A multinational state or a multinational union is a sovereign entity that comprises two or more nations or states. This contrasts with a nation state, where a single nation accounts for the bulk of the population. Depending on the definition of "nation" (which touches on ethnicity, language, and political identity), a multinational state is usually multicultural or multilingual, and is geographically composed of more than one country, eg Countries of the United Kingdom. Historical multinational states that have since split into multiple sovereign states include the Ottoman Empire, British India, Czechoslovakia, the Soviet Union, Yugoslavia and Austria-Hungary (a dual monarchy of two multinational states). Some analysts have described the European Union as a multinational state or a potential one. Types of countries Definition Many attempts have been made to define what a multinational state is. One complicating factor is that it is possible for members of a group that could be considered a nation to identify with two different nationalities simultaneously. As Ilan Peleg wrote in Democratizing the Hegemonic State: A state may also be a society, and a multiethnic society has people belonging to more than one ethnic group, in contrast to societies that are ethnically homogeneous. By some definitions of "society" and "homogeneous", virtually all contemporary national societies are multiethnic. The scholar David Welsh argued in 1993 that fewer than 20 of the 180 sovereign states then in existence were ethnically and nationally homogeneous, if a homogeneous state was defined as one in which minorities made up less than 5 percent of the population. Sujit Choudhry therefore argues that "[t]he age of the agriculturally homogeneous state, if ever there was one, is over". Modern multinational states Africa Most countries in Sub-Saharan Africa are former colonies and, as such, are not drawn along national lines, making them truly multinational states. Ghana There is no ethnic majority in Ghana. The plurality group, the Akan people, are a meta-ethnicity (that is, a collection of similar but distinct ethnicities). While Akan is the most-widely spoken language in Ghana, English is the official language of government Kenya Kenya is home to more than 70 ethnic groups, the most populous of which are the Kikuyu, at about 20 percent of the population. Together, the five largest groups—the Kikuyu, Luo, Luhya, Kamba, and Kalenjin—account for 70 percent of Kenyans. Nigeria The largest nation in Nigeria is the Hausa-Fulani, which accounts for 29 percent of the
