La Seguridad Social es una disciplina relativamente reciente, si se considera que la mayoría de los especialistas coinciden en que sus primeros antecedentes claros se remontan apenas al último tercio del siglo XIX, cuando Otto Von Bismarck promovió en Prusia las primeras leyes que crearon seguros sociales. Se consolidó de manera importante durante el siglo XX y particularmente en México con la expedición de la primera Ley del Seguro Social que entró en vigor en enero de 1943, la cual fue sustituida por la segunda que entró en vigor en 1973 y ésta a su vez por la actual que inició su vigencia en 1997, que por diversas razones es la más importante en México.
Social Security is a relatively recent discipline, considering that most specialists agree that its first clear history goes back to the last third of the 19th century, when Otto Von Bismarck promoted the first laws that created social insurance in Prussia. It was consolidated in an important way during the twentieth century and particularly in Mexico with the issuance of the first Social Security Law that came into force in January 1943, which was replaced by the second that came into force in 1973 and this in turn by the current one that began its validity in 1997, which for various reasons is the most important in Mexico. In this essay a panoramic synthesis of the content of this Law is developed, including the conceptual delimitation of the matter; the description of the current legal framework; as well as its normative structure and the specific content of the services and services provided in each of the insurances that are part of both the compulsory and voluntary schemes, in a language that is intended to be simple and that allows knowing the most important aspects of the Social Security Law in force in summary form despite its enormous complexity.
