Liberalism and democracy are closely linked together in international politics. They have a central link that brings out the notion of democratic peace. Today, much of Latin America and the European Union practice democracy. The chances of these nations engaging in armed conflict are very slim by today's standards. Liberalism promotes the idea of ​​human security and equality, and democracy reinforces that idea in the political framework of government bodies and their higher authorities. Liberalism leads to democracy which promotes democratic peace by preventing conflicts between nations. This article will examine how liberalism leads to democratic peace through the process of creating democracy. Liberalism in the sense of a political philosophy was created on the ideas of equality and freedom for all. Fundamentally liberalism deals with the concept of how individuals in political communities are able to maximize their own freedom without violating the rights of other individuals. The liberalist view of politics is that a legitimate government is necessary to protect the rights of individuals from being harmed by others. Liberalism also ensures the existence of a higher authority that protects the freedoms and rights of individuals while ensuring the legitimacy of the government. Liberalism is the founding basis of much of the government policies and constitution of the Western world. Liberalism ensures tolerance and promotes acceptance between human beings and their differences. Furthermore, liberalism then leads to democracy, which is a form of government in which all eligible citizens participate equally. This can be done directly or through elected representatives. Democracy includes racial, religious, ethnic, social issues and... at the heart of the card... a voice and a choice. They have a sense of being safe and free, something that can only be achieved through national security. Democracies also share similar political beliefs and ideologies that prevent them from engaging in war if a conflict occurs. Democratic peace theory states that democratic countries do not wage interstate wars against each other. This theory has been proven true time and time again throughout history. There has never been a case where an independent democratic country has launched a war against another democratic regime. So, surely, when it comes to resolving conflicts through war, regime type matters, as democratic states are 99% less likely to engage in a fight with autocracies and 100% less likely to declare war on other democrats. Democracy prevents conflicts at all levels of human interactions.
