In 874 the march of the Danes from Lindsey to Repton drove Burgred from his kingdom.
Farther south, heavy crops of wheat, turnips and other cereals and green crops are not uncommon, while barley is cultivated about Repton and Gresley, and also in the east of the county, in order to supply the Burton breweries.
In the 9th century the district suffered frequently from the ravages of the Danes, who in 874 wintered at Repton and destroyed its famous monastery, the burial-place of the kings of Mercia.
The early divisions of the county were known as wapentakes, five being mentioned in Domesday, while 13th-century documents mention seven wapentakes, corresponding with the six present hundreds, except that Repton and Gresley were then reckoned as separate divisions.
The chancel of the church at Repton is assigned to the second half of the 10th century, though subsequently altered, and the crypt beneath is supposed to be earlier still; its roof is supported by four round pillars, and it is approached by two stairways.
