His study of Second Empire Paris and the events surrounding the Paris Commune in "Paris, Capital of Modernity", is undoubtedly his most elaborated historical-geographical work. The onset of US military action since 2001 has provoked a blistering critique – in "The New Imperialism" (2003) he argues that the war in Iraq allows US neo-conservatives to divert attention from the failures of capitalism 'at home'. His next work, "A Brief History of Neoliberalism" (2005), provides an historical examination of the theory and divergent practices of neoliberalism since the mid-1970s. This work conceptualises the neoliberalised global political economy as a system that benefits few at the expense of many, and which has resulted in the (re)creation of class distinction through what Harvey calls "accumulation by dispossession". His book "The Enigma of Capital" (2010) takes a long view of the contemporary economic crisis. Harvey explains how capitalism came to dominate the world and why it resulted in the financial crisis. He describes that the essence of capitalism is its amorality and lawlessness and to talk of a regulated, ethical capitalism is to make a fundamental error. A series of events linked to this book across London academic forums, such as the LSE, proved hugely popular and sparked a new interest in Harvey's work.
