  The terminological use of "nations", "sovereignty" and associated concepts were significantly refined with the writing by Hugo Grotius of De jure belli ac pacis in the early 17th century. Living in the times of the Eighty Years' War between Spain and the Netherlands and the Thirty Years' War between Catholic and Protestant European nations, Grotius was deeply concerned with matters of conflicts between nations in the context of oppositions stemming from religious differences. The word nation was also applied before 1800 in Europe in reference to the inhabitants of a country as well as to collective identities that could include shared history, law, language, political rights, religion and traditions, in a sense more akin to the modern conception.
  
  Nationalism as derived from the noun designating 'nations' is a newer word; in the English language, dating to around 1798. The term gained wider prominence in the 19th century. The term increasingly became negative in its connotations after 1914. Glenda Sluga notes that "The twentieth century, a time of profound disillusionment with nationalism, was also the great age of globalism."
  
  Academics define nationalism as a political principle that holds that the nation and state should be congruent. According to Lisa Weeden, nationalist ideology presumes that "the people" and the state are congruent.
