The year was 1300 AD, and the Italian city of Bologna was grey with mist and thick with the scent of parchment. In a candlelit study, a young law student named Pietro rubbed his tired eyes. He was staring at a massive, yellowed tome—the Corpus Juris Civilis.
"It is a relic, Pietro," his friend laughed, clapping him on the shoulder. "Why study the laws of an emperor who has been dead for eight centuries? The Roman Empire is dust. We live in a world of feudal lords, local customs, and church canons. Justinian’s law is a corpse. Let it rest."
Pietro nodded, but his heart disagreed. He looked at the dense Latin text. It wasn't just a rulebook; it was a system of logic so perfect it seemed carved from marble, not written on paper. He closed his eyes and listened to his professor, a man who spoke of "Glossators" and the recovery of ancient wisdom.
"Students," the professor intoned, "do not think of this law as a dead stone. Think of it as a seed buried in the earth. It slept through the Dark Ages, but now, it is sprouting."
This moment, centuries ago, was the birth of the phenomenon that the great Mexican jurist Guillermo Floris Margadant would later call La Segunda Vida—The Second Life.
Margadant, looking back from the 20th century with the eye of a historian, saw the story of Roman Law not as a single line, but as a great circle. In his work, he narrated how Roman Law died with the fall of the Western Empire, fragmented into barbarian customs, and was seemingly lost to time.
But then, the "resurrection" began.
In the story of the law, Pietro represented the First Resurrection. This was the intellectual boom in medieval universities. Scholars like Irnerius and later Accursius didn't just read the old texts; they breathed new life into them. They took the Roman rules about dominium (absolute ownership) and applied them to the chaotic feudal lands of Europe. Suddenly, a law written for Roman citizens became the skeleton upon which the modern European states were built. The corpse had opened its eyes.
But Margadant’s story doesn't stop in the Middle Ages.
Centuries later, the "Second Life" took a daring turn. It was the age of colonization. The Roman Law, having matured in Europe, packed its bags and traveled.
Imagine a courtroom in Mexico City in the late 19th century. A lawyer stands before a judge, arguing a property dispute. He does not cite the Aztec tlamatinime, nor does he rely solely on the Spanish Siete Partidas. He cites a principle from the Digest of Justinian regarding possessio (possession).
This was the genius of Margadant’s observation. He saw that Roman Law had accomplished a feat no other legal system had ever achieved: it had transcended its geography. It was born on the shores of the Mediterranean, yet it became the law of the Germans, the French, the Spanish, and eventually, the Latin Americans.
In his book, Margadant acts as a narrator guiding us through this odyssey. He explains that the "Second Life" is the journey of Roman Law from being a specific national law of a fallen empire to becoming the "common law" (ius commune) of the civilized world. The year was 1300 AD, and the Italian
It lived a second life in the Napoleonic Code, which marched across Europe. It lived a second life in the German Bürgerliches Gesetzbuch (BGB), a masterpiece of legal precision. It lived a second life in the codes of Latin America, brought over by Spain and refined by jurists like Margadant himself, who taught generations of Mexican lawyers to see the logic of Rome in their modern Civil Code.
The story concludes not with an ending, but with a realization.
When the student in Bologna turned the page of the Corpus Juris Civilis, he thought he was looking at a fossil. But Floris Margadant, writing in his office in Mexico City centuries later, knew the truth.
He knew that Roman Law was a "zombie" in the best sense of the word—a spirit that refused to die because it was built on the unchanging nature of human conflict and commerce. Buying
In La segunda vida del derecho romano (The Second Life of Roman Law), Guillermo Floris Margadant offers a brilliant and meticulous exploration of how a legal system from antiquity managed to survive the fall of the empire and shape the modern world. Rather than focusing on the "first life" of Roman law—its development in the city-state and the empire—Margadant focuses on its afterlife: the reception, transformation, and ultimate dominance of Roman legal thought in Western Europe and Latin America. The Core Thesis
Margadant argues that Roman law did not die with Rome; instead, it underwent a process of "renaissance" and adaptation. He tracks the journey from the Corpus Iuris Civilis of Justinian through the medieval glossators and commentators, eventually leading to the great codifications of the 19th century, such as the Napoleonic Code. His central premise is that our current civil law tradition is essentially Roman law filtered through centuries of scholarly interpretation. Critical Strengths
Narrative Clarity: Margadant has a rare ability to take dense, technical legal history and turn it into a compelling narrative. He explains the "why" behind legal shifts, making the book accessible to students and seasoned jurists alike.
Historical Context: The author does not view law in a vacuum. He brilliantly connects legal changes to the political, social, and economic pressures of different eras, such as the rise of the universities in Bologna or the needs of the emerging merchant class.
The Latin American Perspective: As a legendary figure in Mexican legal education, Margadant provides invaluable insights into how this European tradition crossed the Atlantic to become the bedrock of Latin American legal systems. Final Verdict
La segunda vida del derecho romano is more than just a history book; it is a fundamental map for understanding the genetic code of modern civil law. It is essential reading for anyone who wants to understand why we think about property, contracts, and obligations the way we do today. Margadant proves that Roman law is not a dusty relic of the past, but a living, breathing foundation that continues to govern our daily lives.

La obra "La segunda vida del derecho romano" de Guillermo Floris Margadant es un texto fundamental para comprender cómo un sistema jurídico de la antigüedad logró trascender su propia caída política para convertirse en el cimiento de la cultura legal de Occidente. Margadant, jurista emérito de la UNAM, no se limita a un análisis técnico, sino que narra la "supervivencia" del derecho romano como un fenómeno histórico vivo y en constante evolución. ¿Qué es la "segunda vida" del derecho romano?
El concepto de "segunda vida" (término acuñado originalmente por Paul Vinogradoff y popularizado en el mundo hispano por Margadant) se refiere al periodo en el que el derecho romano dejó de ser la ley vigente de un imperio para transformarse en una autoridad intelectual y científica en Europa. Según Margadant, esta etapa tiene hitos temporales claros:
Punto de partida (Dies a quo): Se sitúa a finales del siglo XI con el "redescubrimiento" del Digesto de Justiniano en Italia, lo que dio origen a la Escuela de los Glosadores en Bolonia.
Punto final (Dies ad quem): Termina cuando el derecho romano deja de ser derecho supletorio o vigente para ser reemplazado por las modernas codificaciones nacionales (como el Código Napoleónico de 1804 o el Código Civil Alemán de 1900). Estructura y temas clave del libro
A través de sus más de 400 páginas, Margadant detalla el recorrido del Ius Commune a través de diferentes escuelas y geografías: Derecho Romano Guillermo Floris Margadant
"Roman law did not die with Rome; it merely changed its clothes to survive the centuries." "The Glossators gave Europe a common legal language,
"The Glossators gave Europe a common legal language, and the Commentators gave it practical solutions."
"The French Civil Code is the most successful popularization of Roman law, but the German BGB is its most scientific expression."
"In Mexico, Roman law lives not in museums but in the daily work of judges and notaries."
Cuando la mayoría de los manuales hablan de la "decadencia" del Derecho Romano tras la caída del Imperio de Occidente (476 d.C.), Margadant cambia el enfoque. Para él, la primera vida del Derecho Romano abarca desde la Ley de las XII Tablas (451 a.C.) hasta la muerte de Justiniano (565 d.C.), donde se compila el Corpus Iuris Civilis.
Pero el imperio no cayó por completo; se transformó. La "segunda vida" comienza precisamente en la Edad Media y se extiende hasta nuestros días. No es una resurrección milagrosa, sino una recepción continua.
Margadant identifica varias fases de esta segunda vida:
Un estudiante de derecho puede sentirse tentado a saltarse la materia de Derecho Romano, considerándola un requisito arcaico. La obra de Guillermo Floris Margadant es el antídoto perfecto contra esa pereza intelectual.
Leer a Margadant es recibir tres lecciones fundamentales:
Antes de sumergirnos en la "segunda vida", es vital entender al autor. Guillermo Floris Margadant (1924-2011) fue un jurista, historiador y romanista que, nacido en los Países Bajos, encontró en México su patria intelectual. Formado en la tradición romanista europea (la más pura), se enfrentó a un desafío: enseñar Derecho Romano a estudiantes mexicanos que veían a Justiniano como un personaje más lejano que Moctezuma.
Su genialidad fue demostrar que el Derecho Romano no era la historia de una civilización muerta, sino el software jurídico que aún operaba bajo el hardware de los códigos modernos. Su libro, simplemente titulado El Derecho Romano, es la obra de derecho romano en español más consultada en América Latina. En sus páginas, Margadant no solo explica las Instituciones de Gayo o el Digesto, sino que constantemente traza líneas directas entre la actio romana y la demanda contemporánea, o entre el dominium y la propiedad del Código Civil.
¿Qué es una condición, un término o un modo? Son modalidades del acto jurídico que los romanos inventaron para manejar la incertidumbre. La distinción entre condición suspensiva y resolutoria fue elaborada por juristas como Marcelo y Papiniano, y Margadant demuestra que los redactores del Código Civil mexicano de 1928 la copiaron casi textualmente del derecho justinianeo.
