the prince
and didn’t want to submit to the harsh conditions imposed
by the new king.
Of course, when a king returns to win back a territory that
has rebelled like this, he is less likely to lose it a second time.
Having learned from the rebellion, he’ll have fewer scruples
when it comes to punishing troublemakers, interrogating sus-
pects and strengthening any weak points in his defences. So
while the first time Louis invaded Milan it took no more than
a little sword-rattling along the borders from Ludovico to
force a retreat, the second time it would take the whole world
to defeat his armies and drive them out of Italy. This for the
reasons listed above. All the same, they were driven out both
times.
The general reasons behind the first French defeat have
been discussed. It remains to explain why Louis lost Milan
the second time and to see what counter-measures he could
have taken and what options a ruler has in a situation like
this if he wants to hold on to his conquest.
Needless to say, any territory annexed to the realm of a
conquering ruler may or may not be in the same geographical
region and share the same language. If it is and the language
is shared, the territory will be much easier to hold on to,
especially if its people are not used to the freedom of self-
government. In that case all you have to do is eliminate the
family of the previous ruler and your hold on power is guaran-
teed. Everything else in the territory can then be left as it was
and, given that there are no profound differences in customs,
people will accept the situation quietly enough. Certainly
this has proved true in Burgundy, Brittany, Gascony and
Normandy, all of which have now been under French rule for
many years. Even where there is some difference in language,
the customs of these territories are similar and people can get
along with each other. So a ruler who has taken territories in
these circumstances must have two priorities: first, to elimin-
ate the family of the previous rulers; second, to leave all laws
