Birth of Nicholas Fury in New York, New York to American fighter pilot Jack Fury and his wife in 1914. Logan will have numerous encounters with Fury.

Birth of Eugene Judd in Saskatoon, Saskatchewan in 1914 (Alpha Flight #32). Logan will have numerous encounters with Judd as well, who will eventually adopt the identity of Puck.

Venturing into the eastern Rockies, Logan obtains work for the Hudson Bay Company, a British corporation (Marvel Comics Presents #93-98). Among his co-workers are Crawlface Bob and Du Bois, both of whom are killed by Blackfoot Indians. Venturing into Blackfoot territory himself, Logan encounters the demonic creature known as Uncegila.

Uncegila is a monstrous worm that spread disease and corruption as it traveled underground, and who could kill with a single glance, the creature known only as Uncegila threatened the Blackfoot Indian tribe in the 1840's.

Wolverine had been taken in by the tribe to heal after killing the spawn of Uncegila - a monstrous bear that had been corrupted by Uncegila's touch. In the months that Wolverine spent with the tribe, he grew enamoured of Sparrow Hawk.

Soon after, Uncegila attacked, crippling the young native named He Counts Horses and devouring Sparrow Hawk, the lover of Wolverine.

Wolverine tracked the creature down, and with the help of a young blind Indian boy, he slew the monstrous worm and cut out its heart. Over a century later, Wolverine returned to the Eastern Rockies on the U.S./Canadian border and discovered the cave in which the creature's bones still lay.

At this time, Logan is already using as personal weapons two steel knives, "Spanish-made and Mexican-forged." He claims to have received them as a gift from "a little gambler from Natchez," whom he evidently encountered either in the frontier town or while working for the Hudson Bay Company. They are the first of many bladed weapons that Logan will wield throughout his long life. The Blackfoot, impressed by Logan's battle prowess, name him "Skunk-Bear," or "Wolverine"; Logan takes a liking to the name, but, as far as is known, he will not use it again for decades.

These events, Logan's first known encounter with the supernatural, eventually prove so troubling to him that he suppresses them from his conscious memory, unless his inability to recall them can be traced to his time with Team X. Decades later, he will recall them in a dream, which his subconscious sets during the 1840s, although the possibility that these events in fact happened not to Logan but to an earlier incarnation of his soul cannot be dismissed.

Logan travels into more populated areas of Canada, eventually joining the Army. Still a part of the British Empire, Canada's armed forces become involved in World War I. He is assigned to a special unit of the Canadian military known as the Devil's Brigade (Alpha Flight #33). It may be during this period that he first becomes familiar with the uses of explosives and the Fairbourne dagger (Wolverine #106). Logan's commanding officer is a superhumanly-strong man known only as Cyber (Marvel Comics Presents #88), whom Logan will later recall as "someone I looked up to in my misbegotten youth." Although a severe disciplinarian who strikes Logan on some occasions, Cyber still commands respect as one of Logan's first teachers. In this new life, Logan again begins to find love, as he romances a young woman named Janet (Marvel Comics Presents #134).

It is possible that he meets American author Ernest Hemingway (Wolverine #35), an American correspondent during the war, during this period. Still troubled by his encounter with Uncegila, Logan seeks solace in Christianity (Uncanny X-Men #164); he will later pronounce this effort to be "a mistake." According to one account, at some point during World War I, Logan encounters a German agent named Eikert (WildCATs/X-Men: The Golden Age.). Logan and Eikert will meet again decades later, during World War II.

Under circumstances and for reasons which have yet to be revealed, Cyber murders Janet (Marvel Comics Presents #134); Logan does not learn of this until after a battle engagement with the Devil's Brigade. When confronted, Cyber, beside whom Logan had fought so recently, brutally beats Logan and gouges out one of his eyes, presumably for daring to confront a superior officer in such a manner (Marvel Comics Presents #85-92). Logan's Christian faith does not survive the death of Janet and this experience with Cyber. His injury at Cyber's hands is the most severe wound that Logan has suffered up to this time.

It will be months before his mutant healing factor regenerates his lost eye; however, still unaware that he is a mutant (Alpha Flight #33), Logan simply assumes that his eye, although severely damaged, was not in fact removed. It will be decades before he realizes the true nature of his healing abilities. Presumably, he wears a patch over his eye until it heals. It may be during this period that he first uses the alias "Patch," a name he will periodically use for the rest of his life. Still a young man, Logan is so shaken by these events that he blocks much of them from his conscious memory, remembering only that he suffered this severe wound "in the war---with the Devil's Brigade"; the experience continues to haunt his dreams for decades until, finally, he confronts Cyber once more and removes one of Cyber's own eyes in repayment.

Birth of Steve Rogers in New York, New York to Joseph and Sarah Rogers in 1922 (Captain America Annual #10). Logan will have numerous encounters with Rogers as well, after Rogers takes the identity of Captain America.

In the later years either of or directly after World War I, Logan leaves the army. Taking passage aboard a ship, travels to China (Marvel Comics Presents #41/113), where he meets Chang, a Chinese businessman with whom he shares undisclosed adventures. Although Logan does not realize it at the time, Chang is an employee of the agency known as Landau, Luckman, and Lake (Logan: Path of the Warlord). Logan will later become very familiar with them. In later years, Landau, Luckman, and Lake will expand into interdimensional operations, eventually having operatives on many alien worlds, but the precise nature of their activities during this period is unclear.

It will be many years before Chang feels that Logan is suitably prepared to learn the truth about his employers' activities. At one point, Logan and Chang are photographed on nineteenth century tintype at a shipyard (Wolverine #5). Whether the use of this medium should be taken to indicate that the pair had traveled back in time is open to debate.

In Shanghai, Logan first makes the acquaintance of Ogun (Wolverine #113), a Japanese samurai and sorcerer whom some claim to be immortal (Kitty Pryde and Wolverine #4). Logan prevented soldiers under Ogun from assaulting a Chinese mystic and his young westerner pupil, noting that "you don't make war on old men and children". Logan's comment in this instance may be indicative of some of his experiences with the Devil's Brigade. Ogun, at this time a Captain in the Japanese Imperial Army, is impressed by Logan and offers to instruct him in the martial arts at the Ogun Ryu Dojo in Kanazawa, Japan. Meanwhile, anunnamed mystic, similarly recognizing Logan's potential, offers to instruct him in "plumbing the mysteries of the universe." Logan, determined to avoid responsibility after his disastrous stint with the Devil's Brigade, declines both offers, claiming that he has "places to see and things to do."

It may also be in China at this time that Logan meets Adam Destine (X-Men/Clan Destine #2) - a man granted indestructibility and immortality centuries ago. (Adam Destine was around in 1612 to help establish the Romanov dynasty in Russia.)

So far, Logan does not realize that he himself, to some extent, shares these qualities with Destine. Logan and Destine develop a great respect for each other and share at least one adventure, which culminates in the bombing of a mountain fortress by someone named Chen Yu. Destine believes Logan to have been killed in the explosion and departs the area, but Logan survives and recovers from his wounds; it will be decades before the two meet again. It is possible that Ogun and Destine are the first centuries-old individuals that Logan has encountered; they will not be the last.

Although details are vague, it may be during this period that Logan first encounters two centuries-old sorcerers, the benevolent Gomurr the Ancient (Uncanny X-Men #329-330) and the malevolent Mister Jip (Uncanny X-Men Annual #13). Gomurr will later comment that Logan has never known how to "respect [his] elders." Yet, Jip will recall Logan as "impetuous"; Logan and Gomurr will meet again years later, after Logan has become skilled in the art of the samurai, while he will encounter Jip as part of an adventure with the X-Men.

It may also be during this time that Logan first meets a man called Black Crane (Uncanny X-Men #363); decades later, Logan will speculate that Black Crane might be a mutant, because he has seen Black Crane do some remarkable things.

According to one account, Logan will later express familiarity with the Cult of Si-Fan (WildCATs/X-Men: The Golden Age), servants of the notorious criminal Fu Manchu, and it may be during this period that he first encounters the Si-Fan and other strange secret societies.

During his Chinese exploits, Logan adopts a carefree, irreverent attitude, but his past sufferings and his various encounters with the supernatural and other unexplained phenomena tear at his veneer of humanity; feeling himself the pawn of forces he does not understand, he eventually assumes a "predator" persona (Wolverine '96 Annual) to intimidate those around him. Logan will later categorize his activities during this period as an effort "to run...an'fight his way beyond the pain," claiming that he "fought his way clear 'cross the world."

Birth of Erik Magnus Lehnsherr outside of the free city of Danzig, Poland (X-Men Unlimited #2) in 1928.

Birth of Jessica Drew in London, England to Jonathan and Merriem Drew, also in 1928.

After an indeterminate number of years, during which he may or may not have ventured out of Asia, Logan's travels lead him to the island nation of Madripoor (Uncanny X-Men #268, Wolverine #126-127, where he meets a woman known only as Seraph, proprietor of the Princess Bar. Seraph, unimpressed with Logan's attitude, takes him under her wing and helps him deal with the tragedies that life has dealt him thus far; through his friendship with her, Logan learns lessons about responsibility, morality, and grace. Logan will later credit Seraph with giving him "free will."

Logan makes many other friends on Madripoor, most notably the prostitute Madame Joy (Wolverine #10), and will eventually become part-owner of the Princess Bar.

Logan learns that Seraph has appointed herself the guardian of Madripoor against the Hand, an ancient order of classically-trained ninjas who are feared throughout the Far East. They are also familiar with modern weaponry, although they tend not to utilise it. The Hand is led by a number of jonin (masters), to whom loyalty and life are pledged. The Hand has come into contact with Wolverine many times, all to their regret. The Hand strives for power, and will use political maneuvering as well as subtle and deadly force to achieve it. The genin also have the ability to turn their bodies to mist when they are killed, thus preventing interrogation.

Logan develops a deep devotion to Seraph, and he will fight by her side a number of times over the decades; like Logan, Seraph seems to age little if at all during this period, but the secret of her apparent immortality has yet to be revealed. Logan, still using the alias "Patch," develops a notable reputation in Madripoor which will linger for decades to come; news clippings of Patch's Madripoorian exploits remain in his possession to this day (Wolverine #79).

Driven to reshape his spirit in order to better assist Seraph, yet unable to shake his bestial side alone, Logan remembers Ogun's offer and travels to Japan for the first time (Uncanny X-Men #118; Kitty Pryde and Wolverine #3); still "a punk kid" when he makes this journey, Logan will eventually come to regard Japan as his second home (Uncanny X-Men #162). Logan spends years studying under Ogun, whose skill in swordsmanship may have rivalled that of any other warrior in his nation's history. Many years later, Logan tells Kitty Pride that "he was my sensei. That man taught me just about everything I knew."

A few weeks after beginning his training, Logan observes a battle between Ogun and a band of ninjas hired by crimelord Ugama Hana, one of Ogun's many enemies (Wolverine #169). After easily defeating the ninjas and battling Hana, Ogun allows Hana to drive a sword into his chest. Despite this seemingly fatal wound, Ogun removes the sword from his own chest and mocks Hana's efforts, decapitating him shortly thereafter. This is the first demonstration of Ogun's true mystic power that Logan witnesses; over the years he will see Ogun cheat apparent death many times.

Even after training Logan, Ogun remained his superior in skill in hand-to-hand combat. Logan also tells Kitty, "I respected him, Kitty. I... loved him like a father. Whatever I am today, a lot of it's because of him."

While in Japan, Logan also takes up diving (Marvel Comics Presents #41), which gives him a sense of peace he has never before achieved.

According to one account, while in Japan at some point in the early 1920s, Logan is instrumental in saving the life of the leader of the Kage Ryu' (Wolverine/Shi: Dark Night of Judgment), or Dragon Clan, a society of mystic warriors who have been locked in a secret war with the rival society known as the Kyoto Sohei since the tenth century; as a result of his heroism, Logan is accepted into the Kage Ryu' and serves as its elite soldier, or Montra Warrior, against an opponent from the Kyoto Sohei, a role in which he succeeds and which he will take up anew every twenty-five years.

Despite his newfound devotion to martial arts, Logan's wanderlust proves too great a temptation, and he does not complete his samurai training at this time, instead, it would seem, traveling periodically throughout Asia and Europe, apparently using Japan as a home base.

Little is known of these adventures, but it is possible that, at some point during these years, Logan works alongside Irene Adler and "Mr. Raven," an identity which may be an alias of the shapechanging Raven Darkholme; decades later, Adler and Darkholme, as Destiny and Mystique, will found the second Brotherhood of Evil Mutants and clash with Logan and the X-Men many times.

The precise nature of this work is unknown, but in 1936, on behalf of Adler and Raven, Logan aids the time-traveling American mutants Kitty Pride and Rachel Summers (X-Men: True Friends #2-3), both of whom are Logan's teammates and friends in the X-Men some decades in the future, in their encounter with the ancient entity known as the Shadow King and the German agents Baron Strucker and Geist, all three of whom Logan will clash with in later years. Destiny explains to the past version of Wolverine that Kitty must not kill Hitler nor other prominent Nazis, but frets that they should not interfere with her efforts, while a laconic Mystique says "we all of us have learned to kill, Logan. But more importantly, we have learned not to kill. And to know the difference."

At some point during the mid 1930s, Logan develops a close attachment to the Romanoff family in Russia (Uncanny X-Men #268), particularly young Natasha Romanova, who comes to call him "little uncle." Logan's connection to the Romanoffs remains unrevealed, but it may relate to Romanova's natural aptitude for the martial arts, which will later make her a target of the Hand; it is, in fact, possible that at least some of Logan's activities during this period were part of a search for such gifted children undertaken on behalf of either Seraph or Ogun, although this is only conjecture. Upon reaching adulthood, Romanova will, under circumstances yet to be revealed, be exposed to a process which will retard or arrest her aging process, and she will eventually become the espionage agent known as the Black Widow.

Interestingly, a verified instance of Logan time-traveling from the future occurs less than a year later; during April of 1937 (Wolverine #35-37), the Logan of nearly sixty years in the future arrives in northern Spain, where he encounters, among others, Ernest Hemingway and adventurer Eugene Judd, whom Logan will later know as Puck. Judd had fought in the Spanish Civil War. While there he met and became friends with news correspondent Ernest Hemingway.

A later version of Judd in fact travels back in time with Logan, apparently merging with his past self. As far as is known, the "contemporary" Logan, whose activities at this time are unknown, never learns of this incursion by his future self; it is possible that, during the years of 1936 and 1937, Logan was involved in some set of circumstances, perhaps under the auspices of Landau, Luckman, and Lake, which rendered this period unusually prone to time travel by his future selves, although this is mere conjecture.

Following these events, apparently after Judd has departed the area, Logan himself sees action in the Spanish Civil War (Wolverine #79), although no details of his role in the conflict are available; records of his role in the war remain in Logan's possession to this day.

It will be in two years that Judd discovered the mystical Black Blade of Baghdad and encounters Razor, entraping Razor within his own body. It is ths encounter that caused Judd to be stuck at the height of 3.5 feet tall. (The presence of Razor within his body caused Judd incredible pain, but Razor's mystical energies caused Judd to age incredibly slowly.)

If the archaeologist/adventurer Indiana Jones is in fact a historical figure and not a fictional character, Logan may encounter him during this period; decades later, Logan will be impressed enough by the film "Raiders of the Lost Ark" (Micronauts #37) to watch it at least thirteen times. It is also possible that Logan spends time wandering alone through an unspecified jungle during this period (Marvel Comics Presents #117), although his later references to such adventures may actually refer to Team X-related work in the jungles of Southeast Asia.
