Abstract: The parallaxes from the second Gaia release (DR2) enable us to calibrate the RR Lyrae Period – KS and Period – WBV relations. An RR Lyrae sample of over 200 field stars with mv<12.m5 is constructed. We discuss the theoretical background to Period-Luminosity relations for RR Lyrae stars and study their impact on the distance scale for population II objects and derive the relation between MV and [Fe/H] as well as distances to selected Galactic Globular Clusters and the LMC.
