Please answer the following question: Information: - Manuel I Komnenos (or Comnenus "Manoul I Komnnos"; 28 November 1118 24 September 1180) was a Byzantine Emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire had seen a resurgence of its military and economic power, and had enjoyed a cultural revival. - The King of Hungary was the head of state of the Kingdom of Hungary from 1000 (or 1001) to 1918. The style of title ""Apostolic King"" was confirmed by Pope Clement XIII in 1758 and used afterwards by all the Kings of Hungary, so after this date the kings are referred to as "Apostolic King of Hungary". - Stephen IV ( , , ; 113311 April 1165 ) was King of Hungary and Croatia , ascending to the throne in 1163 when he usurped the crown of his nephew , Stephen III. He was the third son of Bela II of Hungary , and when his conspiracy against his brother failed , Geza II , he was exiled from Hungary in the summer of 1157 . He first sought refuge in the Holy Roman Empire , but received no support from Emperor Frederick I. Shortly afterwards he moved to the Byzantine Empire , where he married a niece of Emperor Manuel I Komnenos , Maria Komnene , and converted to the Orthodox Church . - The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, which had been founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the "Roman Empire" (tr. ), or "Romania", and to themselves as "Romans". - The Holy Roman Empire was a multi-ethnic complex of territories in central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806. The largest territory of the empire after 962 was the Kingdom of Germany, though it also came to include the Kingdom of Bohemia, the Kingdom of Burgundy, the Kingdom of Italy, and numerous other territories. - The Komnenian Restoration is the term used by historians to describe the military, financial, and territorial recovery of the Byzantine Empire under the Komnenian dynasty, from the accession of Alexios I Komnenos in 1081 to the death of Andronikos I Komnenos in 1185. At the onset of the reign of Alexios I, the empire was reeling from its defeat by the Seljuk Turks at the Battle of Manzikert in 1071. The empire was also being threatened by the Normans of Robert Guiscard, who were invading the Balkans from their base in southern Italy. All this occurred as the empire's military institution was in disarray and had grown increasingly reliant on mercenaries. Previous emperors had also squandered the large gold deposits of Constantinople, so the defense of the empire had broken down, and there were few troops to fill the gaps. - An empire is defined as "an aggregate of nations or people ruled over by an emperor or other powerful sovereign or government, usually a territory of greater extent than a kingdom, as the former British Empire, French Empire, Brazilian Empire, Russian Empire, Ottoman Empire, Byzantine Empire or Roman Empire." An empire can be made solely of contiguous territories such as the Austro-Hungarian Empire, or of territories far remote from the homeland, such as a colonial empire. - The Kingdom of Hungary was a monarchy in Central Europe that existed from the Middle Ages into the twentieth century (10001946 with the exception of 19181920). The Principality of Hungary emerged as a Christian kingdom upon the coronation of the first king Stephen I at Esztergom in about the year 1000; his family (the Arpad dynasty) led the monarchy for 300years. By the 12th century, the kingdom became a European middle power within the Western world. - The Kingdom of Germany or German Kingdom ("Teutonic Kingdom") developed out of the eastern half of the former Carolingian Empire. Like Anglo-Saxon England and medieval France, it began as "a conglomerate, an assemblage of a number of once separate and independent... "gentes" [peoples] and "regna" [kingdoms]." East Francia ("Ostfrankenreich") was formed by the Treaty of Verdun in 843, and was ruled by the Carolingian dynasty until 911, after which the kingship was elective. The initial electors were the rulers of the stem duchies, who generally chose one of their own. After 962, when Otto I was crowned emperor, the kingdom formed the bulk of the Holy Roman Empire, which also included Italy (after 951), Bohemia (after 1004) and Burgundy (after 1032). What is the relationship between 'stephen iv of hungary' and 'arpad dynasty'?
