Super-massive blackholes at the centres of galaxies play an important role in regulating the growth and evolution of galaxies. They can drive high velocity outflows in the forms of wide-angled luminosity pressure driven winds or collimated relativistic jets. Although originating from a small central nuclear region, these outflows can have a galaxy-wide effect, which can regulate the star-formation rate of the host and its mass budget. In this talk I will present an overview of the various ways in which the blackhole can affect the host galaxy and beyond. I will present the results of our simulations which show how relativistic jets from the supermassive blackholes interact with gas both inside the galaxy and its environment. Finally, I will discuss the implications of such jet 'feedback' on the morphology and kinematics of the galaxy, its long term evolution and implications for observable signatures over wide range of wavelengths: from radio to X-ray bands.
