Forming low-mass stars appear to be born with simple, dominantly axisymmetric, large-scale magnetic fields. Their magnetospheres transition to complex, multipolar, and dominantly non-axisymmetric, as they evolve across the H-R diagram towards the main sequence. I will discuss the evolution of stellar magnetism during the pre-main sequence phase and the implications this has for coronal X-ray emission. I will highlight some recent observations that may suggest that magnetospheric accretion during the star-disk interaction phase influences the magnetic topology of young stars.
