List of historical unrecognized states

These lists of historical unrecognized or partially recognized states or governments give an overview of extinct geopolitical entities that wished to be recognized as sovereign states, but did not enjoy worldwide diplomatic recognition. The entries listed here had de facto control over their claimed territory and were self-governing with a desire for full independence; or if they lacked such control over their territory, they were recognized by at least one other recognized nation.

Criteria for inclusion

The criteria for inclusion in this list are similar to those of the list of states with limited recognition. To be included here, a polity must have claimed sovereignty, have not been recognized by at least one widely accepted state for a significant portion of its de facto existence, and either:

• had a population and an organized government with a capacity to enter into relations with other states; or
• had de facto control over a territory or a significant portion of the territory of an otherwise-recognized sovereign state

Africa

The total number of countries in the African continent varies due to the instability throughout the region. See the List of sovereign states and dependent territories in Africa article for a current list.

Great instability was created by graft under leaders in West Africa.

Many leaders marginalised ethnic groups and fanned ethnic conflicts (some of which had been exacerbated, or even created, by colonial rule) for political gain. In many countries, the military was perceived as being the only group that could effectively maintain order, and it ruled many nations in Africa during the 1970s and early 1980s. During the period from the early 1960s to the late 1980s, Africa had more than 70 coups and 13 presidential assassinations. Border and territorial disputes were also common, with the European-imposed borders of many nations being widely contested through armed conflicts.

A variety of other causes have been blamed for Africa's political instability, including Cold War conflicts between the United States and the Soviet Union, over-reliance on foreign aid, as well as the policies of the International Monetary Fund. When a country became independent for the first time, it would often align itself with one of the two superpowers in order to get support. Many countries in Northern Africa received Soviet military aid, while many in Central and Southern Africa were supported by the United States, France or both. The 1970s saw an escalation, as newly independent Angola and Mozambique aligned themselves with the Soviet Union, and the West and South Africa sought to contain Soviet influence by funding insurgency movements. There was a major famine in Ethiopia, when hundreds of thousands of people starved. Some claimed that Marxist/Soviet policies made the situation worse. The most devastating military conflict in modern independent Africa has been the Second Congo War; this conflict and its aftermath have killed an estimated 5.5 million people. Since 2003 there has been an ongoing conflict in Darfur which has become a humanitarian disaster. Another notable tragic event is the 1994 Rwandan Genocide in which an estimated 800,000 people were murdered. AIDS in post-colonial Africa has also been a prevalent issue.

In the 21st century, however, the number of armed conflicts in Africa has steadily declined. For instance, the civil war in Angola came to an end in 2002 after nearly 30 years. The improved stability and economic reforms have led to a great increase in foreign investment into many African nations, mainly from China, which has spurred quick economic growth in many countries, seemingly ending decades of stagnation and decline. Several African economies were among the world's fastest growing as of 2011 and that growth continues through 2019.

Shilluk Kingdom	15th century–1861	now part of South Sudan and Sudan	located along the left bank of the White Nile in what is now South Sudan and southern Sudan. Its capital and royal residence were in the town of Fashoda. According to Shilluk folk history and neighboring accounts, the kingdom was founded by Nyikang, who probably lived in the second half of the 15th century. A Nilotic people, the Shilluk managed to establish a centralized kingdom that reached its apogee in the late 18th and early 19th centuries, during the decline of the northern Funj Sultanate. In the 19th century, the Shilluk were affected by military assaults from the Ottoman Empire, resulting in the destruction of the kingdom in the early 1860s. The Shilluk king is currently not an independent political leader, but a traditional chieftain within the governments of South Sudan and Sudan. The current Shilluk king is Reth Kwongo Dak Padiet who ascended to the throne in 1993.

In a common front against the Ndwandwe, Shaka collected the remains of the Mthethwa and other regional tribes, and survived the first encounter of the Zulu Civil War with Zwide at the Battle of Gqokli Hill in 1818. In 1819, Zwide made another expedition against the Zulus, but Shaka again changed his tactics, letting the Ndwandwe army penetrate his territory and responding with guerrilla warfare. Shortage of supplies caused the Ndandwe to return home, but when they were crossing the river Mhlatuze in early 1820, their forces were split and defeated at the Battle of Mhlatuze River.

Provisional Revolutionary Government of Cibao	1857–1861	Now part of Cibao within the Dominican Republic (Spanish occupation of the Dominican Republic 1861–65)	On July 7, 1857, a popular civic-military movement broke out in Santiago with the purpose of overthrowing the government of the conservative president Buenaventura Báez. Immediately his spokesmen announced the integration of a revolutionary provisional government based in Santiago de los Caballeros. The Cibaenians launched a manifesto and expressed that they did it to "shake off the yoke of Mr. Báez's government that they do not know from now and declare themselves governed (until a congress elected by direct vote, constitute new powers) by a provisional revolutionary government, with its seat in the city of Santiago de los Caballeros." General José Desiderio Valverde was chosen as president of the anti-Báez and Santana provisional government, and the lawyer Benigno Filomeno Rojas as vice president. Both counted on the support of the tobacco producers and the Cibaenian trade. Among its first measures was the organization of an armed movement to march to the city of Santo Domingo, in order to overthrow President Buenaventura Báez, who was prepared to resist. The troops of the provisional revolutionary government of the Cibao were commanded by General Juan Luis Franco Bidó. In a few days they surrounded the city of Santo Domingo, thus initiating a civil war. The hostilities lasted almost a year. The groups in conflict fought with all the means at their disposal to emerge victorious, increasing violence and destruction in the country. The triumph of the revolution was resounding, Báez renounced power and traveled to exile, but the project would be frustrated, since the liberal thinking of the Cibaenians would be overshadowed by the military figure of General Pedro Santana, who returned to the Presidency of the Republic in 1858 and ignored the liberal constitution of Moca. In this way, the revolution of July 7, 1857, ended and the liberal constitution of Moca was annulled. Santana returned to govern with the Constitution of 1854 that guaranteed an authoritarian government. The following day, July 8, 1857, the "Dominican Republic" awoke with two government administrations: the provisional revolutionary government of Cibao and the "government" of President Buenaventura Báez. On September 25, the provisional revolutionary Government of the Cibao summoned the country to elect the deputies as of December 7, 1857. At that time the women and men of greater intellectual capacity in the Cibao wished to produce a constitution that would allow an authentically democratic and representative government by the people. "The new constitution was drafted in Moca and proclaimed on February 19, 1858." That day, the Constituent Assembly meeting in Moca proclaimed the liberal constitution that repealed the conservative one of December 1854. Established public freedoms and abolished the death penalty for political reasons and enshrined as rights the freedom of expression, free transit and freedom of peaceful assembly. He did not re-elect the president in succession and absolute respect for civil liberties without restrictions, including freedom of expression. established that the capital of the so-called republic, outside the city of Santiago de los Caballeros. The constitution of Moca consecrated free transit and freedom of peaceful assembly. That the government would be civil, republican, popular, representative, elective and responsible, and every citizen with the right to vote could do it directly and secretly, instead of the indirect way as established by the previous constitutions. In addition, the governors of provinces could not be the commanders of arms as it was available until February 19, 1858. Under the constitution of Moca, the municipal power was restored and the Armed Forces were declared obedient to the civil power, without powers to deliberate and with the function of defending national sovereignty, public order, as well as observing and complying with the constitution and laws. It was established on a transitory basis that the next constitutional government was chosen by the members of the constituent assembly, which they did on March 1, 1858. The constituent assembly of Moca was integrated by the provisional government of Santiago, chaired by General José Desiderio Valverde, who convened on September 25, 1857, to elect deputies from December 7, 1857. For the assembly, the most enlightened women and men of the country were chosen, whose thought corresponded to the movement proclaimed by the revolution of July 7, 1857, to overthrow the government of Buenaventura Báez, which they described as a dictatorship.

Kingdom of Fiji	1852–1871	Now recognized	Created by Fijian chief Seru Cakobau, who styled himself the king of Fiji. His claim was not recognized by the other chiefs of Fiji, leading to almost 20 years of warfare until Cakobau finally succeeded in unifying the island.
