Letter of credenceA letter of credence (Lettre de créance) is a formal diplomatic letter that designates a diplomat as ambassador to another sovereign state. Commonly known as diplomatic credentials, the letter is addressed from one head of state to another, asking them to give credence (créance) to the ambassador's claim of speaking for their country. The letter is presented personally by the ambassador-designate to the receiving head of state in a formal ceremony, marking the beginning of the ambassadorship.
LegationA legation was a diplomatic representative office of lower rank than an embassy. Where an embassy was headed by an ambassador, a legation was headed by a minister. Ambassadors outranked ministers and had precedence at official events. Legations were originally the most common form of diplomatic mission, but they fell out of favor after World War II and were upgraded to embassies. Through the 19th century and the early years of the 20th century, most diplomatic missions were legations.
Vienna Convention on Diplomatic RelationsThe Vienna Convention on Diplomatic Relations of 1961 is an international treaty that defines a framework for diplomatic relations between independent countries. Its aim is to facilitate "the development of friendly relations" among governments through a uniform set of practices and principles; most notably, it codifies the longstanding custom of diplomatic immunity, in which diplomatic missions are granted privileges that enable diplomats to perform their functions without fear of coercion or harassment by the host country.
Head of governmentThe head of government is the highest or the second-highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, autonomous region, or other government who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. In diplomacy, "head of government" is differentiated from "head of state" although in some countries, for example the United States, they are the same person.

Head of stateA head of state (or chief of state) is the public persona who officially embodies a state in its unity and legitimacy. Depending on the country's form of government and separation of powers, the head of state may be a ceremonial figurehead or concurrently the head of government and more (such as the president of the United States, who is also commander-in-chief of the United States Armed Forces). In a parliamentary system, such as the United Kingdom or India, the head of state usually has mostly ceremonial powers, with a separate head of government.
