Military alliances are formal agreements between two or more countries to support each other in the event of a conflict or attack. These alliances are typically formed to enhance the security and defense capabilities of the member countries, and to deter potential aggressors. Members of a military alliance often commit to providing military assistance, such as troops, equipment, or logistical support, to each other in times of need. Examples of military alliances include NATO (North Atlantic Treaty Organization) and the Warsaw Pact. **

Economic alliances are agreements between countries to cooperate on economic matters such as trade, investment, and monetary policy. These alliances are formed to promote economic growth, increase market access, and create a more stable and predictable economic environment. Examples of economic alliances include the European Union, NAFTA (North American Free Trade Agreement), and ASEAN (Association of Southeast Asian Nations). Through these alliances, member countries aim to strengthen their economies and enhance their competitiveness in the global market. **

Alliances are not accepted in Hearts of Iron IV (HoI4) because the game is designed to simulate the historical events and conflicts of World War II. Allowing alliances to be formed freely by the player would deviate from the historical accuracy and the strategic challenges that the game aims to provide. Instead, the game focuses on the historical alliances and rivalries that existed during the time period, and players are encouraged to navigate and manipulate these existing relationships to achieve their objectives. This adds an element of realism and historical authenticity to the gameplay experience. **

Economic alliances, such as trade agreements or regional economic blocs, can bring several advantages. They can promote economic growth by increasing trade and investment opportunities, leading to job creation and higher living standards. Additionally, they can help countries negotiate better trade deals and provide a platform for cooperation on economic issues. However, economic alliances also have disadvantages. They can lead to increased competition and pressure on domestic industries, potentially resulting in job losses or economic disruptions. There is also a risk of unequal benefits among member countries, with some nations gaining more than others. Furthermore, economic alliances can limit a country's sovereignty and decision-making autonomy in certain economic matters. **

The main alliances in the First World War were the Triple Entente and the Central Powers. The Triple Entente consisted of France, Russia, and the United Kingdom, and later included Italy, Japan, and the United States. The Central Powers included Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. These alliances formed as a result of various political and military agreements and treaties, and they played a significant role in shaping the course of the war. **

In Crusader Kings 3, you can view alliances by clicking on the character you are interested in and going to the "Alliances" tab in their character screen. This tab will show you all the current alliances that character has, as well as any potential new alliances you can form with them. You can also view your own alliances by clicking on your character portrait and going to the same "Alliances" tab. This allows you to easily keep track of your diplomatic relationships and alliances with other characters in the game. **

In Hearts of Iron 4, alliances can be created by improving relations with other countries through diplomacy, such as sending gifts, guaranteeing their independence, or offering to join their wars. Additionally, forming alliances can also be achieved through common ideologies or shared enemies. It is important to carefully consider the political landscape and strategic goals before forming alliances to ensure they are beneficial and align with your long-term objectives in the game. **
