Abstract: I will summarize the work of the last few years, culminating at covariant Lagrangian formulation of arbitrary abelian interactions of chiral p-forms and democratic (treating electric and magnetic degrees of freedom on equal footing) formulation of abelian interactions of arbitrary p-forms in arbitrary dimensions. This includes manifestly covariant and SO(2) duality invariant Lagrangians of all duality-symmetric electrodynamics in 3+1 dimensions and democratic type II Supergravities in 10d. I will also demonstrate a derivation for these Lagrangians from simple topological theories in one higher dimension.
