DESCRIPTION:The Reissner-Nordström black hole describes the gravitational
  and electromagnetic fields created by a spherically symmetric object gove
 rned by two parameters: its mass and electric charge. Generalizations of t
 his solution through non-linear electrodynamics and their non-abelian gene
 ralizations have received a considerable interest in the last decades. In 
 this talk I will give an overview of the current state of the topic and de
 scribe my own contributions to it. In particular\, I shall describe a gene
 ral procedure which allows to classify and qualitatively characterize the 
 whole family of non-linear electrodynamics defined as arbitrary functions 
 of the two field invariants and satisfying certain requirements for physic
 al consistence of the theories. Through this procedure it is possible to s
 tudy several features of the black holes including its metric structure an
 d thermodynamics without explicitly fixing the lagrangian density function
 . Some explicit examples are given. Finally I will describe applications o
 f this method to other interesting cases\, such as generalized non-abelian
  gauge fields\, and to other gravity theories such as the Lovelock one.\n\
