and royal domains and 1/15 in the country.

From 1150 to 1400, resistance was an ordinary remedy for
political disagreements. If a popular leader raised his standard
in a popular cause, an irregular army could be assembled in a
day. (There was no regular army, since England was protected by
the sea from invasion.) So misgovernment by a King would be
quickly restrained. Society recovered quickly from conflict and
civil war because the national wealth consisted chiefly in flocks
and herds and in the simple buildings inhabited by the people. In
a week after armed resistance, the peasant was driving his team.
There was little furniture, stock of shops, manufactured goods,
or machinery that could be destroyed.

The feudal army was summoned for the last time in the 100 year
war with France, which began in 1337. In it the English longbow
was used to pierce French knights' armor. Gunpowder and guns and
cannon were introduced in 1338. They became common by 1372 and
foresaw the end to the competition between the strength of arrows
to pierce and the heaviness of armor to resist. Featherbeds and
blooded horses were favorite spoils of war brought back to
England.

Many lords got men to fight with them by livery and maintenance
employment
agreements such as this one of 1374:
"Bordeaux, February 15. This indenture, made between our lord
King John [of Gaunt, of Castile, etc.] of the one part and Symkyn
Molyneux, esquire, of the other part, witnesses that the said
Symkyn is retained and will remain with our said lord for peace
