from the treasure hunters depict the two kings, "indicating an alliance between the two kingdoms—at least, for a time—that was previously unknown to historians", according to the report. A report by The Guardian adds that"The presence of both kings on the two emperor coins suggests some sort of pact between the pair. But the rarity of the coins also suggests that Alfred quickly dropped his ally, who was just about written out of history". Alfred also reformed the administration of justice, issued a new law code and championed a revival of scholarship and education. He gathered scholars from around England and elsewhere in Europe to his court, and with their help translated a range of Latin texts into English, doing much of the work personally, and orchestrated the composition of the Anglo-Saxon Chronicle. As a result of these literary efforts and the political dominance of Wessex, the West Saxon dialect of this period became the standard written form of Old English for the rest of the Anglo-Saxon period and beyond. The Danish conquests had destroyed the kingdoms of Northumbria and East Anglia and divided Mercia in half, with the Danes settling in the north-east while the south-west was left to the English king Ceolwulf, allegedly a Danish puppet. When Ceolwulf's rule came to an end he was succeeded as ruler of "English Mercia" not by another king but by a mere ealdorman, Aethelred, who acknowledged Alfred's overlordship and married his daughter Ethelfleda. The process by which this transformation of the status of Mercia took place is unknown, but it left Alfred as the only remaining English king. Unification of England and the Earldom of Wessex After the invasions of the 890s, Wessex and English Mercia continued to be attacked by the Danish settlers in England, and by small Danish raiding forces from overseas, but these incursions were usually defeated, while there were no further major invasions from the continent. The balance of power tipped steadily in favour of the English. In 911 Ealdorman Æthelred died, leaving his widow, Alfred's daughter Æthelflæd, in charge of Mercia. Alfred's son and successor Edward the Elder, then annexed London, Oxford and the surrounding area, probably including Middlesex, Hertfordshire, Buckinghamshire and Oxfordshire, from Mercia to Wessex. Between 913 and 918 a series of English offensives overwhelmed the Danes of Mercia and East Anglia, bringing all of England south of the Humber under Edward's power. In
