  Starting from $E_{11}$ and the space-time translations we construct an
algebra that promotes the global $E_{11}$ symmetries to local ones, and
consider all its possible massive deformations. The Jacobi identities imply
that such deformations are uniquely determined by a single tensor that belongs
to the same representation of the internal symmetry group as the $D-1$ forms
specified by $E_{11}$. The non-linear realisation of the deformed algebra gives
the field strengths of the theory which are those of any possible gauged
maximal supergravity theory in any dimension. All the possible deformed
algebras are in one to one correspondence with all the possible massive maximal
supergravity theories. The hierarchy of fields inherent in the $E_{11}$
formulation plays an important role in the derivation. The tensor that
determines the deformation can be identified with the embedding tensor used
previously to parameterise gauged supergravities. Thus we provide a very
efficient, simple and unified derivation of the bosonic sector, and in the
absence of gravity, of all maximal gauged supergravities from $E_{11}$.
