Stead became an enthusiastic supporter of the peace movement, and of many other movements, popular and unpopular, in which he impressed the public generally as an extreme visionary, though his practical energy was recognised by a considerable circle of admirers and pupils. Stead was a pacifist and a campaigner for peace, who favoured a "United States of Europe" and a "High Court of Justice among the nations" (an early version of the United Nations), yet he also preferred the use of force in the defence of law. He extensively covered the Hague Peace Conferences of 1899 and 1907; for the latter he printed a daily paper during the four-month conference. He has a bust at the Peace Palace in The Hague. As a result of these activities, Stead was repeatedly nominated for the Nobel Peace Prize.
