In November 1620, the Pilgrim Fathers made landfall off Plymouth Rock in Massachusetts. It wasn’t the best time of year to arrive. The New England winter was more ferocious than anything the predominantly East Anglian settlers were used to. Nor were the precedents exactly encouraging. The first British settlement in North America had disappeared without trace. The second (in Jamestown, Virginia) had survived, but only after terrible loss of life.

The word Welsh derives from an Anglo-Saxon root, Wealas, which means slave or foreigner. There, in a nutshell, is all you need to know about the politics of sixth-century Britain. The incoming Angles, Jutes and Saxons had turned the native British Celts into foreigners in their own land; not quite slaves perhaps, but humiliatingly subject all the same.

It began with the Black Death.

In Bristol, where it struck first in 1348, some 45 per cent of the population died. Across the country, the death toll was lower, but still vast. As the country fell dying, the only growth industry was that of burial, and since priests were constantly in contact with the sick and dying, the death rate among the clergy probably exceeded even that of the general population. In January 1349, the Bishop of Bath and Wells wrote, ‘Priests cannot be found for love nor money … to visit the sick and administer the last sacraments.’ Since those last sacraments would have been viewed as of vital importance in Catholic England, the problem was a serious one. Dreadful times bring drastic remedies. The bishop went on to say that, in the absence of a priest, it would be proper for the dying to confess their sins to a lay person or even (steady on!) ‘to a woman if no man is available’.
