  Here we present the current state of knowledge on the long-term evolution of
Saturn's moon system due to tides within Saturn. First we provide some
background on tidal evolution, orbital resonances and satellite tides. Then we
address in detail some of the present and past orbital resonances between
Saturn's moons (including the Enceladus-Dione and Titan-Hyperion resonances)
and what they can tell us about the evolution of the system. We also present
the current state of knowledge on the spin-axis dynamics of Saturn: we discuss
arguments for a (past or current) secular resonance of Saturn's spin precession
with planetary orbits, and explain the links of this resonance to the tidal
evolution of Titan and a possible recent cataclysm in the Saturnian system. We
also address how the moons' orbital evolution, including resonances, affects
the evolution of their interiors. Finally, we summarize the state of knowledge
about the Saturnian system's long-term evolution and discuss prospects for
future progress.
