000 broomstick. In Harry Potter and the Chamber of Secrets (1998), McGonagall becomes acting headmistress after Dumbledore is suspended by the Ministry of Magic. When she discovers that Ginny Weasley has been taken into the Chamber of Secrets, she orders Professor Gilderoy Lockhart to rescue her. After Lockhart proves incompetent, Ginny is saved by Harry and Ron Weasley. At the beginning of Harry Potter and the Prisoner of Azkaban (1999), McGonagall gives Hermione Granger a Time-Turner to allow her to take multiple classes at the same time. After Harry's Nimbus 2000 is destroyed, he is sent a Firebolt, but McGonagall confiscates it. She suspects it is cursed, but eventually finds it to be safe. In Harry Potter and the Goblet of Fire (2000), McGonagall is concerned for Harry's safety when he is mysteriously selected for the Triwizard Tournament. After the death of Cedric Diggory, she joins Albus Dumbledore and Severus Snape in rescuing Harry from the Death Eater Barty Crouch Jr. McGonagall joins the secret organisation Order of the Phoenix in Harry Potter and the Order of the Phoenix (2003). After the Ministry-appointed Defence Against the Dark Arts professor Dolores Umbridge refuses to teach students practical defensive magic, McGonagall supports Harry, Ron and Hermione as they form the self-defence group Dumbledore's Army. While attempting to protect Rubeus Hagrid from Umbridge, McGonagall is assaulted by Aurors and sent to St Mungo's Hospital. She eventually recovers and returns to Hogwarts before the end of the school year. In Harry Potter and the Half-Blood Prince (2005), McGonagall duels with the Death Eater Alecto Carrow during the Battle of the Astronomy Tower. McGonagall is appointed headmistress after Dumbledore's death, but is replaced by Snape when Voldemort takes control of Hogwarts in Harry Potter and the Deathly Hallows (2007). She continues to teach, and is present when Harry, Ron and Hermione return to Hogwarts searching for Ravenclaw's diadem. Soon after, McGonagall banishes Snape from Hogwarts. She prepares the school's defences prior to Voldemort's assault, and helps evacuate the younger students to Hogsmeade. During the Battle of Hogwarts, McGonagall duels with Voldemort alongside Horace Slughorn and Kingsley Shacklebolt.

In Their Own Story

The wind howled through the shattered windows of the Great Hall, carrying the scent of smoke and ozone. McGonagall stood before the remaining defenders, her wand raised high, her tabby form flickering briefly in the chaos before solidifying into human resolve. "Hogwarts is under attack!" she commanded, her voice cutting through the panic with the precision of a scalpel. With a sharp crack, she transfigured stone gargoyles into living warriors to reinforce the front lines. Her eyes, sharp and unyielding behind their square frames, scanned the battlefield, finding every student in need and directing them to safety without hesitation. In that moment, she was not just a teacher; she was the shield of the school itself.
