Timeline of the first Voldemort War
This is my timeline for Potterverse events from around the time of Tom Marvolo Riddle's return from his travels to the aftermath of the first Voldemort War. My confidence in the precise timing of events varies. In the past I preferred a timeline where Riddle's return was somewhat later (in the 1960s), which can be accounted for by having Dumbledore teach DADA from December 1956 to Dippet's death or retirement. I still think it is a reasonable interpretation, though I think Rowling meant to have Dumbledore move directly from teaching Transfiguration to the headmastership (making one wonder why he was conducting an interview with someone who wanted the DADA position).
Dec 1956 Armando Dippet dies or retires. Dumbledore headmaster after refusing Minister position for third time. Minerva McGonagall starts teaching Transfiguration. A few of TMR's followers (already known as Death Eaters) await at The Hog's Head as TMR interviews for the DADA position with Albus Dumbledore. TMR hides the diadem in the ROHT and curses the DADA position. Dumbledore recognizes TMR's appearance as sign of unusually Dark Magic and starts researching TMR's past. At this time there are rumors about the Death Eaters but neither Voldemort nor the Death Eaters are wanted for any particular crime. Sep 1959 - Aug 1960 Births of Marauders cohort. (Sirius Black in Sep-Oct?) Lily Evans and Severus Snape in January, James Potter and Remus Lupin in March and Peter Pettigrew? 1961 Regulus Black born (Mid 1960s Remus Lupin bitten by werewolf Fenrir Greyback) TMR starts recruiting heavily among the sons, nephews and sons-in-law of his own schoolmates. The actions of this group are not known at this stage. I believe the scale was rather small, with little political impact. (Late 1960s TMR wanted by Ministry - I think this is the result of Dumbledore's investigation, I think this is when TMR became wanted for the murder of Hepzibah Smith) (Late 1960s or 1970 Arthur Weasley and Molly Prewett elope) c 1970 TMR's name becomes unmentionable by his own circle as well as within Dumbledore's. At this stage the war within the wizarding world consists mainly of: political assassinations of members of Dumbledore's faction; kidnappings by DEs of victims to be killed by Voldemort in order to make them inferi for his cave; marches of DEs, public torture of Muggles (similar to QWC events) Summer 1971 Whomping Willow planted Sep 1971 Marauders cohort starts at Hogwarts. Marauders and Lily Sorted into Gryffindor, Severus Snape is Sorted into Slytherin, where Lucius Malfoy, a 7th year (or possibly a 6th) is Prefect. Nov 1971 Bill Weasley born Sep 1972- Aug 1973 Nymphadora Tonks born c 1973 James Potter, Sirius Black and Peter Pettigrew start improvised training to become Animagi Sep 1972 or 1973 Regulus Black starts at Hogwarts Dec 1973 Charlie Weasley born Sep 1975 Remus Lupin (and Lily Evans?) appointed Prefect(s)) Sep 1975 - spring 1976 Successful Animagi transformations of the Marauders, Levicorpus becomes popular, werewolf caper Jun 1976 the Marauders' cohort sits OWLs, Snape's Worst Memory Jul 1976 Sirius Black leaves home, moves in with the Potters Aug 1976 Percy Weasley born c 1977 Sirius Black inherits gold from his uncle Alphard, moves into his own apartment; sometime later elder Potters die, leave home and much gold to James. Summer 1977 James and Sirius ride enchanted motorbike to escape from 3 pursuers on broomsticks, leaving a couple of confused Muggle policemen in their wake. Sep 1977 James Potter Head Boy, Lily Evans Head Girl (Christmas break?) 1977-8 Regulus Black becomes Death Eater April 1978 Fred and George Weasley born Jun 1978 Marauders' cohort leaves Hogwarts, Marauders and Lily join Order of the Phoenix (Peter Pettigrew only one with day job?), Severus Snape becomes full-time Death Eater (does he have a day job?) (Christmas break?) 1978-9 Kreacher nearly dies in the course of testing TMR's protections for the locket. Several weeks later Regulus Black and Kreacher substitute a fake locket, Regulus dies, Kreacher escapes with locket. c 1979 - a significant increase in DE activity, causing loss of public trust in the Ministry and an extremely low birth-rate. This is when the war starts impacting the bulk of the wizarding world, when Voldemort showed his true face and lost the support of the mainstream purebloods, this is when the DEs started advertising their actions by flying the Dark Mark over the site of an attack. Sep 1979 Hermione Granger born Late 1979 Lily finds she is pregnant, stops active duty (as does Alice?) ? 1980 Millicent Bagnold becomes Minister (Bartemius Crouch Sr becomes head of the Department of Magical Law Enforcement and issues harsh measures against Death Eaters, including permitting the use of Unforgivables by Aurors) Mar 1980 Ron Weasley born Autumn 1979-spring 1980 Sybill Trelawney makes her first prophecy. Severus Snape overhears it and reports to Voldemort. Jun 1980 Draco Malfoy born Jul 1980 Neville Longbottom and Harry Potter born ----------- Some guesswork in this section:
Sep or Oct 1980 Peter Pettigrew is recruited by Voldemort (though probably not yet Marked DE). Autumn 1980 Severus meets with Dumbledore on windswept hill, brings warning of impending attack on Potters. Potters go into hiding. Severus starts spying on DEs. (Alternately Peter's recruitment roughly coincides with Severus' defection - the reason Severus knew of Voldemort's intentions may have been because Voldemort wanted information about James' friends in order to decide whom to recruit as spy.) c Jan-Feb 1981 Moody starts following Karkaroff as a result of a tip-off by Severus. ?? Peter creates distrust between Remus and other Marauders. Spring or summer 1981 On Voldemort's orders Severus applies for DADA job, is appointed as Potions Master instead. Jun 1981 Slughorn retires. Jul 1981 Order photograph taken. Remus no longer part of Marauders. (Peter brings copy to Voldemort?) Dumbledore takes invisibility cloak from James. Attack on McKinnons (by Karkaroff, Travers and others) Karkaroff is arrested Summer - autumn 1981: Other attacks, including Meadows, Fenwick, Prewett brothers and Bones family. DE Rosier is killed by Moody, DEs Dolohov, Travers and Mulciber arrested. (Severus confirms Dumbledore's suspicions that Voldemort has a spy near the Potters? Severus being sent to interview alerts Dumbledore that attack is near? Or perhaps Severus reports date of planned attack? - At any rate, I think Dumbledore may have suggested himself as Secret Keeper as early as the summer if Potters and friends did not know how to cast the Fidelius Charm themselves. In this case Peter reported back to Voldemort who instructed him to become Secret Keeper and frame Sirius. Voldemort decided to delay the attack until Peter became Secret Keeper) Aug 1981 Ginny Weasley born Oct 1981 By this point Dumbledore has made offer of himself as Secret Keeper, was rejected. Late Oct 1981: Dumbledore gives up on becoming Secret Keeper, instead places a warning alarm on their home to alert him (but not them!) of an attack. Potters placed under Fidelius Charm with Peter as Secret Keeper. Voldemort gives diary to Lucius. Oct 31 1981 Voldemort kills James and Lily Potter, becomes vaporized when attempting to kill Harry Potter. A piece of his soul attaches itself to Harry. Hagrid is sent to rescue Harry, meets Sirius, gets bike, takes Harry somewhere to recover. (Dumbledore examines Harry, Hagrid reports destination to McGonagall.) Dumbledore tells Ministry (Crouch Sr?) of Sirius' treachery. Nov 1st 1981 Sirius-Peter confrontation. Sirius arrested, sent to Azkaban. That night Harry is brought by Hagrid to 4PD, placed by Dumbledore at Dursley family's doorstep. Within days, Peter as Scabbers is found by Percy Weasley. Nov 1981 Lucius Malfoy, Avery and many others claim to have been Imperiurized into serving Voldemort. Eventually most are cleared by Wizengamot. Nov-Dec 1981 Karkaroff's hearing. Dec 1981 - Jan 1982 Rookwood arrested and tried. Jan 1982 Caradoc Dearborn disappears. Later in 1982 Bagman tried and cleared. Bellatrix, Rodolphus, Rabastan Lestange and Bartemius Crouch Jr attack Frank and Alice Longbottom. The 4 are arrested, tried and sent to Azkaban. Sep 1983 Bill Weasley starts at Hogwarts. 1983 Crouch Jr escapes Azkaban with the help of his parents. His mother dies in Azkaban, he is placed under the Imperius Curse and kept captive by his father.
