 rgest gravitationally-bound structures in the Universe\, are superb labora
 tories for studying the baryon cycle that governs the evolution of all gal
 axies. The outer boundary of a galaxy's circumgalactic medium (CGM) should
  be the most sensitive probe of inflowing and outflowing material\, but it
  is difficult to observe. Only in galaxy clusters\, where the CGM gets hot
  enough to glow in X-rays\, can the entire baryon cycle be observed – fr
 om the rapid cooling of the intracluster medium that contributes to the CG
 M and level of star formation in the central galaxy\, to the eventual feed
 ing and triggering of feedback from the largest supermassive black holes (
 SMBHs) residing in them. This cooling and subsequent feedback from these a
 ctive galactic nuclei (AGN) is the primary driver of the baryon cycle and 
 evolution of the largest\, central cluster galaxies\, quenching their expe
 cted levels of cooling and star formation by up to two orders of magnitude
 . In this thesis\, I investigate how the AGN feedback cycle behaved in the
  early universe\, where studies of this kind have not been possible until 
 just recently. Using multiwavelength observations from radio to optical an
 d X-ray\, I study a unique\, representative sample of galaxy clusters and 
 their central galaxies and SMBHs spanning almost 10 Gyr of cosmic evolutio
 n. By studying how the largest galaxies and black holes in the universe co
 -evolve under extreme and chaotic environments\, we can gain a great deal 
 of insight into how the universe we see around us today came to be.
