the crown, in 1327, amounted to more than eighty towns and castles. [60]
The "good constable" Davalos, in the time of Henry the Third, could ride
through his own estates all the way from Seville to Compostella, almost
the two extremities of the kingdom. [61] Alvaro de Luna, the powerful
favorite of John the Second, could muster twenty thousand vassals. [62] A
contemporary, who gives a catalogue of the annual rents of the principal
Castilian nobility at the close of the fifteenth or beginning of the
following century, computes several at fifty and sixty thousand ducats a
year, [63] an immense income, if we take into consideration the value of
money in that age. The same writer estimates their united revenues as
equal to one-third of those in the whole kingdom. [64]

These ambitious nobles did not consume their fortunes, or their energies
in a life of effeminate luxury. From their earliest boyhood they were
accustomed to serve in the ranks against the infidel, [65] and their whole
subsequent lives were occupied either with war, or with those martial
exercises which reflect the image of it. Looking back with pride to their
ancient Gothic descent, and to those times, when they had stood forward as
the peers, the electors of their sovereign, they could ill brook the
slightest indignity at his hand. [66] With these haughty feelings and
martial habits, and this enormous assumption of power, it may readily be
conceived that they would not suffer the anarchical provisions of the
constitution, which seemed to concede an almost unlimited license of
rebellion, to remain a dead letter. Accordingly, we find them perpetually
convulsing the kingdom with their schemes of selfish aggrandizement. The
petitions of the commons are filled with remonstrances on their various
oppressions, and the evils resulting from their long, desolating feuds. So
that, notwithstanding the liberal forms of its constitution, there was
probably no country in Europe, during the Middle Ages, so sorely afflicted
with the vices of intestine anarchy, as Castile. These were still further
