A revolution is a radical, deep and permanent change, with respect to the pre-existing order, a confrontation without return between two opposing interests, in a particular geographical place and, generally, it is carried out by a group of people who have the support of the rest of the people, who, already tired and fed up with the prevailing domination, offer them their moral support and accompaniment; if necessary, the same, if not given "by the good ones", can be achieved through the use of force and arms.
The revolution can occur simultaneously in several areas, such as being religious, military, cultural, political, economic or occur in one and then, over time, infect the rest with the spirit of change. Meanwhile, its characteristic and most recognizable feature is that of leaving transcendental consequences that will forever modify the normal course that things had until the moment that it occurred.. Even while some revolutions are focal and generate repercussions in the local environment, as has happened with many political, religious or ethnic movements in the third world, others revolutionary facts they can start in a localized way and then lead to their dissemination by other peoples or nations. Thus, the revolution that gave rise to American independence constituted an engine for the independence feat of the nations of Latin America. In the same way, the revolution of 1848 in Europe had its epicenter in Paris, but it spread rapidly towards Germany or Italy, to give rise to the true formation of a modern state in those countries. In recent times, it is easy to recognize that the revolutionary outbreaks in the Arab nations of North Africa started small hotspots in Tunis or Cairo, finally ending with the removal of numerous local governments.
It is worth noting that the history of humanity has registered three revolutions that due to their consequences, each one in its specific field, have, as I said before, changed the course of the history of the planet as a whole.
The french revolution because it was precisely a political movement that took place in France during the eighteenth century, in which they struggled to replace the prevailing form of government up to that time, which was the monarchy, by another, absolutely and radically opposite, that advocated a more wide and less closed. Such has been the magnitude of the revolution of 1789 that it is considered the starting point of a new chronological era, called the Contemporary Age.
Meanwhile, as an example of social revolution, the bourgeois revolution that also occurred at the same historical moment of the French Revolution and that supposed the displacement of the clergy and the nobility from the place of the ruling class that they held, for that of the bourgeoisie that completely changed the rules and the conception of the economy. Liberalism as an economic system managed to establish itself among the inhabitants of the country, with the birth of what today we call "middle strata" or middle class, to lay the foundations of what would evolve towards modern capitalism.
And the last, essentially economic root, but no less important and decisive than the previous ones, was the industrial Revolution that brought the solution of new techniques, energy sources, new machinery, means of transportation, the appearance of the first factories, among others, all of this put at the service of business growth and expansion. Although some deleterious consequences of this revolution were observed, such as the initial loss of jobs in pursuit of the greater use of machinery, the large production triggered by these changes generated new job opportunities in a short time, to give rise to a source of access to the activity and improve people's quality of life.
You may wonder if the explosion and diffusion of modern technology does not constitute a fourth revolution of world proportions ... it will be time and history that will allow us to define such a statement in a few decades ...
