Amycus Carrow was born sometime before 1981 into the pure-blood Carrow family, somewhere in the British Isles. At some point before his instruction in the magical arts, he acquired a wand.
Given that he seemed to have been acquainted with Albus Dumbledore, it is possible that he attended Hogwarts School of Witchcraft and Wizardry in his youth.
First Wizarding WarEdit
Amycus and his sister supported Lord Voldemort, and became Death Eaters during the First Wizarding War. After Voldemort's downfall in 1981, they did not search for their master, believing that Voldemort was gone forever, and managed to avoid imprisonment in Azkaban.
Despite all this, the Carrows were among those who, after Voldemort's return, resumed their Death Eater activities. The two siblings were fairly active during the Second Wizarding War.
Second Wizarding WarEdit
Rebirth of the Dark LordEdit
Amycus and his sister were, most likely, among the Death Eaters that were summoned by Lord Voldemort to the churchyard at Little Hangleton on June 24, 1995, as their absence wasn't noted by Voldemort himself.
Battle of the Astronomy TowerEdit
In the evening of June 30, 1997, Amycus and his sister participated in the assault of Hogwarts Castle, orchestrated by Draco Malfoy, that resulted in the death of Albus Dumbledore. When the Death Eaters arrived at the top of the Astronomy Tower, where Dumbledore was trapped, Amycus tried to make fun of the Headmaster and turned suddently violent when Dumbledore hypothesized that he might not reach his old age. When Severus Snape arrived on the scene, Amycus hurriedly said that Draco was not able to kill Dumbledore and Snape cast the curse that ended the Headmaster's life.
On Snape' sorders, he and his sister quickly left the Tower, panting excitedly. In the corridors below, Amycus duelled Ginny Weasley, sending multiple Cruciatus Curses at her. Harry Potter shot an Impediment Jinx that made him slam into the opposite wall. Amycus and Alecto retreated after Snape with their arms over their heads, under blasts by Minerva McGonagall. As the siblings descended the Marble Staircase, Harry took a shortcut and arrived at the grounds before them.
As the two Death Eaters closed in after him, one of them cast a spell that sent Harry to the ground. Harry hit one of them, who stumbled and fell, tripping up the other, with another Impediment Jinx. The two siblings then ran to the gates and Disapparated beyond the school boundaries.
That summer, the Carrows attended a Death Eater meeting at Malfoy Manor concerning plans to capture or kill Harry Potter and take over the Ministry of Magic.
Appointment at HogwartsEdit
On August 1, 1997, the Death Eaters managed to stage a coup over the Ministry of Magic, thus gaining influence over all wizarding Britain. A month later, on September 1, Amycus and Alecto were made Defense Against the Dark Arts and Muggle Studies, respectively,as well as Deputy Headmasters under newly appointed Headmaster Severus Snape.
The Defense Against the Dark Arts curriculum was changed so that it was now simply "Dark Arts". Amycus had his seventh-years practice the Cruciatus Curse on people who have had won detentions. His syllabus also apparently covered the usage of the Killing Curse and Fiendfyre.
As Deputy Headmasters, the Carrows were put in charge of all punishment. The members of faculty were obliged to report any rule-breaking student to them, although they did not if they could avoid it. Punishments given out by the Carrows included torture, via the Cruciatus Curse, as well as chaining students and corporal punishment in the form of beatings and slashes with knives.
Once the Carrows realised they had no hold over Neville, particularly after the Death Eaters' failed attempt to abduct his grandmother, they planned to kill him or send him to Azkaban. As the Carrows chased him, Neville chose the Room of Requirement as a hideout and the rest of the Dumbledore's Army soon followed his footsteps and moved into the room as the Carrows tried to hunt them down. Dumbledore's Army, led by Neville Longbottom, led the resistance against the Carrows. Amycus made a particularly deep gash in his cheek after he refused to use the Cruciatus Curse on students in detention. The group, now made illicit after the reenactment of the Educational Decree Number Twenty-Four, used to sneak into the corridors at night and put up graffiti on the walls with messages like "Dumbledore's Army, Still Recruiting". Michael Corner was caught releasing a first-year the Carrows had chained up, and was violently tortured.
By the evening of May 1, 1998, news of Harry Potter, Ronald Weasley, and Hermione Granger's break-in of Gringotts Wizarding Bank reached the student body; Terry Boot was beaten up by the Carrows for yelling about it in the Great Hall over dinner.
That same day, as Lord Voldemort became aware that Harry Potter, Ronald Weasley, and Hermione Granger were hunting down and destroying his horcruxes, he instructed Amycus and Alecto that Harry might try to get into the Castle and Ravenclaw Tower. At the Carrows' urgent request Professor Flitwick, Head of Ravenclaw House, let Alecto into the common room, where she stood guard.
His sister was keeping watch when Harry arrived with Luna Lovegood. Alecto immediately touched her Dark Mark, letting Voldemort and all the Death Eaters know that they had got him. Alecto was immediately stunned by Luna, but Amycus demanded Minerva McGonagall to let him into the Tower. Once inside, he saw his unconscious sister but no sign of Harry, as both he and Luna were hidden beneath his Invisibility Cloak. Aware that they were going to feel Voldemort's wrath if they did not hand him Harry, Amycus planned to pass it off on the students, and when Professor McGonagall objected calling Amycus a coward in the process, he spat in her face. This show of disrespect for both human life and McGonagall enraged Harry to the point of disregarding stealth and revealing himself, throwing a Cruciatus Curse at Amycus with such force that he slammed into the wall. Minerva McGonagall used a spell to conjure a net, and the siblings were tied up and hoisted into the air, where were left dangling beneath the ceiling.
Neither Amycus nor his sister fought in the Battle of Hogwarts as both of them were kept tied-up at Ravenclaw Tower. It is likely that after the battle and the end of the Second Wizarding War Amycus was imprisoned in Azkaban for his crimes under [[Kingsley Shacklebolt|Kingsley Shacklebolt's de-corrupted Ministry of Magic.
