Correlation-driven metal-insulator transitions are typically coupled strongly both to local (octahedral distortion) and long wavelength (strain) lattice distortions. I present a theory of the intertwined electronic and lattice transitions in correlated materials, and show how it accounts for phenomena ranging from the interplay between nematic and magnetic ordering in pnictide superconductors, to the strain and current dependence of the metal insulator transitions in Ca2RuO4 and Ca3Ru2O7 and superlattice effects in the rare earth nickelates.
