Editing Democratic peace theory (section)

===Republican liberalism===
'''Republican liberalism''' is a variation of Democratic Peace Theory which claims that [[Liberal democracy|liberal]] and republican democracies will rarely go to war with each other. It argues that these governments are more peaceful than non-democracies and will avoid conflict when possible. According to Micheal Doyle, there are three main reasons for this: Democracies tend to have similar domestic political cultures, they share common morals, and their economic systems are interdependent.<ref>Jackson, Robert and Georg Sorensen (2006), ''Introduction to International Relations: theories and approaches'', Oxford, OUP, 3rd ed, p. 111</ref><ref>{{Cite journal|last=Doyle|first=Michael W.|date=1986|title=Liberalism and World Politics|url=https://www.jstor.org/stable/1960861|journal=Johns Hopkins University|volume=80|issue=4 |pages=1151–1169|doi=10.2307/1960861 |jstor=1960861 |s2cid=145154148 |url-access=subscription}}</ref> Liberal democracies (republics) that trade with each other, are economically dependent on one another and therefore, will always attempt to maintain diplomatic relations as to not disrupt their economies.

[[Liberalism (international relations)|Liberalism]], as an overarching theory, holds that diplomacy and cooperation is the most effective way to avoid war and maintain peace.<ref>{{Cite web|date=2018-02-18|title=Introducing Liberalism in International Relations Theory|url=https://www.e-ir.info/2018/02/18/introducing-liberalism-in-international-relations-theory/|access-date=2022-01-17|website=E-International Relations|language=en-US}}</ref> This is contrasting to the theory of [[Realism (international relations)|realism]], which states that conflict will always be recurrent in the international system, whether due to human nature or the anarchic international system.<ref>{{Cite web|date=2011-07-02|title=Realism and Liberalism in International Relations|url=https://www.e-ir.info/2011/07/02/realism-and-liberalism-in-modern-international-relations/|access-date=2022-01-17|website=E-International Relations|language=en-US}}</ref>

The concept of Republican liberalism is thought to have initially originated from [[Immanuel Kant]]'s book "[[Perpetual Peace: A Philosophical Sketch]]" (1795). The term "Perpetual Peace" refers to the permanent establishment of peace, and was made notorious by the book. Democratic peace, commercial peace and institutional peace were all advanced in the book as well. It takes a rather utopian view, that humanities' desire for peace will out compete humanities' desire for war.<ref name="Immanuel Kant, Perpetual Peace">{{Cite web|title=Immanuel Kant, "Perpetual Peace"|url=https://www.mtholyoke.edu/acad/intrel/kant/kant1.htm|access-date=2022-01-17|website=www.mtholyoke.edu|archive-date=September 26, 2019|archive-url=https://web.archive.org/web/20190926102047/https://www.mtholyoke.edu/acad/intrel/kant/kant1.htm|url-status=dead}}</ref>
