Pepin, King of the Franks, -768

Pepin the Short German: Pippin der Jüngere, French: Pépin le Bref, c. 714 – 24 September 768 was the King of the Franks from 751 until his death in 768. He was the first of the Carolingians to become king.

The younger son of the Frankish prince Charles Martel and his wife Rotrude, Pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of St. Denis. Succeeding his father as the Mayor of the Palace in 741, Pepin reigned over Francia jointly with his elder brother Carloman. Pepin ruled in Neustria, Burgundy and Provence, while his older brother Carloman established himself in Austrasia, Alemannia and Thuringia. The brothers were active in suppressing revolts led by the Bavarians, Aquitanians, Saxons and the Alemanni in the early years of their reign. In 743, they ended the Frankish interregnum by choosing Childeric III, who was to be the last Merovingian monarch, as figurehead king of the Franks.

Being well disposed towards the church and papacy on account of their ecclesiastical upbringing, Pepin and Carloman continued their father's work in supporting Saint Boniface in reforming the Frankish church, and evangelising the Saxons. After Carloman, who was an intensely pious man, retired to religious life in 747, Pepin became the sole ruler of the Franks. He suppressed a revolt led by his half-brother Grifo, and succeeded in becoming the undisputed master of all Francia. Giving up pretense, Pepin then forced Childeric into a monastery and had himself proclaimed king of the Franks with support of Pope Zachary in 751. The decision was not supported by all members of the Carolingian family and Pepin had to put down a revolt led by Carloman's son, Drogo, and again by Grifo.

As king, Pepin embarked on an ambitious program to expand his power. He reformed the legislation of the Franks and continued the ecclesiastical reforms of Boniface. Pepin also intervened in favour of the papacy of Stephen II against the Lombards in Italy. He was able to secure several cities, which he then gave to the Pope as part of the Donation of Pepin. This formed the legal basis for the Papal States in the Middle Ages. The Byzantines, keen to make good relations with the growing power of the Frankish empire, gave Pepin the title of Patricius. In wars of expansion, Pepin conquered Septimania from the Islamic Umayyads, and subjugated the southern realms by repeatedly defeating Waiofar and his Gascon troops, after which the Gascon and Aquitanian lords saw no option but to pledge loyalty to the Franks. Pepin was, however, troubled by the relentless revolts of the Saxons and the Bavarians. He campaigned tirelessly in Germany, but the final subjugation of these tribes was left to his successors.

Pepin died in 768 and was succeeded by his sons Charlemagne and Carloman. Although unquestionably one of the most powerful and successful rulers of his time, Pepin's reign is largely overshadowed by that of his more famous son, Charlemagne.

Pepin died during a campaign, in 768 at the age of 54. He was interred in the Basilica of Saint Denis in modern-day Metropolitan Paris. His wife Bertrada was also interred there in 783. Charlemagne rebuilt the Basilica in honor of his parents and placed markers at the entrance.

The Frankish realm was divided according to the Salic law between his two sons: Charlemagne and Carloman I.

Historical opinion often seems to regard him as the lesser son and lesser father of two greater men, though a great man in his own right. He continued to build up the heavy cavalry which his father had begun. He maintained the standing army that his father had found necessary to protect the realm and form the core of its full army in wartime. He not only contained the Iberian Muslims as his father had, but drove them out of what is now France and, as important, he managed to subdue the Aquitanians and the Gascons after three generations of on-off clashes, so opening the gate to central and southern Gaul and Muslim Iberia. He continued his father's expansion of the Frankish church (missionary work in Germany and Scandinavia) and the institutional infrastructure (feudalism) that would prove the backbone of medieval Europe.

His rule, while not as great as either his father's or son's, was historically important and of great benefit to the Franks as a people. Pepin's assumption of the crown, and the title of Patrician of Rome, were harbingers of his son's imperial coronation which is usually seen as the founding of the Kingdom of France. He made the Carolingians de jure what his father had made them de facto—the ruling dynasty of the Franks and the foremost power of Europe. Known as a great conqueror, he was undefeated during his lifetime.

Pepin married Leutberga from the Danube region. They had five children. She was repudiated some time after the birth of Charlemagne and her children were sent to convents.

In 741, Pepin married Bertrada, daughter of Caribert of Laon. They are known to have had eight children, at least three of whom survived to adulthood:

Charles (Charlemagne) (2 April 742 – 28 January 814)
Carloman (751 – 4 December 771)
Pepin (756–762)
Gisela (757–810)
Berthe, died young
Adelais (Adelaide), died young, buried in Metz
Chrothais (Rothaide), died young, buried in Metz
