The Democratic Republic of the Congo is renamed Zaire.

Zaire (, also UK: ), officially the Republic of Zaire (French: Rpublique du Zare, [epyblik dy zai]), was a Congolese state from 1971 to 1997 in Central Africa that was previously and is now again known as the Democratic Republic of the Congo. Zaire was, by area, the third-largest country in Africa (after Sudan and Algeria), and the 11th-largest country in the world. With a population of over 23 million inhabitants, Zaire was the most-populous officially Francophone country in Africa, as well as one of the most populous in Africa.

The country was a one-party totalitarian dictatorship, run by Mobutu Sese Seko and his ruling Popular Movement of the Revolution party. Zaire was established following Mobutu's seizure of power in a military coup in 1965, following five years of political upheaval following independence from Belgium known as the Congo Crisis. Zaire had a strongly centralist constitution, and foreign assets were nationalized. The period is sometimes referred to as the Second Congolese Republic.

A wider campaign of Authenticit, ridding the country of the influences from the colonial era of the Belgian Congo, was also launched under Mobutu's direction. Weakened by the termination of American support after the end of the Cold War, Mobutu was forced to declare a new republic in 1990 to cope with demands for change. By the time of its downfall, Zaire was characterised by widespread cronyism, corruption and economic mismanagement.

Zaire collapsed in the 1990s, amid the destabilization of the eastern parts of the country in the aftermath of the Rwandan genocide and growing ethnic violence. In 1996, Laurent-Dsir Kabila, the head of the Alliance of Democratic Forces for the Liberation of Congo (AFDL) militia, led a popular rebellion against Mobutu. With rebel forces successfully making gains westward, Mobutu fled the country, leaving Kabila's forces in charge as the country restored its name to the Democratic Republic of the Congo the following year, and he died less than four months later while in exile in Morocco.

The Democratic Republic of the Congo (pronunciation French: République démocratique du Congo (RDC) [kɔ̃ɡo]), also known as Congo-Kinshasa, DR Congo, the DRC, the DROC, or the Congo, and formerly Zaire, is a country in Central Africa. It is, by area, the second largest country in Africa (after Algeria), and the 11th-largest in the world. With a population of around 92 million, the Democratic Republic of the Congo is the most populous officially Francophone country in the world. It is a member of the United Nations, Non-Aligned Movement, African Union, COMESA, and the East African Community. Since 2015, the Eastern DR Congo has been the site of an ongoing military conflict in Kivu. The capital and largest city is Kinshasa, which is also the world's most populous Francophone city.

Centered on the Congo Basin, the territory of the DRC was first inhabited by Central African foragers around 90,000 years ago and was reached by the Bantu expansion about 3,000 years ago. In the west, the Kingdom of Kongo ruled around the mouth of the Congo River from the 14th to 19th centuries. In the northeast, center and east, the kingdoms of Azande, Luba and Lunda ruled from the 16th and 17th centuries to the 19th century.

In the 1870s, just before the onset of the Scramble for Africa, European exploration of the Congo Basin was carried out, first led by Henry Morton Stanley under the sponsorship of Leopold II of Belgium. Leopold formally acquired rights to the Congo territory at the Berlin Conference in 1885 and declared the land his private property, naming it the Congo Free State. During the Free State, his colonial military unit, the Force Publique, forced the local population to produce rubber. From 1885 to 1908, millions of Congolese people died as a consequence of disease and exploitation. In 1908, Leopold, despite his initial reluctance, ceded to Belgium the so-called Free State, which thus became known as the Belgian Congo.

Congo achieved independence from Belgium on 30 June 1960 under the name Republic of the Congo. Congolese nationalist Patrice Lumumba was elected the first Prime Minister, while Joseph Kasa-Vubu became the first President. During the Congo Crisis, Joseph-Désiré Mobutu, who later renamed himself Mobutu Sese Seko, officially came into power through a coup d'état and renamed the country Zaire in 1971. The country was run as a dictatorial one-party state, with his Popular Movement of the Revolution as the sole legal party. By the early 1990s, Mobutu's government began to weaken. Destabilisation in the east resulting from the 1994 Rwandan genocide led to a 1996 invasion led by Rwanda, which led to Mobutu's ousting in the First Congo War the following year.Laurent-Désiré Kabila then became the new president, reverting the country's name to the Democratic Republic of the Congo. Tensions between President Kabila and the Rwandan and Tutsi presence in the country led to the Second Congo War from 1998 to 2003. Ultimately, nine African countries and around twenty armed groups became involved in the war, which resulted in the deaths of 5.4 million people. The two wars devastated the country. Kabila was assassinated by one of his bodyguards on 16 January 2001 and was succeeded eight days later by his son Joseph, under whom human rights in the country remained poor and included frequent abuses such as forced disappearances, torture, arbitrary imprisonment and restrictions on civil liberties according to NGOs. Following the 2018 general election, in the country's first peaceful transition of power since independence, Kabila was succeeded as president by Félix Tshisekedi, who has served as president since.The Democratic Republic of the Congo is extremely rich in natural resources but has suffered from political instability, a lack of infrastructure, corruption, and centuries of both commercial and colonial extraction and exploitation with little widespread development. Besides the capital Kinshasa, the two next largest cities, Lubumbashi and Mbuji-Mayi, are both mining communities. The DRC's largest export is raw minerals, with China accepting over 50% of its exports in 2019. In 2019, DR Congo's level of human development was ranked 175th out of 189 countries by the Human Development Index. As of 2018, around 600,000 Congolese have fled to neighbouring countries from conflicts in the centre and east of the DRC. Two million children risk starvation, and the fighting has displaced 4.5 million people.
