Question: Which European empire, divided into autonomous kingdoms and ruled by an emperor with little authority outside of his own kingdom, is the subject of the "Annales mosellani"?

<P0-S0> The Annales mosellani or mosellenses ("AM") or Moselle Annals are a set of minor "Reichsannalen" (annals of the Carolingian Empire) covering the years 703 to 798. <P0-S1>  Its entries are brief and unliterary, but broad in scope and generally accurate. <P0-S2>  They have only partially been translated into English. <SEP> <P1-S0> The Byzantine–Bulgarian wars were a series of conflicts fought between the Byzantines and Bulgarians which began when the Bulgars first settled in the Balkan peninsula in the 5th century, and intensified with the expansion of the Bulgarian Empire to the southwest after 680 AD. <P1-S1>  The Byzantines and Bulgarians continued to clash over the next century with variable success, until the Bulgarians, led by Krum, inflicted a series of crushing defeats on the Byzantines. <P1-S2>  After Krum died in 814, his son Omurtag negotiated a thirty-year peace treaty. <P1-S3>  In 893, during the next major war, Simeon I, the Bulgarian emperor, defeated the Byzantines while attempting to form a large Eastern European Empire, but his efforts failed. <SEP> <P2-S0> Austria-Hungary, often referred to as the Austro-Hungarian Empire or the Dual Monarchy in English-language sources, was a constitutional union of the Austrian Empire (the Kingdoms and Lands Represented in the Imperial Council, or "Cisleithania") and the Kingdom of Hungary (Lands of the Crown of Saint Stephen or "Transleithania") that existed from 1867 to 1918, when it collapsed as a result of defeat in World War I. <P2-S1>  The union was a result of the Austro-Hungarian Compromise of 1867 and came into existence on 30 March 1867. <P2-S2>  Austria-Hungary consisted of two monarchies (Austria and Hungary), and one autonomous region: the Kingdom of Croatia-Slavonia under the Hungarian crown, which negotiated the Croatian–Hungarian Settlement ("Nagodba") in 1868. <P2-S3>  It was ruled by the House of Habsburg, and constituted the last phase in the constitutional evolution of the Habsburg Monarchy. <P2-S4>  Following the 1867 reforms, the Austrian and the Hungarian states were co-equal. <P2-S5>  Foreign affairs and the military came under joint oversight, but all other governmental faculties were divided between respective states. <SEP> <P3-S0> The Carolingian Empire (800–888) was a large empire in western and central Europe during the early Middle Ages. <P3-S1>  It was ruled by the Carolingian dynasty, which had ruled as kings of the Franks since 751 and as kings of the Lombards of Italy from 774. <P3-S2>  In 800, the Frankish king Charlemagne was crowned emperor in Rome by Pope Leo III in an effort to revive the Roman Empire in the west during a vacancy in the throne of the eastern Roman Empire. <P3-S3>  After a civil war (840–43) following the death of Emperor Louis the Pious, the empire was divided into autonomous kingdoms, with one king still recognised as emperor, but with little authority outside his own kingdom. <P3-S4>  The unity of the empire and the hereditary right of the Carolingians continued to be acknowledged.
