This is so because that State, in charge of governing a certain population, always needs to have some kind of body or entity that records very diverse data, even some that nowadays are no longer recorded due to lack of utility.
However, it is not until recently, after the French Revolution perhaps and the loss of strength of religion in the 19th century as an important and even central part of a State, that the civil registry is established as a very important section for the administration. public. It is in this century when most of the states of the world began to remove the fueros and the power that the Church maintained over these aspects of social life such as marriages, births and deaths to give it a secular value and to make all these issues they will come under the power of the State and not of the Church or religion.
Today, civil registries are very important because they allow the fulfillment of a myriad of procedures and actions that did not exist before or that were not recognized by the Church.
Marriages, the annotations of newborns recognized by their parents, are some of the most common procedures carried out in these establishments, as we already indicated above.
