Federico II & His Legacy
Frederick II of Swabia ruled Sicily, southern Italy and the Holy Roman Empire in the 13th century. His university, laws, religious tolerance, diplomacy and castles left a mark that is still visible from Naples and Palermo to Lucera, Melfi and Castel del Monte.
An 800-year university legacy
In 2024 the Federico II University of Naples marked its 800th anniversary. Emperor Frederick II founded the Universitas Neapoletana in 1224 as the first public university in the world. It was not the oldest university, since five institutions predate it, but it was the first to be established, run and paid for by the state. Free higher education for all was a radical idea at the time, and the institution remains one of the most prestigious universities in Europe.
The university was intended to make knowledge available beyond a small elite. Frederick's edict imagined Naples as a place where the arts and every profession would be taught, so people hungry for learning could find it in his kingdom. Children in Naples still receive the name Federico II, a sign of how strongly the ruler remains woven into local memory.
A southern Italian by choice
Frederick was King of Sicily, King of Italy and Holy Roman Emperor. His father was Henry IV of the Swabian Hohenstaufen dynasty, and his mother was Costanza d'Altavilla, the daughter of a Norman king of Sicily. Neither parent was Italian, yet Frederick chose the south as his home. He spent almost all his life there, apart from military expeditions, moving between Sicily and Puglia and adopting the title Puer Apuliae, or child of Apulia, a term that could refer to the whole south.
His attachment to the region became part of his legend. He is remembered as someone who preferred the landscapes of Sicily to an abstract paradise and who regarded an Apulian valley as precious enough to rival anywhere on earth. Writers and historians have alternately portrayed him as a villain, a model ruler, the Antichrist or an almost saintly second coming. The mix of documented achievements and political propaganda makes the historical figure difficult to separate from the myth.
A pioneer with a new political language
Frederick tried to unify his territories through political and economic reforms, as well as through a shared official language. He supported Siciliano Illustre, a literary language created by scholars at his court so that laws and public decisions could be understood more widely. His approach was unusually modern: central government, trained officials, public education and a culture that could include more than one tradition.
A promoter of peace and knowledge
Frederick knew at least six languages: Latin, Greek, Sicilian, German, French and Arabic. Some historians give him a total of nine. He was curious across disciplines, supporting work in astrology, mathematics, medicine, natural sciences and philosophy and paying for experiments that demanded costly equipment or long research.
His Magna Curia, or great court, in Palermo became a meeting place for Greek, Roman, German, Arab and Jewish cultures. Scholars from many regions gathered there, translated works by Aristotle, Averroes and Avicenna, and took part in philosophical and diplomatic conversations with people of different faiths.
Diplomacy in the Crusades
Frederick's friendship with the Ayyubid Sultan al-Malik al-Kamil was genuine and was criticised by his contemporaries. He did not support the pope during the Fifth Crusade and was excommunicated. When he eventually joined the Sixth Crusade to obtain the pope's pardon, his relationship with the sultan enabled a diplomatic victory without a battle. He was crowned King of Jerusalem without bloodshed, which angered the pope further. Arabic records from the period describe a curious, open-minded ruler rather than repeating the hostile European propaganda.
Religious tolerance and Lucera
Frederick allowed Muslims, Jews and people whom Rome had declared heretics to live in his lands and promoted the principle that men should stand equal before the law regardless of religion. After suppressing a Muslim revolt in Sicily in 1223, he did not kill or deport the rebels. Instead, he established a Muslim settlement at Lucera in Apulia, the first settlement of its kind in Italy. Saracen archers also served in his armies, an extraordinary choice when Catholic Europe treated them as sworn enemies. At one point the pope even accused Frederick of secretly being Muslim.
A modern way of ruling
Frederick's reforms reduced the privileges and political power of bishops and clergy, another reason for his conflict with the Church. Before he was 40, he issued the Liber Augustalis, also called the Costituzioni di Melfi, a constitution with a legal and judicial code for the Kingdom of Sicily.
Instead of leaving administration to noble families, Frederick built a centralised government supported by trained functionaries and efficient bureaucrats. The university in Naples could educate those officials, but its purpose was wider: it was free, nonsectarian and open to foreigners, with student lodgings, a rent cap and scholarships for students who could not afford textbooks. Frederick also regulated medicine. Doctors had to qualify at the Schola Medica Salernitana, the prestigious medical school in Salerno, rather than practising without formal training.
Dignitas sexus: the dignity of women
The 1231 constitution included an unusually extensive protection called dignitas sexus, the dignity of women. Sexual assault could be punished by death whether the victim was a maid, married woman, nun or sex worker. A woman could report the crime and receive legal protection. Reparatory marriage was forbidden, and witnesses who saw or heard the assault but did nothing faced a heavy fine.
| Protection | What it meant |
|---|---|
| Inheritance | Women could inherit their fathers' possessions |
| Widowhood | Widows had the right to a public attorney |
| Family liability | A wife or daughter was not punished for the crimes of a husband or father |
| Sexual violence | The law recognised the crime, protected the victim and rejected forced reparatory marriage |
| Witnesses | People who failed to intervene after witnessing an assault could receive a heavy fine |
A legacy across the Mezzogiorno
Frederick was clever, energetic, ambitious and unusually accepting of differences. His natural son Manfredi described his death to his half-brother Corrado as the setting of a sun that had protected justice and peace. The image captures the sense of absence that followed him, but the institutions and landscapes he shaped continued to work long after his death.
Hundreds of thousands of students have graduated from the Università di Napoli Federico II over its 800 years. Across Basilicata, Calabria, Campania, Puglia and Sicily, an itinerary in his footsteps can connect the castles, towns, churches and infrastructure commissioned during his reign.
