Abstract :
Intrinsically compact extragalactic radio sources, with radio structures still within their host galaxies, are believed to represent the first stages in the evolution of extended radio galaxies. According to theoretical predictions, a significant fraction of the total radiative power of young radio sources is released in the high-energy domain by the AGN but also by the jets, hotspots and lobes. The X-ray emission should also trace the interactions of the radio source with its environment. In this talk I will review the status of the observations of young radio sources in the high-energy band, from X-to-gamma-rays, and discuss the implications for the physics of the early stages of the radio galaxy evolution and the feedback with the host galaxy.
