George Modelski devised a cyclical theory of world leadership. Each cycle has a duration of about 100 years and a new hegemonic power appears each time.
The five world leaders Portugal 1492–1580; in the
Age of Discovery The
Netherlands 1580–1688; beginning with the
Eighty Years' War, 1579-1588 United Kingdom (1) 1688–1792; beginning with the wars of
Louis XIV United Kingdom (2) 1792–1914; beginning with the
French Revolution and the
Napoleonic Wars The
United States 1914 to (predicted) 2030; beginning with
World War I and
World War II.
The four phases of the cycle 1, Global War, which a) involves almost all global powers, b) is 'characteristically naval' c) is caused by a system breakdown, d) is extremely lethal, e) results in a new global leader, capable of tackling global problems. The war is a 'decision process' analogous to a national election. The emerging global power typically enjoys a 'good war' with undamaged domestic infrastructure and a booming economy. The
Thirty Years War, though lasting and destructive, was not a 'global war' 2, World Power, which lasts for 'about one generation'. The new incumbent power 'prioritises global problems', mobilises a coalition, is decisive and innovative. For example, the UK after 1815 acted against the
transatlantic slave trade and led the
Congress system; the US after 1945 co-founded the
UN, the
IMF,
GATT, and the
Bretton Woods system. Pre-modern communities become dependent on the hegemonic power 3, Delegitimation. This phase can last for 20–27 years; the hegemonic power falters, as rival powers assert new
nationalistic policies. 4, Deconcentration. The hegemony's problem-solving capacity declines. It yields to a
multipolar order of warring rivals. Pre-modern communities become less dependent.
The role of the 'challenger' In the deconcentration phase a rival state or challenger, isolated and fearing encirclement , appears. Spain challenged Portugal;
Louis XIV and France challenged the Netherlands;
Napoleon Bonaparte sought to bring down the UK;
Germany under
Kaiser Wilhelm II and
Hitler brought an end to British hegemony for a second time. Writing in 1987, Modelski forecast that the
USSR would challenge American power from 2030, in a new global war.
Causes 1, Modelski writes, 'a similar more modest process may have occurred in Italy from 1000-1500 which then grew from a regional to a world level'. A similar regional cycle may have been present in China since 1,000, but ended with the death of
Cheng Ho in 1435. 2, The cycle is driven by generational change. In the Global War phase of 25–30 years, world order under a hegemon is preferred but unavailable; in the World Power phase, order is both preferred and available; in the 3rd phase, Delegitimation, order is present but unpopular; in phase 4, Deconcentration, order is both unwanted and unavailable, leading to further disputes and a new global war.
Origins and evolution According to Modelski, the cycle originated in about 1493 through a) the decline of Venetian naval power, b) Chinese abandonment of naval exploration, and c) discovery of sea routes to India and the Americas. It has developed in parallel with the growth of the nation-state, political parties, command of the sea, and 'dependency of pre-modern communities'. The system is flawed, lacking in coherence or solidarity; it also fails to address the
North-South divide.
Function Modelski wrote that the cycle is a 'learning process' and a 'motor of modernity', providing leadership on a global scale. The cycle ushers in new waves of innovation in orderly fashion. Awareness of the cycle provides a balanced perspective, and a counter to the widespread belief in global anarchy.
Forecasts Modelski speculates that US deconcentration might be replaced by a power based in the 'Pacific rim' or by an explicit coalition of nations, as 'co-operation is urgently required in respect of nuclear weapons'. It is possible for the US to become world leader a second time, as Britain did in the 19th century.
Critical response Modelski 'dismisses the idea that international relations are anarchic'. His research, influenced by
Immanuel Wallerstein, was 'measured in decades... a major achievement' says
Peter J. Taylor Colin Flint saw several flaws in the argument. It is deterministic, incapable of prediction; 'Portugal's 16th century history does not determine the US's 21st century future.' Modelski took a state-centric view which focused on rich countries and ignored the
Global South. Flint also questions whether naval power is still relevant in a time of cruise missiles, satellites and drones. Chinese leaders reject the idea of hegemony, and use the word as an insult.
Joshua S Goldstein says however that long cycles are not mechanistic or deterministic, but 'evolutionary and dynamic' and therefore do have predictive power. ==Books==
