Notes: This took me about 90 minutes. I wrote most of this from memory so I hope it's okay. Yes, I knew the year he was born of by heart too.
Trivia: He was in the year below Minerva McGonagall at Hogwarts as she was born in 1925.
Lord Voldemort was born Tom Marvolo Riddle on 31st December 1926. His mother died moments after his birth and he was raised in a Muggle Orphanage. During his eleven years there, he realised how special he was. He could make the other children do things, or more accurately, do things to them. He stole things from the other children and kept them as trophies, using his ability to talk to snakes to his advantage.
Then one day, Professor Dumbledore came to visit him. He told him he was a wizard and he wouldn’t have to live in the orphanage any more. Tom jumped at the chance to leave; doing everything he was asked until he was on that train. He, like Harry, couldn’t stay at Hogwarts during the summer and so despised every summer he spent back at the orphanage.
Over the course on the next seven years, Tom Riddle became an exceptional student at Hogwarts School of Witchcraft and Wizardry, but specialising in the Dark Arts. He also became a prefect as well as Head Boy, and in his fifth year, he opened the Chamber of Secrets as Salazar Slytherin’s true heir and set the Basilisk on the Muggleborns of the school. This concluded with the death of the ghost now known as Moaning Myrtle and the expulsion of Rubeus Hagrid.
Because it was then unsafe for Tom to open the Chamber again while he was at school, he created a diary and preserved himself in the pages for another day, another year, when Slytherin’s work could be completed. This turned out to be one of the seven horcruxes Harry Potter would destroy.
Despite his half-blood heritage, Tom was always looking towards perfection and pure blood status. He fashioned himself a new name as he hated his filthy Muggle father’s name. He became Lord Voldemort and knew it would be a name wizards everywhere would one day fear to speak aloud. (The letters in the name "Tom Marvolo Riddle" rearrange to spell "I am Lord Voldemort".)
While he was still at school, Tom selected a close group of friends and allies to be known as his Death Eaters while he himself used Lord Voldemort in secret. He asked Professor Slughorn for advice on Horcruxes and planned to make seven to save himself from the ultimate fate of death.
After Hogwarts, Tom asked the Headmaster of the time, Armando Dippet, if he could take up the post of Defence Against the Dark Arts Position. This was declined as Dippet deemed Tom too young and invited him to try again when he was older.
Tom then set out to find more objects to become his horcruxes. These include; Ravenclaw’s diadem, Hufflepuff’s cup and Slytherin’s ring. During this time, he worked in Borgin and Burke’s shop in Knockturn Alley.
After a few more years had passed, and Albus Dumbledore became Headmaster of Hogwarts, Tom approached him asking for the Defence Against the Dark Arts job once again. He was denied a second time and Voldemort cursed the job so that professors only stayed in that job for one year. But his trip to Hogwarts was not fruitless; this was when he hid the diadem in the Room of Requirement.
During the 1970’s, Lord Voldemort rose to power. He and his Death Eaters killed mercilessly as the Ministry of Magic tried to keep everything under control. But in 1979, Sybill Trelawney predicted the fall of Voldemort to Albus Dumbledore. Half of this was heard by Severus Snape, who then told Voldemort.
Voldemort then went after the Potters as he assumed this is who the prophecy was meaning. The Potters went into hiding but were betrayed by their friend Peter Pettigrew. Voldemort killed James first then gave Lily a chance to step aside. She refused and died trying to save her son. When Voldemort turned his wand on Harry, the curse backfired because of his mother’s love and Voldemort was left as vapour.
Voldemort fled to the Albanian forest, seeking physical form though snakes and waiting for one of his Death Eaters to find him. Then in 1991, Professor Quirrell came to Albania and Voldemort manipulated him to bring him to Hogwarts to find the Philosophers Stone. Voldemort’s face was attached to the back of Quirrell’s head and Quirrell was forced to drink unicorn blood in order to give his master strength and power.
But the search from the stone was halted by Harry Potter and Voldemort was left without a body as Quirrell died from this event. This was Harry’s first meeting with the man who had killed his parents.
In 1992, the diary Tom Riddle had created fell into the hands of Ginny Weasley who helped open the Chamber of Secrets once again. And once again, his progress was impeded by Harry Potter. Harry destroyed the diary and killed the Basilisk, leaving Voldemort without body and with Harry still alive.
In 1994, Voldemort had managed to gain a physical form but was still very weak. He was cared for by Peter Pettigrew and nursed to health by his snake Nagini, also a horcrux. With the help of Bartemius Crouch Jr and the Tri-Wizard Tournament, Voldemort managed to capture Harry Potter, kill Cedric Diggory and restore himself a full body at last. Harry survived this meeting once again, helped by Priori Incantatem. Voldemort then planned for a Second Wizarding War.
In 1995, Voldemort and his Death Eaters set about trying to find the full version of the prophecy that was made in 1979. This was stopped by none other than Harry Potter, his five friends, and several members of the Order of the Phoenix. But Voldemort wasn’t going to give up that easily. It was in this year that he realised the connection between The Boy Who Lived and himself and used it to his advantage, creating visions in Harry’s mind to lure him to the Ministry of Magic.
After the Order arrived however, so did Dumbledore. The two duelled but Voldemort fled once the Minister for Magic arrived and his cover was blown. Because of this, Voldemort started killing in broad daylight and the Dementors sided with him. All the Death Eaters in Azkaban escaped and joined back with their Lord and Voldemort established a base at Malfoy Manor.
In 1996, Draco Malfoy was made a Death Eater and was ordered to kill Albus Dumbledore. This was eventually done by Severus Snape and now even Hogwarts wasn’t safe.
In 1997, Voldemort conquered both the Ministry of Magic, using Pius Thicknesse as his pawn for the Minister, and Hogwarts School of Witchcraft and Wizardry, implanting several Death Eaters in key postions with Severus Snape as Headmaster.
Over the next several months, Voldemort searched for the Elder Wand thinking it would break the Priori Incantatem that he and Harry Potter shared at his re-birth. He tortured and killed the wandmaker Gregorovitch and learnt that it had been stolen by a blond boy whom the wandmaker had no name for. This turned out to be Gellert Grindelwald who was now locked up in his own prison of Nurmengard. Voldemort travelled there but killed Grindelwald, gaining no information.
But Voldemort knew that Dumbledore had defeated Grindelwald, so he journeyed to Dumbledore’s tomb and stole the Elder Wand for himself.
After this, Voldemort is informed that Harry has broken into Gringotts vaults and stolen Hufflepuff’s cup. He then realises that Harry is going after his Horcruxes. He checks the places he had previously hidden them outside of Hogwarts before returning there with his army to wage a final battle.
But the Elder Wand was only working like his old wand used to, so he ordered Nagini to kill Severus Snape, assuming this would restore the mastery to him. This failed as Harry was the master at this point.
Voldemort then called an hour of armistice. Harry would come to him or he would enter the battle himself. Harry, of course, came to him and Voldemort finally cast the Killing Curse upon him. But this only killed the horcrux buried deep in the lightning scar and both wizards were knocked out.
Voldemort wasn’t sure about what had happened and ordered Narcissa Malfoy to check to see if Harry was alive. She said he wasn’t because she wanted to return to Hogwarts to find her son. Hagrid was forced to carry Harry and Neville, thinking the prophecy meant him instead, killed Nagini, the last horcrux.
Infuriated, Voldemort then tried to kill Neville but Harry stood between them under his Invisibility Cloak casting a Shield Charm. This started the second round of the Battle of Hogwarts and after several duels, Harry revealed himself to his enemy.
During this battle, Harry taunted Voldemort with his birth name, telling him the truth about Snape and the Elder Wand. Enraged, Voldemort fired a Killing Curse at Harry but the Elder Wand wouldn’t kill its true master and Harry’s Disarming Charm helped backfire the curse, killing Tom Marvolo Riddle at last.
