In this talk we study the analogue of tautological rings of fibre bundles in the context of fibrations with Poincare fibre, i.e. the ring of obtained by fibre integrating powers of the fibrewise Euler class. I will discuss this object and an approach to compute it via rational homotopy theory, as well as some interesting properties and applications.
