In 1839, David Malo sat in a classroom at Lahainaluna School in Lahaina, finishing a manuscript that would preserve everything he knew about traditional Hawaiian life. He was 46, teaching students half his age while completing his own work. Through the window he could see the harbor where whaling ships anchored, bringing more foreigners every season. In the courtyard, students practiced English pronunciation. The wooden gods his teachers had served were ash now, burned on Queen Kaʻahumanu's orders.
He dipped his pen and continued writing in the twelve-letter alphabet missionaries had invented thirteen years earlier. The manuscript spreading across his desk documented knowledge that had always been protected—passed down through years of training under kahuna who decided who was ready to learn. He was taking what belonged to specific lineages and making it available to anyone who could read. Using the tools of the people displacing his culture to save fragments of that culture.
The last kahuna who had trained him was dead. There would be no more students. He kept writing.
Malo had grown up in the court of Kamehameha I, trained as an oral historian and genealogist. He learned the way Hawaiians had always learned—through rigorous apprenticeship under experts, through memorized chants and genealogies, through embodied practice. Knowledge lived in relationships between teachers and students, in ceremonies, in voices. You couldn't separate what you knew from how you learned it, from who taught you, from the protocols that governed when and how that knowledge could be shared.
Then in 1819, King Kamehameha I died. His wives convinced the young Kamehameha II to overthrow the kapu system —the sacred laws governing all Hawaiian life. They ordered temples torn down, wooden gods burned. When Protestant missionaries arrived from the United States in 1820, they found a society that had just destroyed its own religious structure.
By 1823, Malo was learning to read and write from Reverend William Richards. The new Hawaiian alphabet simplified a language of subtle sounds into twelve letters. In 1831, when missionaries established Lahainaluna School, Malo enrolled in the first class—in his late thirties, studying geography and Christian theology alongside teenagers.
He was also watching the knowledge systems collapse. The priests who had maintained temples, the navigators who read stars and currents, the healers who knew which plants cured which ailments—they were dying without successors. Most aliʻi had converted to Christianity. Queen Kaʻahumanu had proclaimed laws against traditional practices:
"Worshipping of idols such as sticks, stones, sharks, dead bones, ancient gods and all untrue gods is prohibited."
So Malo documented everything he could remember from his training—the material world of Hawaiians, their origins and myths, the kapu system, land management practices like Mālama ʻĀina. His fellow student Samuel Kamakau made the same choice. In 1841, they helped form the first Hawaiian Historical Society. As Kamakau explained:
"As the people of Alebione (Albion) had their British history, so the Hawaiians should read their history."
When Malo finished Ka Moʻolelo Hawaiʻi (Hawaiian Antiquities) in 1839, he had created something unprecedented—a comprehensive record of traditional Hawaiian beliefs and practices, written by someone who had lived under the old system. It would be published in Hawaiian newspapers, translated into English in 1898, republished multiple times through the 20th century. Today it remains one of only three early accounts of Hawaiian culture created by people who knew it firsthand.
What he saved, he also transformed beyond recognition.
Take traditional healing knowledge. Kahuna laʻau lapaʻau spent years learning which plants treated which ailments, but that wasn't the knowledge. They learned when to harvest—which moon phase, which time of day, which prayers to offer. How to prepare plants, how much to use for different body types and conditions, which combinations worked and which were dangerous. The spiritual protocols, the relationship with the plants themselves, the genealogies connecting healers to their knowledge. All of it inseparable.
Malo documented the plants and their uses. Someone reading his manuscript got a list of remedies without the years of training that taught you how to use them safely, without the protocols that governed when healing was appropriate, without the relationship to land and plants that made the knowledge alive. Knowledge that had required rigorous apprenticeship became information anyone could access.
Within a generation, people were trying traditional remedies without understanding dosage, timing, or spiritual preparation. Harvesting plants at the wrong times, in the wrong ways. Some remedies worked anyway. Some didn't. Some caused harm. The kahuna system that had regulated this knowledge, that had decided who was ready to practice and who needed more training—gone.
Navigation techniques divorced from years of learning to read currents and stars. Land management practices separated from the cultural understanding of relationship with ʻāina. Religious ceremonies described without the context that made them sacred rather than performance. The information survived. The systems that had created, protected, and transmitted that information—the apprenticeships, the protocols, the relationships, the embodied practice—dissolved.
Malo understood. Though he wrote as a Christian convert, scholars note that his work "closely embodies Hawaiian patterns of thought." He chose what to emphasize carefully, spending the most pages on the kapu system and land relationships, trying to preserve not just practices but the logic behind them. Yet he could only do so using tools—written language, Christian framing, Western organizational structures—that fundamentally altered what he was trying to save.
By the late 19th century, most Hawaiians had converted to Christianity. Traditional religious practices had been largely abandoned. The kahuna who had trained Malo were dead, and there were no successors. Yet his manuscript survived, preserving information about a world that no longer existed.
Watch what's happening now as institutions rush to document traditional environmental knowledge before climate change erases it. Anthropologists record indigenous fire management practices. Climate scientists map traditional weather indicators. Government agencies compile water conservation techniques into databases. Universities study crop diversification strategies developed over generations.
They're creating the same kind of archive Malo created—information divorced from the communities and relationships that created it. Traditional burning practices become "prescribed fire management protocols" in government manuals, stripped of the cultural protocols that governed when and how to burn, removed from the spiritual relationship with land that made the practice meaningful. Seasonal indicators become "phenological data" in scientific databases, losing the generations of observation and relationship that gave those indicators context. Oral histories become "climate adaptation case studies," translated into frameworks that fundamentally change what they mean.
The communities holding this knowledge face Malo's choice. Let it disappear with the elders who hold it, or preserve it using methods that transform it into something else. Document traditional practices knowing that removes them from living systems of transmission and protocol. Share knowledge with outsiders knowing that separates practice from the relationships and worldviews that made it work.
Malo's decision in 1839 shows what's at stake either way. His manuscript saved Hawaiian history. It also marked the moment when that history became something that could be saved—removed from living practice, fixed in text, accessible to outsiders, separated from the systems that had created and protected it.
What survived was information. What died was the world that had made that information wisdom rather than data.
And the communities making adaptation choices today need to understand what preservation can mean. Malo knew when he finished that manuscript in Lahaina, watching the harbor fill with foreign ships, teaching in a language that hadn't existed when he was young. He was choosing what would survive and what wouldn't. Using the tools of displacement to fight displacement. Saving fragments while the living systems that had created them collapsed around him, because those were the only options he had.

Aboriginal fire suppression: British Columbia's 1874 Bush Fire Act made cultural burning illegal and punishable by jail time or death, with similar bans spreading across Australia in the early 1900s, leading to dramatic forest changes and increased wildfire severity.
-
Cook Islander missionary pioneers: Trained at Takamoa Theological Seminary in Rarotonga, Cook Islanders became the primary missionaries extending Christianity throughout the Pacific, traveling to Samoa, New Caledonia, and Vanuatu at huge personal cost with many lost to sickness and death.
-
Hawaiian literacy explosion: After missionaries created the twelve-letter Hawaiian alphabet in 1826, literacy rates among Native Hawaiians reached nearly 95% by the end of the 1830s, with Hawaii having more Hawaiian-language newspapers than any other Pacific island nation by mid-century.
