It occurs to me that I have had this blog up and running for several months now—I’ve only made a few posts, but let’s disregard that fact—and many people who happen to come across it may not know what it’s really about. Well, as previous posts can tell you, it’s to give my professional writing a kickstart by allowing me to put down my thoughts informally, but well enough organized for people to follow. And also to share some of the high points of being a medievalist. But enough of that. Here’s some material I have put together to give a somewhat scholarly overview of my project. The project itself is much larger, but what we have today is a start that should allow you to catch on if you’re unfamiliar with Carolingian Catalonia:
By way of introduction
The Spanish March of the Carolingian Empire provides an interesting and useful case study in how rulers integrated a conquered territory into the political, social, and cultural framework of the regnum francorum. From the first forays across the Pyrenees in 778 to the severing of links between local counts and their kings late in the tenth century, Frankish rulers managed personnel, patronized monasteries, and cultivated ties to people based in the March in order to maintain a sort of royal presence in the area. In this way, the Spanish March became not just a militarized frontier zone, but a prized province, a sought-after honor for members of the imperial aristocracy. When it was entrusted to loyal men of regional origins late in the ninth century, a dynasty was able to emerge gradually. The new ruling family of the March, it should be stressed, seems never to have sought autonomy, and indeed maintained loyalty to the Carolingian rulers. It was the Carolingians themselves who faced dynastic challenges in the late ninth and tenth centuries, and these issues helped to separate the monarchy from the March. What the history of the Spanish March tells us about the Carolingian Empire, then, is that relationships between local aristocrats and kings were coveted by both, and when these relationships became ultimately untenable, powerbrokers in places like the March were left to their own devices.

The beginnings of heavy Carolingian involvement in the area that became the Spanish March can be traced to a meeting of Muslim messengers and the Frankish king at Paderborn. The wali of Zaragoza submitted to Charlemagne himself and the cities over which the “king of the Saracens” had placed him. An uncertain political environment within the Abbasid caliphate perhaps provided an opportunity for ambitious local governors. Suleiman ibn al-Arabi, governor of Barcelona and Girona, was fighting against the caliph’s forces and made the appeal to the Frankish king, who had proven himself against the Saxons and Lombards. Suleiman and his son Yusuf offered Charlemagne a sort of protectorate over cities and promise of collaboration. There is no indication that these walis from northern Spain wished to enter into alliance with Charlemagne in order to truly submit to his rule, so it must be that they wanted to entice the Frankish king with lofty promises, deliver on those promises as little as possible, and therefore maximize gain for themselves.
Charlemagne was concerned with affairs on multiple fronts in 777, when the envoys came to Paderborn. He accepted the rebels’ invitation to invade Spain and in 778 crossed the Pyrenees. The king himself made way for Zaragoza via Pamplona, while a second army was to meet him after first coming through the eastern passes. We should note that troops were called in from all over the kingdom and its various parts. Eastern territories of the Frankish realm provided troops to participate in the eastern entrance of Pyrenees, with soldiers coming from the western territories at the western end of the mountains. This enabled Charlemagne to arrange his forces for a pincer movement like the one he used during the Lombard campaign and others. Most annals agree on the events of the campaign, which by all accounts ended badly with the famous Basque ambush in the Pyrenean pass at Roncevalles. Despite his ultimate failure, Charlemagne appears to have realized his goal of conquering Pamplona—without a fight—taking hostages from the governor of the city. At Zaragoza, however, he was less successful. Surviving sources from southern Gaul report that the Franks killed thousands of Muslims in battle, before having to withdraw in order to deal with a Saxon force that had crossed the Rhine. Charlemagne never returned to the southern theater again. He left to his subordinates and his son, Louis, the tasks of controlling and expanding Carolingian holdings in the area.
Louis the Pious

Louis was born during the campaign of 778; three years later he was named king of Aquitaine. By reorganizing the region as a sub-kingdom under his son (as he also did in Italy under Louis’s brother Pippin), Charlemagne did not merely give a nod toward the fact that Aquitaine had until recently been ruled by its own duke, but indeed made for more efficient management of his growing kingdom as well as further involvement in Spain. Indeed, the kings’ men launched numerous campaigns, nominally under the young Louis. The Astronomer and various annalists’ accounts of Louis’s reign in Aquitaine reveal just how great the effort was. Just as Charlemagne’s interest in Spain was sparked by envoys from Muslim leaders in 777, Louis faced similar opportunities. The young king of Aquitaine even received Muslim envoys and agreed to peace in 790. Of course, not all Frankish interaction with their Muslim neighbors was quite so peaceful. Evidence points to many armed confrontations during the late eighth and early ninth centuries. In 785, Girona submitted to the Franks, according to the Moissac Chronicle, which states that “the men of Girona delivered the city . . . to king Charles” even though Charlemagne was in Saxony that year, and as noted never personally ventured south of the Pyenees after 778. Nevertheless, the successful annexation of Girona resulted in the creation of the first county in the Spanish frontier area, with the Frank Rostagnus as its count.The Pyrenean region was incorporated into the new kingdom of Aquitaine and placed in the hands of the very young Louis and his advisors.In 793, the year Louis turned fifteen, William, duke of Toulouse, led Frankish forces against the Saracens, who ventured forth from Hispania into parts of Gothia and terrorized the Christians there. The Muslim raid may have been prompted by Charlemagne’s attention to other matters, namely in Saxony and his canal project designed to link the Rhine and Danube. Other combat followed, often instigated by the Franks after Louis reached his majority. Indeed, the Astronomer reports a rather significant campaign in the late 790s that burned the city of Lleida and ravaged the countryside around Huesca, but no permanent conquest resulted. Louis later set his sights on cities farther south. Because of this campaign, he was able to inflict damage on the Muslim troops raised to stop him and return to Aquitaine with booty plundered from along the route, including the cities of Tarragona and Tortosa. These and other minor campaigns did not result in further conquests as much as shows of Frankish strength, so they can be said to have set the geographical limits of Frankish rule south of the Pyrenees.
The most important campaigning revolved around the city of Barcelona, which was to become the principal seat of power in the March. By 797 the Franks had formally acquired the city by negotiation, but its Muslim governor seems never to have actually surrendered it. Louis needed a rather extended campaign to affirm Carolingian control of the city. After meeting at Toulouse to develop strategy, the king of Aquitaine set off for Barcelona in 800. He divided his army in three parts. Despite hopeful expectations that Barcelona would surrender like Girona, it seems that Louis set off with ample preparations for a long siege. One Frankish detachment successfully blocked Muslim relief forces; these Muslims withdrew, freeing the Franks to join their comrades at Barcelona, where resistance was tough. The siege of Barcelona lasted into winter, proving a longer operation than the Franks were accustomed to, but causing the city to suffer and become demoralized. Louis appeared with his reserve troops in early 801, and six weeks later Barcelona capitulated, allowing the king a triumphal entrance on Easter Sunday 801.When all is taken into account, the Carolingian kings needed intermittent fighting from 778 to 801 to solidify their control of the Christians in the future Catalonia—approximately the same length of time as they needed to accomplish the same task for pagan Saxony. The conquest of Saxony occupies pages upon pages in the accounts of those who knew and worked for Charlemagne as well as in those of modern historians. It is about time that the Spanish March, of Carolingian Catalonia, became as well known.
As always, please let me know if any of this is unintelligible, incorrect, or otherwise needs to be fixed.

 As the annals make clear, the king was preoccupied first and foremost with the Saxons, as they hold the first place in the year’s entry; the fact that he was at Paderborn for the assembly is also telling. See the entries for the years 776 and 777 in ARF, 42-51. See Abadal, El domini carolingi a Catalunya, 39-41, which points out that Arabic chroniclers downplay the significance of the meeting.

 The argument that the move placated Aquitanian particularism stems from the harsh fighting earlier in the eighth century. See Leonce Auzias, L’Aquitaine carolingienne (Toulouse, 1937), 1-63. Archibald Lewis, The Development of Southern French and Catalan Society, 718-1050 (Austin, 1965), 51, discusses the region’s particularism as a possible motivation behind the creation of the kingdom. But see Collins, Charlemagne, 70 and 73.
