SUMMARY:The first Giga-years of the Milky Way halo and its satellites told 
 by RRLs
DESCRIPTION:The first Giga-years of the Milky Way halo and its satellites t
 old by RRLs\nDrs. Giuliana Fiorentino\n\nThe first Gigayears of our Galact
 ic halo can be probed by using ancient  stellar populations as traced by R
 R Lyrae stars. Today, with the  advancement in our knowledge of RR Lyrae p
 roperties belonging to the Halo and to Milky Way satellite systems (Globul
 ar clusters and dwarf galaxies) we are able to provide solid constraints o
 n the link between these stellar  systems. Here, we present some recent re
 sults concerning the Halo  formation by using a detailed evolutionary anal
 ysis of RR Lyrae stars for which chemical abundances are available.
