Abstract
A new approach to integrability of affine Toda field theories and closely related to them KdV hierarchies is proposed. The flows of a hierarchy are explicity identified with infinitesimal action of the principal abelian subalgebra of the corresponding affine Kac-Moody algebra on a homogeneous space.
