Although it does not border Zimbabwe, a part of less than 200 metres of the Zambezi River (essentially a small bulge in Botswana to achieve a Botswana/Zambia micro-border) separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek, and it is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU), and the Commonwealth of Nations.  - Charles André Joseph Marie de Gaulle (22 November 1890  9 November 1970) was a French general and statesman.

The metaphor derives from the carved figurehead at the prow of a sailing ship. Commonly cited figureheads include Queen Elizabeth II, who is Queen of sixteen Commonwealth realms and head of the Commonwealth, but has no power over the nations in which she is not head of state and does not exercise power in her own realms on her own initiative. Other figureheads are the Emperor of Japan, the King of Sweden, or presidents in majority of parliamentary republics, such as the President of India, President of Israel, President of Bangladesh, President of Greece, President of Germany, President of Pakistan (starting in 2010), and President of China (without CPC General Secretary and Chairman of CMC posts).  - Zimbabwe, officially the Republic of Zimbabwe, is a landlocked country located in southern Africa, between the Zambezi and Limpopo Rivers.

Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.  - Head of government is a generic term used for either the highest or second highest official in the executive branch of a sovereign state, a federated state, or a self-governing colony, (commonly referred to as countries, nations or nation-states) who often presides over a cabinet, a group of ministers or secretaries who lead executive departments. The term "head of government" is often differentiated from the term "head of state", (e.g. as in article 7 of the Vienna Convention on the Law of Treaties, article 1 of the Convention on the Prevention and Punishment of Crimes against Internationally Protected Persons, including Diplomatic Agents and the United Nations protocol list), as they may be separate positions, individuals, and/or roles depending on the country.  - Windhoek (; German: ""; ) is the capital and largest city of the Republic of Namibia.

The population of Windhoek in 2011 was 325,858, growing continually due to an influx from all over Namibia.  - The United Nations (UN) is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the United Nations is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict.  - A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch.
