Leopold II of Belgium in the context of "DRC"

In the social sciences, social structure is the aggregate of patterned social arrangements in society that are both emergent from and determinant of the actions of individuals. Likewise, society is believed to be grouped into structurally related groups or sets of roles, with different functions, meanings, or purposes. Examples of social structure include family, religion, law, economy, and class. It contrasts with "social system", which refers to the parent structure in which these various structures are embedded. Thus, social structures significantly influence larger systems, such as economic systems, legal systems, political systems, cultural systems, etc. Social structure can also be said to be the framework upon which a society is established. It determines the norms and patterns of relations between the various institutions of the society.

Since the 1920s, the term has been in general use in social science, especially as a variable whose sub-components needed to be distinguished in relationship to other sociological variables, as well as in academic literature, as result of the rising influence of structuralism. The concept of "social stratification", for instance, uses the idea of social structure to explain that most societies are separated into different strata (levels), guided (if only partially) by the underlying structures in the social system. There are three conditions for a social class to be steady, that of class cohesiveness, the self-consciousness of classes, and the self-awareness of one's own class. It is also important in the modern study of organizations, as an organization's structure may determine its flexibility, capacity to change, and success. In this sense, structure is an important issue for management.

The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo, or more infrequently Zaire (its official name from 1971 to 1997), is a country in Central Africa. By land area, it is the second-largest country in Africa and the 11th-largest in the world. With a population of around 112 million, the DR Congo is the fourth-most populous in Africa and the most populous nominally Francophone country in the world. French is the official and most widely spoken language, though there are over 200 indigenous languages. The national capital and largest city is Kinshasa, which is also the economic center. The country is bordered by the Republic of the Congo, the Cabinda exclave of Angola, and the South Atlantic Ocean to the west; the Central African Republic and South Sudan to the north; Uganda, Rwanda, Burundi, and Tanzania (across Lake Tanganyika) to the east; and Zambia and Angola to the south. Centered on the Congo Basin, most of the country's terrain is covered by dense rainforests and is crossed by many rivers, while the east and southeast are mountainous.

The territory of the Congo was first inhabited by Central African foragers around 90,000 years ago and was settled in the Bantu expansion about 2,000 to 3,000 years ago. In the west, the Kingdom of Kongo ruled around the mouth of the Congo River from the 14th to the 19th century. In the center and east, the empires of Mwene Muji, Luba, and Lunda ruled between the 15th and 19th centuries. These kingdoms were broken up by Europeans during the colonization of the Congo Basin. King Leopold II of Belgium acquired rights to the Congo territory in 1885 and called it the Congo Free State. In 1908, Leopold ceded the territory after international pressure in response to widespread atrocities, and it became a Belgian colony. Congo achieved independence from Belgium in 1960 and was immediately confronted by a series of secessionist movements, the assassination of Prime Minister Patrice Lumumba, and the seizure of power by Mobutu Sese Seko in 1965. Mobutu renamed the country Zaire in 1971 and imposed a personalist dictatorship.

Belgium controlled several territories and concessions during the colonial era, principally the Belgian Congo (modern DR Congo) from 1908 to 1960, Ruanda-Urundi (modern Rwanda and Burundi) from 1922 to 1962, and Lado Enclave (modern Central Equatoria province in South Sudan) from 1894 to 1910. It also had small concessions in Guatemala (1843–1854) and Belgian concession of Tianjin in China (1902–1931) and was a co-administrator of the Tangier International Zone in Morocco.

Roughly 98% of Belgium's overseas territory was just one colony (about 76 times larger than Belgium itself) – known as the Belgian Congo. The colony was founded in 1908 following the transfer of sovereignty from the Congo Free State, which was the personal property of Belgium's king, Leopold II. The violence used by Free State officials against indigenous Congolese and the ruthless system of economic extraction had led to intense diplomatic pressure on Belgium to take official control of the country. Belgian rule in the Congo was based on the "colonial trinity" (trinité coloniale) of state, missionary and private company interests. During the 1940s and 1950s, the Congo experienced extensive urbanization and the administration aimed to make it into a "model colony". As the result of a widespread and increasingly radical pro-independence movement, the Congo achieved independence, as the Republic of Congo-Léopoldville in 1960.

Sint-Petrus-en-Pauluskerk (Church of Saint Peter and Saint Paul) is a Roman Catholic church in Ostend, Belgium. The neo-Gothic building was constructed on the ashes of a previous church that occupied the site. King Leopold II enthusiastically supported a plan to build a new and more magnificent church. Construction started in 1899 and was completed and consecrated by Bishop Waffelaert on 31 August 1908. Its stained glass windows were destroyed during the two World Wars and were replaced by Michiel Martens. The church is 70 metres (230 ft) long and 30 metres (98 ft) wide. Its spires are 72 metres (236 ft) high.

The church was built in the neo-Gothic style according to plans by the architect Louis Delacenserie, who based his design on the Gothic Cologne Cathedral and the neo-Gothic Votivkirche in Vienna.

Kinshasa (/kɪnˈʃɑːsə/; French: [kinʃasa]; Lingala: Kinsásá), formerly named Léopoldville from 1881–1966 (Dutch: Leopoldstad), is the capital and largest city of the Democratic Republic of the Congo. Kinshasa is one of the world's fastest-growing megacities, with an estimated population of 17.8 million in 2024. It is the most densely populated city in the DRC, the third-most populous city and third-largest metropolitan area in Africa, and the world's twenty-second most populous city and fourth-most populous capital city. It is the leading economic, political, and cultural center of the DRC, housing several industries including manufacturing, telecommunications, banking, and entertainment. The city also hosts some of the DRC's significant institutional buildings, such as the People's Palace, Palace of the Nation, Court of Cassation, Constitutional Court, African Union City, Marble Palace, Martyrs Stadium, Government House, Kinshasa Financial Center, and other national departments and agencies.

The Kinshasa site has been inhabited by Teke and Humbu people for centuries and was known as Nshasa before transforming into a commercial hub during the 19th and 20th centuries. The city was named Léopoldville by Henry Morton Stanley in honor of Leopold II of Belgium. The name was changed to Kinshasa in 1966 during Mobutu Sese Seko's Zairianisation campaign as a tribute to Nshasa village. Covering 9,965 square kilometers, Kinshasa stretches along the southern shores of the Pool Malebo on the Congo River. It forms an expansive crescent across flat, low-lying terrain at an average altitude of about 300 meters. Kinshasa borders the Mai-Ndombe Province, Kwilu Province, and Kwango Province to the east; the Congo River delineates its western and northern perimeters, constituting a natural border with the Republic of the Congo; to the south lies the Kongo Central Province. Across the river sits Brazzaville, the smaller capital of the neighboring Republic of the Congo, forming the world's closest pair of capital cities despite being separated by a four-kilometer-wide unbridged span of the Congo River.
