Secular evolution of binaries driven by an external (tidal) potential is aclassic astrophysical problem. Tidal perturbations can arise due to an externalpoint mass, as in the Lidov-Kozai (LK) theory of hierarchical triples, or dueto an extended stellar system (e.g. galaxy or globular cluster) in which thebinary resides. For many applications, general-relativistic (GR) apsidalprecession is important, and has been accounted for in some LK calculations.Here we generalise and extend these studies by exploring in detail the effectof GR precession on (quadrupole-level) tidal evolution of binaries orbiting inarbitrary axisymmetric potentials (which includes LK theory as a special case).We study the (doubly-averaged) orbital dynamics for arbitrary strengths of GRand binary initial conditions and uncover entirely new phase space morphologieswith important implications for the binary orbital evolution. We also explorehow GR precession affects secular evolution of binary orbital elements when thebinary reaches high eccentricity ($e\to 1$) and delineate several differentdynamical regimes. Our results are applicable to a variety of astrophysicalsystems. In particular, they can be used to understand the high-eccentricitybehaviour of (cluster) tide-driven compact object mergers -- i.e. LIGO/Virgogravitational wave sources -- for which GR effects are crucial.
