The theories within International Relations help us understand how other nations view the world and engage with one another. These theories create more of an understanding of how international systems work. To outsiders knowing nothing about international relations, this can be quite beneficial in order to become more informed. We are going to dive into 5 of the key theories in International Relations which include, Realism, Marxism, Liberalism, Constructivism, and Feminism.

Realism
The Realism theory is one of the two foundational theories, along with Liberalism, that all others were expanded upon.  Realism is based on the theory that all nations strive to develop their own power and whoever learns to gain and keep the most power will prosper while covering up achievements made by other nations.

Liberalism
The Liberalism theory as the second foundational theory, along with Realism, focuses on empowering and working alongside other nations. Instead of using force, Liberalism relies on creating a peaceful order within the world. The theory believes that working together to ensure the achievements of all nations, is more important than power over one another. This lends itself to the idea that Liberalism will further the interests of each nation.

Marxism
The Marxism theory puts a heavy focus on economic and materialistic characteristics within international relations. This theory emphasizes the needs of humans before private profit while working under a socialist regime.

Feminism
As you would have guessed, the Feminism theory deals directly with gender equality amongst different nations. Feminist policies have been put in place in other countries that have lead women to excel significantly within the country’s political climate. Feminism continues to be a leading concern among international affairs and politics across the nation.

Constructivism
The Constructivism theory in international relations is based on the belief that political affairs done internationally are made up of culture, values, social identities, and influential ideas. This theory believes that international relations are formed by a thought of which is believed by a social class or society.

International Relations theories give us a better understanding of how countries around the world work and what their particular culture and belief system is. Getting a degree in International Relations can work to help you fully grasp the different theories and policies taking place in different countries, but an overall understanding of these five theories can give the general public a look at what is happening all across the world.
