This book is devoted to a pedagogical introduction to supergravity from a practical perspective. As a particular feature of the book, the authors provide explicit details, which makes the computations easier to follow for the interested reader. Each chapter has summary tables, which contain the main results and, in addition, we have collected important or additional material in the appendix. In the first part of the book, the N=1 supergravity Lagrangian in four spacetime dimensions is derived. Closely following the reference of Wess and Bagger, we use the superspace approach. All steps, from the geometric principles of curved superspace to the field redefinition necessary to obtain a correctly normalised Lagrangian, are carefully analysed. Comparisons with other methods, such as conformal supergravity, are also given. In the second part of the book, we address more phenomenological aspects of supergravity such as supersymmetry breaking, no-scale supergravity, super-Higgs mechanism, etc. Finally, the relationship between supergravity and particle physics, and cosmology are analysed. Key Features: oAll technical details necessary to obtain N=1, D=4 supergravity are given in such a way that the interested reader can reproduce all the computations. oSome applications of supergravity are studied, for instance in relation with supergravity breaking, particles physics, etc. (which is not included in Wess & Bagger for instance) oEight appendices are given in order to illuminate the main text and many tables, summarizing important results, are collected throughout the book for an easy reading
