I have reconstructed the first global star formation history
(SFH) of the Small Magellanic Cloud (SMC), based on our UBVI
photometric database of six million of its stars. The SFH
analysis was performed independently on >500 12 x 12 arcmin
subregions which tile the 4 x 4.5 degree region of our
photometric survey. The ensemble of these SFHs comprises a
detailed map of the past star formation activity throughout
the SMC.
Our reconstructed SFH exhibits several interesting features,
which we have begun to understand in the context of the
dynamical interaction history of the SMC and its neighbors,
the Large Magellanic Cloud and the Milky Way. The SMC is
providing a shining example of the idea that nearby galaxies
can provide unique insights into the general questions of
galaxy formation and evolution.
