We use a dynamical decomposition technique to isolate the stellar haloes of Milky Way-mass galaxies in the $100\\,{\\rm Mpc}$ EAGLE simulation and study their relationship to the merger histories of their hosts. We define the stellar halo as the stellar mass that is bound to the central subhalo but not associated with the disc or bulge components of a galaxy, and we quantify their merger histories using the most significant merger since $z=1$.
