What is the Meaning & Definition of literary movement

Literature and its history is studied from different perspectives. We often submit to authors within a certain genre: narrative, poetry and theatre. It also explores the literature according to the times or periods (the Spanish golden age, the Hispanic boom, etc). A different option is the knowledge of the literature through the analysis of the literary movements. A literary movement is formed by a set of contemporary authors that share some concerns (issues, style, ideology...). The term literary movement is often associated with the so-called ISMS. ISM is a suffix that means doctrine or tendency and is used in the field of art. There are many ISMS in the literature: realism, naturalism, Dadaism, surrealism, etc.
Both the idea of literary movement and the notion of ISM as doctrine act as synonymous terms. The literary movement has a specific name (with the suffix ISM or without) when a group of writers share a same time and a series of concerns. A good example is the romanticism. It arose as a reaction to the realism when a group of writers began to abandon the concerns and ideas of realism and incorporated a renewed spirit; with new themes, a more creative style and ideals with another dimension.
A literary movement itself can have its equivalent in other arts. Thus it happened also with romanticism, which manifested itself in painting or music. In this way, the romanticism expressed the feeling of an era and that expression went beyond a specific artistic manifestation.
The idea of literary movement is useful for sorting and understanding of literary works. It is a classification system which allows to understand the perpetrators within a cultural context. Classifications have certain problems in their interpretation. The problems manifest themselves when the critics and researchers of literature considered a literary movement has a new trend (spoken of modernism and postmodernism, realism and neorealism). The technical discussion of the specialists is typical of intellectuals and academics and usually not of interest to the public in general.
The concept of literary movement implies a clear reality. Each author belongs to his own time and in it there are values and shared interests, so it is natural that there is a common expressive course. This does not mean that all literary expression is within a movement, as there are authors that attached to an ISM, trend or movement.
