  The infrared is a key wavelength regime for probing the dusty, obscured
nuclear regions of active galaxies. We present results from an infrared study
of 87 nearby Seyfert galaxies using the Spitzer Space Telescope and
ground-based telescopes. Combining detailed modelling of the 3 - 100 micron
spectral energy distributions with mid-IR spectral diagnostics and
near-infrared observations, we find broad support for the unified model of
AGNs. The IR emission of Seyfert 1s and 2s is consistent with their having the
same type of central engine viewed at a different orientation. The nature of
the putative torus is becoming clearer; in particular we present evidence that
it is likely a clumpy medium. Mid-infrared correlations between tracers of star
formation and AGN ionizing luminosity reveal the starburst-AGN connection
implied by the black hole/bulge mass relation, however it is not yet clear if
this is due to feedback.
