Assessing a state’s strength
When looking at the nature of these various states one
important question to ask is: if attacked, does a ruler have
sufficient power to defend himself with his own resources, or
will he always have to rely on the protection of others? To
make the question more precise, let’s say that a ruler who
has enough men or enough money to put together an army
that can take on all comers is, by my definition, capable
of defending himself, while a ruler who can’t take on an
enemy in the field but has to withdraw behind his city
walls and defend those, is one who will always be in need of
outside help. We’ve already said something about the first
kind of ruler [Chapter 6] and later on there’ll be more
[Chapters 11–13]. As for the second kind, one can only
encourage them to fortify their home towns and keep them
well supplied, while leaving the surrounding countryside
entirely to its fate. If a ruler has built good fortifications and
managed his relationship with his subjects as suggested above
and further elaborated in the following pages, his enemies
will always think twice before attacking him. People are
always wary of projects that present obvious difficulties, and
attacking a well-defended town and a ruler whose subjects
don’t hate him is never an easy proposition.
German cities are completely independent, don’t have much
territory around them and obey the emperor only when it
suits. They are not afraid of him, nor of any other powerful
