The dominant ideological force shaping western political thought, identified with western civilization itself
Liberal ideas and theories had a considerable impact on the discipline of international relations as it took shape following WWI
Liberal ideas drew on a much older tradition of 'idealist' theorizing which dates back to the Middle Ages and the ideas of early 'just war' thinkers such as Thomas Aquinas
Liberalism was marginalized during the early post -1945 period due to the failure of the liberal inspired Versailles Settlement and the ascendancy of realist thought
Liberal ideas nevertheless attracted growing attention from the 1970s onwards, often in the form of so-called neoliberalism
The end of the Cold War, the growing impact of globalization and a new wave of democratization in the 1990s each gave liberal theory additional impetus
Liberalism Theory is in part a reaction to realism, but also a response to a number of developments in the latter half of the 20th century that could not be explained by realism
Decline in conflict
The number of deaths in battle had fallen to less than 10,000 in 2006 compared with 600,000 in 1951
The nature of conflict also had changed, from predominantly inter-stateconflict (war between states) to intra-state conflict, or civilwar
Rise in democracy
By 2006, over half of all countries had become democracies
Democracies tend to be less aggressive than authoritarian regimes
According to democratic peace theory, no two democracies have ever been to war with each other
Since 2010 however there has been a reversal of democracy in Hungary, Burma, Russia and China, with these countries becoming more authoritarian and nationalist
Growth in world trade
Worldwide exports were worth $629 million in 1960, by 2010 they were worth $30 trillion
States are becoming increasingly interdependent, which is thought to reduce the potential for conflict between them
States will not risk conflict if it jeopardises the sale of exports and the supply of importedgoods
However, the policies of Donald Trump saw a return to some protectionistpolicies which restricted free trade with China
Beliefs of liberalism
Nation States are increasingly linked by many organisations, from trade like the WTO or militarily like NATO or diplomatic like the UN
International law is desirable
A state's primary aim should not merely be to become more powerful, particularly not at the expense of other states
There is mutual benefit in states cooperating and working together on matters such as security, trade and development
Democracy plays a key role in keeping states safe and peaceful
International trade binds states together in commoninterests, making them more dependent on each other and reducing the likelihood of conflict
the state has an important role to play in protecting individual rights but it must be limited by law so as not to infringe on those rights
liberalism is the belief that people are rational, self-interested individuals who will act to maximise their own interests
liberals believe that the state should intervene only when there is market failure or where there is a clear public good which cannot be provided through private enterprise

Liberals believe that the state exists to protect individualfreedom and liberty
liberals argue that internationalinstitutions promote cooperation among nations and prevent conflicts
liberals support the idea of global governance whereby decisions affecting people worldwide are made collectively by representatives of different nation states
Liberals argue that the state should only intervene when necessary to preventharm to others
Liberals argue that the state should protect individual freedom and liberty, including civil liberties and humanrights
The state should promote equality of opportunity rather than equality of outcome

The state should ensure that all citizens have equal opportunities to succeed regardless of their background
Liberals support international cooperation and globalisation because they see benefits in terms of economic growth and increased prosperity.
The state should have a minimal role in society and should limit its intervention into economic affairs
