Part 1: Prewar

Four billion years ago: On Earth-One, the Guardians of the Universe gather most of their universe's magical energy into a mass called the Starheart, which they bury in the heart of a star.

The Super DC Calendar 1976 lists Bruce Wayne’s birthday as February 19 (affirmed in Batman Family #11, May/June 1977) as the birthday of the Earth-One Batman. America vs. the JSA #1 (Jan. 1985)

Legend tells that before that birthday, the neighboring company of Agolea declared war on Bahdnisia and kidnapped Johnny, who is lost at sea and eventually returned to his parents.

8 March 1918: Giovanni "John" Zatara is born. His mother gave him his first magic set for his 15th birthday (1933). Note: Date from the Super DC Calendar 1976. The Digest story says he cast his first real magical spell about two months after he discovered the copies of Da Vinci’s notebooks in a NYC bookstore, which was in November, three months after his professional debut. Since he was already active as a crimefighter in Action Comics #1, and History of the DC Universe says he debuted in 1938, that would mean he found the notebooks in November 1937, putting his birthdate in 1918. DC Special Blue Ribbon Digest #5 (Nov./Dec. 1980)
20 January 1920: Germany is forced to sign the Treaty of Versailles, limiting the size of its military and requiring the payment of massive reparations to the Allied powers. Reparations payments eventually lead to the near-bankruptcy of Germany, setting the stage for the rise of National Socialism.
1920: Archaeologist Sven Nelson is killed after accidentally awakening Nabu in Mesopotamia. Nabu takes Sven's 12-year-old son Kent as his pupil, training him in the ways of magic. NOTE: This was the date in the Golden Age version of Dr Fate's origin. 1st Issue Special #9 (Dec. 1975) later retconned the story to make it later and established that Nabu had magically aged Kent Nelson to adulthood in a few days. The recap of Fate's origin in All-Star Squadron #47 (and Who's Who) returned to the original. The 1975 story can probably be considered apocryphal so far as pre-Crisis continuity is concerned, although it became very important to the post-Crisis version. More Fun Comics #67 (May 1941), 1st Issue Special #9 (Dec. 1975), All-Star Squadron #47 (July 1985)

The Chinese lantern carved from the Starheart finds its way to Arkham Asylum, outside Gotham City, where an inmate named Billings fashions it into a modern railway lantern. The lantern flames green a second time, fulfilling the second part of its mysterious prophecy by restoring the man's sanity and allowing him to return to normal life. NOTES: The original story does not specify the date or that the lantern ended up in Arkham (just "an asylum for the insane"), but it's reasonable to assume that these post-Crisis details also applied to Earth-Two. According to Secret Origins #18, the lantern was brought to America by three adventurers; the art makes it clear that they were Pat Ryan, Terry Lee, and Connie of Milt Caniff's classic newspaper adventure strip Terry and the Pirates, which began in 1934. All-American Comics #16 (July 1940), Secret Origins #18 (Sept. 1987)

NOTES: Early Golden Age Sandman stories strongly implied that Wes Dodds invented the gas gun and its knockout gas. Secret Origins #7 (Oct. 1986)
The Sandman rescues actress Vivian Dale from a ruthless masked kidnapper called the Tarantula. NOTES: Although this was the second Sandman story to be published (several weeks after his textual debut in New York World’s Fair Comics #1, published on April 30), it was probably written first.

22 November 1940: The Justice Society of America (first appearance in print) holds its first official meeting in Gotham City. Members present are the Atom, Doctor Fate, the Flash, Green Lantern, Hawkman, Hourman, the Sandman, and the Spectre. Johnny Thunder and the Red Tornado make brief appearances, although the Tornado flees after accidentally tearing out the seat of her pants. Superman and Batman are mentioned as honorary members. NOTES: Until the end of the war the unofficial real-world rule for JSA membership was that any character with his or her own title left the team to become an honorary member. Superman and Batman were honorary members from the outset because they already had their own books and because most of the characters in All-Star were published by All-American Comics, a separate company owned by DC. Although All-American books carried the DC logo, they were produced through separate editorial offices until the two companies fully merged in 1945.
