Europeanisation (or Europeanization, see spelling differences) refers to a number of related phenomena and patterns of change: The process in which a notionally non-European subject (be it a culture, a language, a city or a nation) adopts a number of European features (often related to Westernization). Outside the social sciences, it commonly refers to the growth of a European continental identity or polity over and above national identities and polities on the continent. Europeanisation may also refer to the process through which European Union political and economic dynamics become part of the organisational logic of national politics and policy-making. Europeanisation in political science has been referred to very generally as 'becoming more European like'. More specifically than this, it has been defined in a number of ways. One of the earliest conceptualisations of the term is by Ladrech (1994, 69), who defines Europeanisation simply as ‘an incremental process of re-orienting the direction and shape of politics to the extent that EC political and economic dynamics become part of the organisational logic of national politics and policy making.’ This emphasises what is known as the 'top-down approach' to Europeanisation, in which change emanates from the impact of the Union on the national policy. The state is viewed as reactive to actions of the Union. Another definition that needs to be taken into account is from Radaelli, who describes Europeanisation as "a process involving a) construction, b) diffusion and c) institutionalisation of formal and informal rules, procedures, policy paradigms, styles, 'ways of doing things' and shared beliefs and norms which are first defined and consolidated in the EU policy process and then incorporated in the logic of domestic (national and subnational) discourse, political structures and public choices.
