text: Post–Cold War As the Cold War dwindled in 1991, interest in a federal world government was renewed. When the conflict ended by 1992, without the external assistance, many proxy wars petered out or ended by negotiated settlements. This kicked off a period in the 1990s of unprecedented international activism and an expansion of international institutions. According to the Human Security Report 2005, this was the first effective functioning of the United Nations as it was designed to operate.
  The most visible achievement of the world federalism movement during the 1990s is the Rome Statute of 1998, which led to the establishment of the International Criminal Court in 2002. In Europe, progress towards forming a federal union of European states gained much momentum, starting in 1952 as a trade deal between the German and French people led, in 1992, to the Maastricht Treaty that established the name and enlarged the agreement that the European Union is based upon. The EU expanded (1995, 2004, 2007, 2013) to encompass, in 2013, over half a billion people in 28 member states (27 after Brexit). Following the EU's example, other supranational unions were established, including the African Union in 2002, the Union of South American Nations in 2008, and the Eurasian Economic Union in 2015.
