The Mountains of the Moon

History of the Rwenzoris

“A story of ancient geographical mystery, exploration, scientific discovery, mountaineering, and conservation.”

The Rwenzori Mountains are one of Africa’s most remarkable mountain ranges. They lie along the border between western Uganda and the Democratic Republic of the Congo (DRC), close to the Equator. The range is famous for its snow- and glacier-covered peaks, deep valleys, lakes, waterfalls and distinctive high-altitude vegetation. Its highest point, Margherita Peak on Mount Stanley, rises to 5,109 metres above sea level, making it the third-highest mountain peak in Africa.

The history of the Rwenzori Mountains can be studied through several important periods: the ancient descriptions of the Mountains of the Moon, the long period when European explorers attempted to locate the mountains, the first reliable European observations in the nineteenth century, the major expeditions of the late nineteenth and early twentieth centuries, and the development of the mountains as a protected natural and historical heritage site.

1. Ancient History & Origins

Long before European explorers reached the Rwenzori, knowledge of great mountains associated with the source of the Nile existed in ancient geographical writings. The Greek-Egyptian geographer Claudius Ptolemy, writing in the second century CE, described a mountain range called the Lunae Montes, or Mountains of the Moon, in connection with the sources of the Nile.

The name Rwenzori has a long and interesting history. Henry Morton Stanley recorded the name in the nineteenth century in forms such as “Ruwenzori.” The name is associated with the languages of the people who have traditionally lived around the mountains. Some historical sources explain it as referring to rain, clouds or a rain-producing mountain region. The mountains are frequently covered by clouds and receive substantial rainfall, making such an interpretation particularly appropriate.

For centuries, geographers tried to determine the actual location of these legendary mountains. Water from the mountains contributes to the Nile system, and the range is recognized as one of the important highland water sources of the Nile basin.

3. Early European Attempts

During the nineteenth century, European explorers became increasingly interested in discovering the source of the Nile. Explorers like Samuel Baker and Romolo Gessi reported seeing mountains or highlands in the distance around Lake Albert. However, clouds, mist, and difficult terrain made it difficult to determine the exact nature and location of the snow-covered mountains, keeping them one of the great geographical mysteries of nineteenth-century Africa.

4. Henry Morton Stanley

A major turning point came on 24 May 1888, when the British-American explorer Henry Morton Stanley observed the snow-covered Rwenzori Mountains. His observations provided important confirmation that a substantial snow-capped mountain range existed in equatorial Africa. Stanley associated the mountains with the ancient Mountains of the Moon, connecting the legendary descriptions with a real mountain range.

5. Scientific Surveys & Early Exploration

After Stanley’s observations, scientific interest increased. In 1891, the German explorer and scientist Franz Stuhlmann led an expedition, moving exploration beyond observation toward systematic geographical and scientific investigation. He studied the vegetation and physical characteristics, making early attempts to survey the peaks.

During the 1890s and early 1900s, figures like G. F. Scott Elliot investigated the mountain forests and high-altitude areas. Although explorers penetrated deeply into the mountains before 1906, the highest glaciated peaks remained extremely difficult to reach. Consequently, the Rwenzori was still largely unexplored at the beginning of the twentieth century.

7. The Duke of Abruzzi Expedition (1906)

The most important expedition in the early exploration history was led by Luigi Amedeo, Duke of Abruzzi, an Italian explorer and mountaineer. The expedition included experienced climbers, scientists, and the famous Italian photographer Vittorio Sella.

In June 1906, members successfully reached the highest summit of the range, Margherita Peak on Mount Stanley, at approximately 5,109 metres. The 1906 expedition was a landmark because it transformed knowledge of the Rwenzori from a mysterious range into a surveyed scientific region.

8. Naming the Major Peaks

During the Duke of Abruzzi’s expedition, several peaks received names associated with members of the Italian royal family and other figures. Mount Stanley contains Margherita Peak, named in honour of Queen Margherita of Italy. Other major groups include Mount Speke, Mount Baker, Mount Emin, Mount Gessi, and Mount Luigi di Savoia.

10. Scientific and Geographical Importance

Exploration revealed that the mountains were scientifically unusual. Unlike Mount Kilimanjaro and Mount Kenya, which are volcanic mountains, the Rwenzori are a non-volcanic mountain range formed through geological uplift. The range contains ancient crystalline rocks, including gneiss and quartzite.

The mountains developed distinctive glaciers, lakes, and valleys. Their geological and climatic history makes them important for studying mountain formation, glaciation, and environmental change. The Rwenzori’s glaciers are especially significant because they exist close to the Equator.

11. Conservation & UNESCO World Heritage

As scientific knowledge increased, concern grew about protecting its forests, wildlife, glaciers, water catchments, and unique high-altitude ecosystems. In 1991, the Rwenzori Mountains National Park was established in Uganda to protect its exceptional natural resources. The mountains became an internationally important conservation area.

In 1994, Rwenzori Mountains National Park was inscribed on the UNESCO World Heritage List because of its outstanding natural beauty and exceptional biodiversity. UNESCO describes the park as an important water catchment and notes its unusual alpine vegetation, including giant heathers, lobelias, and groundsels.

Today, the Rwenzori Mountains are important for scientific research, conservation, tourism and mountaineering. Scientists continue to study the glaciers, vegetation, wildlife, geology and effects of climate change.

2nd Century CE

Claudius Ptolemy described the legendary Lunae Montes, or Mountains of the Moon, associated with the Nile’s source.

1860s

Explorers including Samuel Baker contributed to European knowledge of the mountainous region around the Nile and Lake Albert.

1888

The history of the Rwenzori Mountains is a story of ancient geographical mystery, exploration, scientific discovery, mountaineering and conservation.

Today, the Rwenzori Mountains remain historically important not only because of their association with the Mountains of the Moon and the history of African exploration, but also because they are an exceptional natural landscape, a major water catchment and an important centre for scientific research and conservation.
