Today our understanding of Nature is based on two pillars, the classical theory of General Relativity and the Standard Model of particle physics, each remarkably successful and predictive. However, the coalescence of a classical spacetime with the quantum nature of matter leads to severe inconsistencies which are at the heart of many open problems in modern physics. In constructing a quantum theory of gravity which cures these deficiencies one not only faces the problem that General Relativity is perturbatively non-renormalizable, but one also has to incorporate the fundamental requirement of Background Independence, expressing that no particular spacetime (such as Minkowski space) is singled out a priori. In this thesis we employ a non-per...
