Most items were part of a burial of a nobleman culture in the northern part of the Benin Empire. Evidence of long-distance trade between Benin and Portugal was also discovered through the thousands of glass beads found at Old Cairo at the workshops of Fustat. The development of the Benin Kingdom can be attributed to the proficiency at advanced metallurgy seen in the bronze jewellery crafted by local artisans.

set up impermanent camps, which were called longphorts by the Irish—this period of Viking raids on the coasts of Ireland has been named the longphort phase after these types of settlements. Ireland in the 9th century was organised into an amalgam of small kingdoms, called tuatha. These kingdoms were sometimes grouped together and ruled by a single, provincial ruler. If such a ruler could establish and maintain authority over a portion of these tuatha, he was sometimes granted the title of High King.

also experienced significant Viking incursions during the 9th century. The Vikings established themselves in coastal regions, usually in northern Scotland, and in the northern islands such as Orkney and Shetland. The Viking invasion and settlement in Scotland provided a contributing factor in the collapse of the kingdoms of the Picts, who inhabited most of Scotland at the time. Not only were the Pictish realms either destroyed or severely weakened, the Viking invasion and settlements may have been the reason for the movement of Kenneth MacAlpin, the king of Dál Riata at that time. The kingdom of Dál Riata was located on the western coast of Scotland, and Viking incursions destroyed it after the death of its previous king, Áed mac Boanta in 839, according to the Annals of Ulster. This may have caused the new king, MacAlpin, to move to the east, and conquer the remnants of the Pictish realms. MacAlpin became king of the Picts in 843 and later kings would be titled as the King of Alba or King of Scots.


Art

Art in the 9th century was primarily dedicated to the Gospel and employed as basic tools of liturgy of the Roman Orthodox Church. Thousands of golden art objects were made: Sacred cups, vessels, reliquaries, crucifixes, rosaries, altarpieces, and statues of the Virgin and Child or Saints all kept the flame of western art from dying out. Architecture began to revive to some extent in the West by the 9th century, taking the form of Church facilities of all kinds, and the first castle fortifications since Roman times began to take form in simple "moat and bailey" castles, or simple "strong point" tower structures, with little refinement.
