A parliamentary system, or parliamentary democracy, is a form of government based on the fusion of powers. In this system the head of government (chief executive) derives their democratic legitimacy from their ability to command the support ("confidence") of a majority of the parliament, to which they are held accountable. This head of government is usually, but not always, distinct from a ceremonial head of state. This is in contrast to a presidential system, which features a president who is not fully accountable to the legislature, and cannot be replaced by a simple majority vote.

Countries with parliamentary systems may be constitutional monarchies, where a monarch is the head of state while the head of government is almost always a member of parliament, or parliamentary republics, where a mostly ceremonial president is the head of state while the head of government is from the legislature. In a few countries, the head of government is also head of state but is elected by the legislature. In bicameral parliaments, the head of government is generally, though not always, a member of the lower house.

International sanctions are political and economic decisions that are part of diplomatic efforts by countries, multilateral or regional organizations against states or organizations either to protect national security interests, or to protect international law, and defend against threats to international peace and security. These decisions principally include the temporary imposition on a target of economic, trade, diplomatic, cultural or other restrictions (sanctions measures) that are lifted when the motivating security concerns no longer apply, or when no new threats have arisen.

According to Chapter VII of the United Nations Charter, only the UN Security Council has a mandate by the international community to apply sanctions (Article 41) that must be complied with by all UN member states (Article 2,2). They serve as the international community's most powerful peaceful means to prevent threats to international peace and security or to settle them. Sanctions do not include the use of military force. However, if sanctions do not lead to the diplomatic settlement of a conflict, the use of force can be authorized by the Security Council separately under Article 42.

A congress is a formal meeting of the representatives of different countries, constituent states, organizations, trade unions, political parties, or other groups. The term originated in Late Middle English to denote an encounter (meeting of adversaries) during battle, from the Latin congressus.

Military ranks are a system of hierarchical relationships within armed forces, police, intelligence agencies and other institutions organized along military lines. Responsibility for personnel, equipment and missions grows with each advancement. The military rank system defines dominance, authority and responsibility within a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command is an important component for organized collective action.

Uniforms denote the bearer's rank by particular insignia affixed to the uniforms of a number of countries.

As time went on and military operations became larger and more complex, more ranks were created and the systems of ranking became more complex.
