Question: Read this and answer the question

No Islamic visual images or depictions of God are meant to exist because it is believed that such artistic depictions may lead to idolatry. Moreover, Muslims believe that God is incorporeal, making any two- or three- dimensional depictions impossible. Instead, Muslims describe God by the names and attributes that, according to Islam, he revealed to his creation. All but one sura of the Quran begins with the phrase "In the name of God, the Beneficent, the Merciful". Images of Mohammed are likewise prohibited. Such aniconism and iconoclasm can also be found in Jewish and some Christian theology.

Why is depicting God forbidden in the Islamic world?
Answer: such artistic depictions may lead to idolatry

Input: Article: Viking invasions began in the 9th century, followed by more permanent settlements, particularly along the east coast of Ireland, the west coast of modern-day Scotland and the Isle of Man. Though the Vikings were eventually neutralised in Ireland, their influence remained in the cities of Dublin, Cork, Limerick, Waterford and Wexford. England however was slowly conquered around the turn of the first millennium AD, and eventually became a feudal possession of Denmark. The relations between the descendants of Vikings in England and counterparts in Normandy, in northern France, lay at the heart of a series of events that led to the Norman conquest of England in 1066. The remnants of the Duchy of Normandy, which conquered England, remain associated to the English Crown as the Channel Islands to this day. A century later the marriage of the future Henry II of England to Eleanor of Aquitaine created the Angevin Empire, partially under the French Crown. At the invitation of a provincial king and under the authority of Pope Adrian IV (the only Englishman to be elected pope), the Angevins invaded Ireland in 1169. Though initially intended to be kept as an independent kingdom, the failure of the Irish High King to ensure the terms of the Treaty of Windsor led Henry II, as King of England, to rule as effective monarch under the title of Lord of Ireland. This title was granted to his younger son but when Henry's heir unexpectedly died the title of King of England and Lord of Ireland became entwined in one person.

Now answer this question: When did Viking invasions begin in the British Isles?

Output:
9th century
