removed from their old country estates and brought into residence in
the new castle towns, but this in itself did not necessarily mean subjec-
tion. Certainly they were now under constant scrutiny, utterly reliant
on their salaries, and virtually denied alternative employment. They
were infinitely more dependent than they had ever been; yet they were
far from quiescent. Paradoxically, the establishment of the Tokugawa
peace had created circumstances that not only enabled samurai to
question their daimyo's prerogative but, on occasion, compelled them
to do so and so made inevitable a degree of political ferment.
In theory, of course, no challenge to daimyo authority should have
been possible. In accepting each daimyo's submission, the Tokugawa
government guaranteed its support to every one of them in turn. Their
legal right to govern their
han
was therefore unassailable. So, too, was
a certain moral obligation, for Heaven had selected each one of them
for precisely that position. As Uesugi Harunori, daimyo of Yonezawa,
expressed it in a piece of calligraphy written on his accession in 1767,
this obligation was clear: "Father and Mother of the People," the
inscription read, followed by a poem, "Inheriting the command of this
domain, I must never forget that I am father and mother to my peo-
ple."

There were also practical considerations, as the daimyo, it was
thought, were the custodians of secret traditions enabling them to rule
far more effectively than ordinary men could. Such, at least, was
believed of the daimyo of Saga, alleged in
Hagakure
to have had a
number of secret books entrusted to him on his accession.

For all of
these reasons, it was the clear duty of the samurai to obey their
daimyo, even, for some favored samurai in the early seventeenth cen-
tury, to follow him to the grave in token of their loyalty, devotion, and
obedience.
Yet in practice there were difficulties. The daimyo of Tokugawa
Japan, no less than their Sengoku predecessors, walked a tightrope -
nearer to the ground, perhaps, and slightly slacker, but still needing to
be traversed with the utmost care. Many realized how volatile their
vassals could be, sometimes feeling impelled to warn them, as did the
daimyo of Shonai in
1648,
against "factious, conspiratorial, or obstruc-
tive behavior" or, as did the young daimyo of Aizu forty years later,
demanding of his senior vassals a special oath of loyalty, signed in
