Watched the Assassins' Creed trailer, huh? This is such a broad question that it's really impossible to answer satisfactorily in one post. For in-depth reading, I'd recommend Blackburn and Dumville's Kings, Currency and Alliances, Molyneaux's The Making of the Kingdom of the English in the Tenth Century, Lavelle's Alfred's Wars and The Danes in Wessex, Naismith's Money and Power in Anglo-Saxon England, Baker and Brookes' Beyond the Burghal Hidage, Baker, Brookes and Reynolds' Landscapes of Defence, Rumble and Hill's seminal The Defence of Wessex, Farr and Brown's Mercia: An Anglo-Saxon Kingdom in Europe, Dorothy Whitelock's translation and edit of The Anglo-Saxon Chronicle, Keynes and Lapidge's translation of Asser's Vita Ælfredi, Stafford's Unification and Conquest and Gender, Family and the Legitimation of Power and Yorke's Kings and Kingdoms in Anglo-Saxon England, Nunneries and the Anglo-Saxon Royal Houses and The Anglo-Saxons, as well as Stenton's perennial Anglo-Saxon England and Higham's The Anglo-Saxon World.

I wrote a post here that looked at Anglo-Saxon coinage in a bit more detail. By the Ninth Century, the Anglo-Saxon economy was relatively extensively monetised. Increasingly close political co-operation between Wessex and Mercia from the 840s onwards lead to an increasingly unified coinage across both polities that was essentially contiguous in size, weight, Troy Grain weight, and, increasingly, design. Although local economies still relied to an extent on barter, coinage was very much used for everyday transactions, as can be evidenced in the designs of the coins and the patterns of their find sites. In the late Ninth Century, the principal sites of coin production were London, Canterbury and Rochester; the great expansion of minting and increasingly tight regulations on design consistency wouldn't appear until the early 900s. Coinage, especially London-minted, also had important symbolic value. Alfred notably uses an 870s London issue to celebrate his alliance with Ceolwulf II of Mercia. In the 880s/90s, the Danes in East Anglia also mint their own imitations of Alfred's London coinage, presumably in hopes of trading with the English more easily.

One of the mainstays of the Anglo-Saxon economy was wool, and so sheep were an important and commonplace crop. Wool farming could be extremely lucrative. Cattle were also fairly common, especially in areas that were more marginal for arable farming. The excavations of the tenth-century productive site at the Stafford burh show large volumes of cattle were butchered to provide meat rations for Mercian garrisons, along with a wide variety of game. Game was an important source of meat for the Anglo-Saxons, particularly birds. Ælfric's Colloquy suggests that bird-catchers and fishermen were both important figures in the provision of food to a community.

Oxen were also important animals due to their use in arable agriculture. Like sheep, while they were owned individually, they appear to have been kept communally. Owning an ox, or a share thereof, gave a farmer a stake in the communal plough teams. Horses were also important although they weren't typically used for ploughing. The Anglo-Saxons reportedly rode horses to battle, but didn't really make use of cavalry, seemingly preferring to fight on foot. On the other hand, horse racing was by all accounts a popular pastime and horse breeding was economically important. Toponymic evidence suggest that stud farms were fairly commonplace.

Transportation is a muddy subject to cover. We know that England's Roman roads were still in use during the period, and indeed landholders were frequently obliged to levy manpower for their upkeep and maintenance, as well as for the maintenance of bridges. A variety of smaller roads and herepaths were also in use. Rivers formed a major transport artery, especially for trade and the transport of goods. Coastal trade was also important, and material culture evidence and works like Ælfric's Colloquy suggest that Wessex in particular had close economic and some cultural links to France. Indeed, Ælfred's defensive burh network was specifically designed to block rivers and control major bridges, fords and junctions to deny their use to the Danes and to allow English armies to rapidly outmanouevre them, to great effect.

"Civil Life" is a fairly broad umbrella so it's tricky to address. The majority of the population was agrarian and lived in rural villages. London, Rochester, Canterbury, Hamwic, Exeter, Gloucester and Tamworth were important urban centres, with a gradual proliferation of urban sites appearing in the ninth century, particularly on the West coast with the development of Bristol and Chester. The majority of the population was engaged in farming, and heavily seasonal. The majority of the population were likely tenant farmers who paid their rents in labour on their lord's land, although up to 10% of the population (if not more in this period) were slaves, typically Welsh. Society was fairly stratified, but this wasn't necessarily a barrier to success, and archaeological evidence suggests that Freemen in particular could be relatively prosperous and comfortable. Women were typically employed in spinning and weaving, which would be carried out on spindle whorls in the home.

English fashions ebbed and flowed over the centuries, but broadly speaking male fashion was for a tunic of variable length, typically accompanied by a cloak and leg-wraps in colder weather, and female fashion was typically for a loose gown worn over a kirtle, over which wealthier women would likely have worn a mantle, and a wimple kept in place by a head rail. By the ninth century, fashion had broadly moved away from belts in favour of flaxen straps, and buckles were largely superseded by decorated strap ends. These form a major component of extant metalwork finds, and seem to have been a popular way of showing wealth and status, coming in an array of increasingly intricate styles. Jewelry was popular across society, particularly brooches, which were typically ornate metalwork with inlaid glass or jewels, as well as hilts, scabards and seaxes. While the wealthy may have worn gold inlaid with rubies or garnets, archaeological evidence suggests that the poorer members of society also wore similar styles, but with bronze or brass, or silver, and with cut glass instead of precious stones.

There was a fairly sophisticated legal code, which included a wide array of weregild for crimes from burglary and affray to sexual assault and murder. The law contained certain protections for orphans, widows, women and even slaves. Although Christianity was not universal, it was overwhelmingly the principal religion, as England had been largely Christianised from the 7th century onwards. Although literary and graffiti evidence suggests that an array of 'Pagan' practices or beliefs survived, these were either largely tolerated by the Church or actively subsumed into Church practice (if not dogma) as they didn't directly challenge established doctrine. Charms and curses, for example, were broadly believed in, and contemporary medical texts suggest a belief in Elves or "Fae Folk".

Literacy is likely to have been higher than commonly assumed. Asser records that Ælfred actively mandated that his ealdormen or their sons had to be sufficiently literate and numerate to carry out the bureaucracy of their counties themselves if need be, and also actively supported the production of books in English, including the Bible, as well as penning his own theological works. Land ownership and rights were typically conferred and managed by charters, and wills were common for managing succession, even among the Freeman peasantry.
