  In this paper we give, for the first time, a complete description of the
dynamics of tilted spatially homogeneous cosmologies of Bianchi type II. The
source is assumed to be a perfect fluid with equation of state $p = (\gamma -1)
\mu$, where $\gamma$ is a constant. We show that unless the perfect fluid is
stiff, the tilt destabilizes the Kasner solutions, leading to a Mixmaster-like
initial singularity, with the tilt being dynamically significant. At late times
the tilt becomes dynamically negligible unless the equation of state parameter
satisfies $\gamma > {10/7}$. We also find that the tilt does not destabilize
the flat FL model, with the result that the presence of tilt increases the
likelihood of intermediate isotropization.
