The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, a federal district, and various overseas extraterritorial jurisdictions. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the US mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
Political geography is the field of human geography that is concerned with the study of both the spatially uneven outcomes of political processes and the ways in which political processes are themselves affected by spatial structures. Conventionally political geography adopts a three-scale structure for the purposes of analysis with the study of the state at the centre, above this is the study of international relations (or geopolitics), and below it is the study of localities. The primary concerns of the sub-discipline can be summarised as the inter-relationships between people, state, and territory.
"Political geography in essence builds a country economy" The origins of political geography lie in the origins of human geography itself and the early practitioners were concerned mainly with the military and political consequences of the relationships between physical geography, state territories, and state power. In particular there was a close association with regional geography, with its focus on the unique characteristics of regions, and environmental determinism with its emphasis on the influence of the physical environment on human activities. This association found expression in the work of the German geographer Friedrich Ratzel who, in 1897 in his book Politische Geographie, developed the concept of Lebensraum (living space) which explicitly linked the cultural growth of a nation with territorial expansion, and which was later used to provide academic legitimation for the imperialist expansion of the German Third Reich in the 1930s.
There is a small community of Nigerians in the Netherlands, which began to grow in the late 1980s.
The earliest Nigerian asylum-seekers came to the Netherlands in 1987. As of 2006, the primary modes of migration of Nigerians are for marriage, work or study. Many of the Nigerians in the Netherlands for training are employees of Royal Dutch Shell. There is also some circular migration between Nigerians in the United Kingdom and in the Netherlands. One study, based on the cohort arriving in 1998, estimated that 25% of Nigerians who arrive in the Netherlands leave after four years. Nigerians point to the relative difficulty of finding work or starting businesses as a major driver for onward migration to the United Kingdom.
International relations (IR) is the study of relationships among countries, the roles of sovereign states, inter-governmental organizations (IGO), international non-governmental organizations (INGO), non-governmental organizations (NGO), and multinational corporations (MNC). International relations is an academic and a public policy field, and so can be positive and normative, because it analyzes and formulates the foreign policy of a given State. As political activity, international relations dates from the time of the Greek historian Thucydides (ca. 460–395 BC), and, in the early 20th century, became a discrete academic field (No. 5901 in the 4-digit UNESCO Nomenclature) within political science. However, International Relations is an interdisciplinary field of study.
Besides political science, the field of International Relations draws intellectual materials from the fields technology and engineering, economics, history, and international law, philosophy, geography, and social work, sociology, anthropology, and criminology, psychology and gender studies, cultural studies and culturology. The scope of International Relations comprehends globalization, state sovereignty, and international security, ecological sustainability, nuclear proliferation, and nationalism, economic development and global finance, terrorism and organized crime, human security, foreign interventionism, and human rights.
The Economic Community of West African States (ECOWAS; French: Communauté économique des États de l'Afrique de l'Ouest, CEDEAO) is a regional group of fifteen West African countries. Founded on 28 May 1975, with the signing of the Treaty of Lagos, its mission is to promote economic integration across the region.
Considered one of the pillars of the African Economic Community, the organization was founded in order to achieve "collective self-sufficiency" for its member states by creating a single large trading bloc through an economic and trading union. It also serves as a peacekeeping force in the region. The organization operates officially in three co-equal languages—French, English, and Portuguese.
