A tradition is a belief or behavior passed down within a group or society with symbolic meaning or special significance with origins in the past. Common examples include holidays or impractical but socially meaningful clothes (like lawyer wigs or military officer-spurs), but the idea has also been applied to social norms such as greetings. Traditions can persist and evolve for thousands of years—the word "tradition" itself derives from the Latin tradere or traderer literally meaning to transmit, to hand over, to give for safekeeping. While it is commonly assumed that traditions have ancient history, many traditions have been invented on purpose, whether that be political or cultural, over short periods of time. Certain scholarly fields, such as anthropology and biology, have adapted the term "tradition," defining it more precisely than its conventional use in order to facilitate scholarly discourse.
The concept of tradition, as the notion of holding on to a previous time, is also found in political and philosophical discourse. For example, it's the basis of the political concept of traditionalism, and also strands of many world religions including traditional Roman Catholicism. In artistic contexts, tradition is used to decide the correct display of an art form. For example, in the performance of traditional genres (such as traditional dance), adherence to guidelines dictating how an art form should be composed are given greater importance than the performer's own preferences. A number of factors can exacerbate the loss of tradition, including industrialization, globalization, and the assimilation or marginalization of specific cultural groups. In response to this, tradition-preservation attempts have now been started in many countries around the world, focusing on aspects such as traditional languages. Tradition is usually contrasted with the goal of modernity and should be differentiated from customs, conventions, laws, norms, routines, rules and similar concepts.
