There is something almost unreasonably magical about the Land of Oz.

I don’t mean that in a throwaway, greeting-card kind of way. I mean it specifically and literally: the world that L. Frank Baum built across fourteen novels is so richly imagined, so internally consistent, and so overflowing with invention that it genuinely defies easy explanation. How did one man — a man who held dozens of jobs before finding his calling, who went bankrupt more than once, who tried repeatedly to walk away from his greatest creation — manage to build something so enduring that the Library of Congress eventually declared it “America’s greatest and best-loved homegrown fairytale”?

I’ve been sitting with that question for a while now. And the more I dig into the history of these books, the more I think the answer has something to do with the fact that Baum wasn’t just writing fantasy. He was writing his life, his losses, his politics, and his love for children into every page. The magic in Oz isn’t just window dressing. It’s the whole point.

Where It All Began

The Wonderful Wizard of Oz arrived in September 1900, published by the George M. Hill Company with illustrations by Baum’s friend and collaborator W. W. Denslow. The first edition of 10,000 copies sold out before the year ended. By October, the second edition of 15,000 copies was nearly depleted too. Children lost their minds for it, and it’s not hard to understand why.

Baum had set out to write something he called “a modernized fairy tale, in which the wonderment and joy are retained and the heart-aches and nightmares are left out.” That mission statement is almost unbearably sweet when you know the personal history behind it. Dorothy herself was named for Baum’s wife’s infant niece, Dorothy Louise Gage, who died at five months old from a brain condition in 1898. Maud Baum was devastated, and her husband — as writers do — channeled that grief into his fiction, creating a girl named Dorothy and dedicating the book to his wife.

The Scarecrow came from Baum’s childhood nightmares, in which a ragged scarecrow chased him across a field and nearly grabbed him before falling apart. The Tin Woodman came from a window display Baum constructed out of a wash-boiler for a body, stovepipes for arms and legs, and a saucepan for a face. The name “Oz” came from a filing cabinet labeled “O–Z.” The Emerald City was partly inspired by Chicago’s gleaming 1893 World’s Fair. The yellow brick road traces, possibly, to actual yellow-brick paving in Peekskill, New York, where Baum attended military academy.

This is how Baum worked: he assembled worlds from whatever was lying around, from the detritus of a life fully lived. And the result was something that felt not just invented but discovered, as if Oz had always been there, just waiting for the right person to find it.

The Books That Followed

Here’s what I love most about this series: it never stops surprising you.

The 1902 Broadway musical adaptation was such a massive hit that it prompted thousands of children to write letters to Baum demanding a sequel. He admitted he wrote The Marvelous Land of Oz (1904) “grudgingly,” to satisfy popular demand. You would never know it from reading the book. It’s a wildly inventive follow-up that doesn’t even star Dorothy — instead centering on an orphan boy named Tip, who spends the novel running from a cruel witch named Mombi, building a walking pumpkin-headed man named Jack, and eventually discovering that he is in fact Princess Ozma, Oz’s rightful ruler, transformed into a boy by Mombi to hide her identity. The book is funny and propulsive and features a flying machine constructed from two sofas, palm tree leaves, a broom, and some clothesline, which remains one of the most charming pieces of magical engineering in children’s literature.

Ozma of Oz (1907) brings Dorothy back and introduces two of the series’ most beloved recurring characters: Tik-Tok, a clockwork mechanical man who is one of the earliest intelligent automata in all of literature, and Billina, a talking yellow hen who turns out to be absolutely clutch in a crisis. The villain is the Nome King, ruler of an underground kingdom, who has transformed the royal family of a neighboring land into ornaments and dares our heroes to guess which ones they are. If they guess wrong, they also become ornaments. It’s a genuinely tense premise, and Baum plays it beautifully.

By Dorothy and the Wizard in Oz (1908), Baum had moved to California and was processing the memory of the 1906 San Francisco earthquake — so naturally, he started this one with an earthquake that swallows Dorothy, her cousin Zeb, a cab-horse named Jim, and a cat named Eureka into the underground Land of the Mangaboos, a civilization of vegetable people who are not thrilled about the intrusion. From there it’s gargoyles, invisible people, baby dragons, and eventually a very welcome rescue via magic belt. The 1939 film gave us one trip to a magical land. The books keep going deeper, stranger, more inventive with each entry.

The Road to Oz (1909) is essentially Baum throwing a party. Dorothy meets a friendly hobo called the Shaggy Man, a perpetually lost boy named Button-Bright, and Polychrome the Daughter of the Rainbow, who fell off her father’s bow while dancing and got stranded on Earth. They all travel to the Land of Oz in time for Princess Ozma’s birthday celebration, which turns out to be attended by characters from across Baum’s entire body of work, plus Santa Claus. The guest list is a delight. The book was printed on pages of different colors to reflect the different countries the travelers pass through, which is exactly the kind of design flourish that makes you love the physical artifact as much as the story inside it.

A World Worth Living In

What Baum was building, book by book, was a complete world — and the more he built, the more convincing it became.

Oz isn’t just one magical country. It’s one quadrant of a larger realm called Nonestica, which contains dozens of kingdoms, each with its own customs and logic and occasional menace. The Emerald City sits at the center of Oz itself, which is divided into four regions: the Munchkin Country to the east, the Winkie Country to the west, the Gillikin Country to the north, and the Quadling Country to the south, where Glinda the Good Witch holds court. The Nome Kingdom lies underground. The Land of Ev borders Oz on the other side of a deadly desert. Every new book adds another piece to the geography, and somehow it all coheres.

The social organization coheres too. By The Emerald City of Oz (1910), Baum had developed Oz’s internal economy to the point where scholars started reading the books as Utopian texts. Oz doesn’t use money. Nobody goes hungry. Nobody lacks for shelter or care. One reader described it as having an “explicitly socialist economy.” Baum himself wrote, a little sheepishly, that he didn’t suppose such an arrangement would be practical in the real world, but he built it anyway — probably because his mother-in-law was Matilda Joslyn Gage, a prominent women’s rights activist whose ideas about social organization clearly shaped the world Baum created. Ozma is a more competent ruler than any of the kings who surrounded her. Glinda is the most powerful figure in Oz. General Jinjur raises an army of women and briefly conquers the Emerald City. The Marvelous Land of Oz is, at its core, a book about female authority and the legitimacy of women’s leadership, written in 1904.

These books were doing more than most people gave them credit for. And the Library of Congress, to its eternal credit, eventually noticed.

The Man Who Kept Coming Back

Here’s the part of this story that I find genuinely moving: Baum didn’t just love Oz. He needed it, financially, in ways that were sometimes uncomfortable and sometimes humbling.

He tried to end the series after The Emerald City of Oz in 1910 — literally wrote Oz out of contact with the rest of the world within the plot, so no future adventures would be possible. Three years later, financial pressures brought him back with The Patchwork Girl of Oz, which he explained in the prologue by claiming he’d contacted Dorothy via wireless telegraph. (He had not contacted Dorothy via wireless telegraph. His publisher needed a book.) He wrote one per year after that until his death.

The Patchwork Girl of Oz (1913) introduces Scraps, a living rag doll made of patchwork with button eyes and a wild, poetry-spouting personality, who becomes one of the series’ most beloved characters. Tik-Tok of Oz (1914) sends the Shaggy Man on a quest to rescue his brother from the Nome King, with a lackadaisical dragon named Quox serving as the weapon of divine vengeance. The Scarecrow of Oz (1915) — which Baum called his personal favorite of the entire series — takes Cap’n Bill and a little girl named Trot through whirlpools and underground caves to a kingdom called Jinxland, where they help the Scarecrow overthrow a corrupt king and restore a princess whose heart has literally been frozen by a witch. Rinkitink in Oz (1916) is set almost entirely outside of Oz, centering on a prince, a jolly fat king, and a surly talking goat on a quest across island kingdoms — Baum had written most of the book eleven years earlier as a standalone fantasy, and simply attached an Oz ending to it. Somehow it works.

The Lost Princess of Oz (1917) begins with one of the series’ great premises: Ozma has gone missing. So has Glinda’s Book of Records. So have all the magical tools in the Emerald City. Dorothy and the Wizard set out to find them, and the ultimate revelation — that Ozma has been imprisoned inside a golden peach pit, being carried unknowingly in Button-Bright’s jacket pocket — is the kind of absurd, perfect detail that makes Baum’s imagination so irreplaceable.

The Tin Woodman of Oz (1918) goes somewhere genuinely surprising: it follows the Tin Woodman back to find Nimmie Amee, the Munchkin girl he once loved before he became tin and lost his heart. He discovers that Nimmie Amee is now married to Chopfyt — a man the tinsmith Ku-Klip built from the leftover body parts of both the Tin Woodman and the Tin Soldier. It’s bizarre and melancholy and deeply, specifically Oz — a book about the strange aftermath of transformation, and about whether being remade into something better means you owe anything to who you used to be.

The Final Books

Baum died in May 1919. The Magic of Oz was published one month later, and Glinda of Oz came out in 1920. He had written both knowing he was dying, and there’s a completeness to them that feels intentional. The Magic of Oz involves a young Munchkin boy who discovers a magical transformation word and teams up with the exiled Nome King Ruggedo, whose schemes are ultimately undone by a talking goose, the correctly pronounced word “Pyrzqxgl,” and the Water of Oblivion. It sold 26,200 copies in its first year, in no small part because readers were buying it to grieve and to hold on to something.

Glinda of Oz — the last one — sends Dorothy and Ozma to stop a war between two obstinate tribes, gets them both trapped underwater in a submerged glass city, and requires Glinda to assemble a rescue coalition of magicians and friends. It’s a book about the difficulty of peace-making and the importance of showing up for the people you love, and Baum dedicated it to his son. As endings go, it’s not a tidy bow. It’s something better: an Oz that’s still in motion, still full of people trying to do right by each other.

After his death, his publishers hired Ruth Plumly Thompson to continue the series, and she wrote twenty-one more books. An original Oz book was published every Christmas from 1913 to 1942. By 1956, five million copies of the Oz books had been published in English alone, with hundreds of thousands more in eight foreign languages.

Why It Still Matters

The 1939 film is a masterpiece. I want to be clear about that. Judy Garland and those ruby slippers and “Somewhere Over the Rainbow” are stitched into the fabric of American culture in ways that don’t need defending.

But the books are their own thing — stranger and bigger and more politically alive than the film suggests. They’re books that imagined a world without money, with female rulers and feminist politics baked into the mythology, with automata and detachable heads and underground kingdoms and flying sofas, with a creator who kept losing everything and kept building back. The silver slippers in the original book — changed to ruby for Technicolor — feel like the right metaphor: the film is gorgeous and transformative, but the original text has something more quietly radical in it, something that doesn’t need to dazzle you with color because it’s already doing something more interesting.

Baum said he set out to write a story that kept the wonderment and joy and left out the heartaches and nightmares. He succeeded at the wonderment. But the heartaches are in there too, if you know where to look — in Dorothy’s name, in the Tin Woodman’s lost love, in a dying man writing one more book for the children who had followed him down the yellow brick road for two decades.

That’s what makes Oz feel true. Not the magic, exactly — though the magic is wonderful. It’s the person behind the curtain, doing the best he could with what he had, building a world worth believing in.

There’s no place like home. But Oz is a pretty remarkable second option.
