Ernesto "Che" Guevara wrote The Motorcycle Diaries, but the book came from his travel journals, not from him as an author

Ernesto Guevara de la Serna — later known as Che Guevara — kept a diary during a 1952 motorcycle journey across South America with his friend Alberto Granado. He did not write the book as a finished work. Instead, decades later, his daughter Aleida Guevara and Cuban editor Giangiacomo Feltrinelli assembled his scattered journal entries, letters, and notes into the published book The Motorcycle Diaries, which appeared in Spanish in 1993 and in English in 2003.

The confusion matters because the book reads like a memoir, but Guevara never intended it for publication. He was 23 years old during the trip and wrote for himself — recording what he saw, felt, and thought as he traveled through Venezuela, Colombia, Ecuador, Peru, and Chile. The entries are raw and unpolished, which is part of why readers find them compelling. You are reading a young man's actual observations, not a carefully constructed narrative written years later with hindsight.

Key Takeaways

  • Ernesto Guevara wrote the original journal entries during a 1952 motorcycle trip across South America, but he never prepared them for publication.
  • His daughter Aleida Guevara and Italian publisher Giangiacomo Feltrinelli edited and arranged the scattered journals into the book published in 1993.
  • The book became widely read after a 2004 film adaptation brought it to international audiences, even though Guevara died in 1967.
  • The diary entries show Guevara's early observations about poverty and inequality in Latin America, which shaped his later political views.

Why the journey happened and what Guevara was doing at the time

Guevara was a medical student in Buenos Aires when he and Granado, a biochemist, decided to take a motorcycle trip to see South America. The journey was partly adventure, partly a way to escape routine. Guevara had asthma and was not expected to survive long, so the trip held a sense of urgency — a chance to see the world while he could.

At this point in his life, Guevara had no political role and was not yet famous. He was a curious, observant young man traveling on a motorcycle called "La Poderosa" (The Powerful One), which frequently broke down. The trip lasted about nine months and covered roughly 8,000 kilometers. During it, Guevara encountered poverty, disease, and inequality that he had not witnessed in his middle-class Buenos Aires life. These encounters shaped how he thought about the world, though he did not yet know he would become a revolutionary.

How the journals became a published book

After Guevara's execution in Bolivia in 1967, his personal papers remained scattered. His daughter Aleida Guevara, who was born after the trip, found his journal entries and other writings. She worked with Giangiacomo Feltrinelli, an Italian publisher and political figure, to organize the material into a coherent narrative. Feltrinelli had connections to Guevara's widow and access to the family's documents.

The Spanish edition came out in 1993, published by Feltrinelli's company. The English translation followed in 2003. Neither Guevara nor anyone close to him during his lifetime prepared the book — it was a posthumous assembly of fragments. This means the book's structure, the order of entries, and even some editorial choices were made by people working from Guevara's notes rather than from his finished manuscript.

The book's impact and why it reached a global audience

The Motorcycle Diaries remained relatively unknown outside Latin America until 2004, when director Walter Salles released a film adaptation starring Gael García Bernal as the young Guevara. The film won awards at international festivals and introduced the story to millions of viewers who had never heard of the book. After the film's success, the book's sales increased dramatically in English-speaking countries.

The book appeals to readers for different reasons. Some see it as a coming-of-age story about a young man discovering the world. Others read it as an origin story for a revolutionary, tracing the moment when Guevara began to understand inequality and injustice. Still others approach it as a travel narrative — a record of 1950s South America told by someone who was there. The book's power comes partly from its honesty: Guevara was not trying to make himself look heroic or to prove a political point. He was straightforward writing what he observed.

What the diary reveals about Guevara's thinking before he became famous

The journal entries show Guevara's growing awareness of social problems, but they do not show him as a fully formed revolutionary. He was still a medical student thinking like a doctor — concerned with disease, poverty, and how to help people. He was also still figuring out his own beliefs. The entries contain contradictions: moments of idealism mixed with casual observations that reflect the prejudices of his time and class.

Readers often project their own views onto the young Guevara in the diary. Some see the seeds of his later communism; others see a thoughtful young man who might have become something entirely different if history had taken a different path. The book does not settle the question because Guevara himself had not settled it. He was 23, traveling, learning, and writing for himself alone.

The difference between the diary and Guevara's later writings

After the motorcycle trip, Guevara went on to play a major role in the Cuban Revolution and to write political manifestos and speeches. Those later writings were deliberate, argumentative, and designed to persuade. The Motorcycle Diaries is different — it is personal, when ready, and exploratory. If you read both, you can see how his thinking developed, but you should not assume the diary predicts his later choices. Many people change their minds; Guevara's change was more dramatic than most.

The diary also contains details about his relationships, his health struggles, his sense of humor, and his doubts — things he would not have included in a political document. This is why the book feels intimate even to readers who know nothing about Guevara's later life. You are reading someone's private thoughts, not a public statement.

How to approach the book as a historical document

The Motorcycle Diaries is useful for understanding 1950s South America and for seeing how one young person experienced poverty and inequality. It is also useful for understanding Guevara as a person rather than as a symbol or a political figure. However, it is important to remember that it is a partial record — Guevara wrote what interested him, and his daughter and publisher chose which entries to include and in what order.

The book is not a complete account of the trip, and it is not a work of journalism or history. It is a personal diary assembled into a narrative decades after the events. If you are reading it to understand Latin American history or to understand Guevara's political development, you will benefit from reading other sources alongside it — historical accounts of the countries he visited, biographies of Guevara, and analyses of the political movements he later joined.

Frequently Asked Questions

Did Guevara write the book himself?

Guevara wrote the original journal entries during the 1952 trip, but he did not write them as a book. His daughter Aleida Guevara and publisher Giangiacomo Feltrinelli organized the scattered entries into the published version in 1993, decades after Guevara's death in 1967.

Is the book accurate to what actually happened on the trip?

The individual entries are Guevara's own observations, so they reflect what he saw and thought. However, the book's structure and selection of entries were decided by the editors. Some entries may have been left out, and the order may not match the exact sequence of events. It is a genuine historical document, but not a complete one.

Why did it take so long for the book to be published?

Guevara never prepared the journals for publication, and after his death in 1967, his papers were scattered among family members and archives. His daughter and the publisher had to locate, organize, and verify the entries before they could be assembled into a book. The process took decades.

Does the book explain why Guevara became a revolutionary?

The diary shows his growing awareness of poverty and inequality, which influenced his thinking. However, it does not fully explain his later political choices. The book captures a moment in his life, not a complete origin story. Other factors and experiences after the trip shaped his path.

Is the 2004 film based directly on the book?

Yes, the film adaptation by Walter Salles uses the book as its source material. However, the film makes its own choices about which scenes to include and how to portray events. The book and film are related but not identical — each tells the story in its own way.
