The Abruzzi Expedition of 1906
Almost every peak name you'll encounter on a Rwenzori trek traces back to a single expedition in 1906, led by an Italian prince, which turned this range from a rumoured snow-capped mystery into a properly surveyed mountain system in the space of one season.
Before 1906
By the start of the twentieth century, the Rwenzori's existence as a genuine snow-capped range had been confirmed by Henry Morton Stanley's visits in 1875 and 1888, but the range remained largely unsurveyed — its individual peaks undifferentiated, its highest points unmeasured, and its glaciated summits unclimbed by anyone from outside the region.
The expedition
Luigi Amedeo, Duke of the Abruzzi, brought a full mountaineering expedition to the range in 1906, including experienced Italian alpine guides. Over the course of the expedition, the party properly surveyed the range for the first time from the outside, distinguished the six separate massifs that make up the Rwenzori, reached summits across multiple peaks, and produced the naming framework still in use today — Margherita for the queen of Italy, and a string of other features named for expedition members, sponsors and Italian royalty.
What they actually established
Before 1906, "the Rwenzori" was, from outside the region, essentially one vague snow-capped mass. The Abruzzi expedition's survey work established that it was in fact six distinct massifs, measured their relative heights with a rigor no previous account had attempted, and identified Mount Stanley as the highest, carrying what became known as Margherita Peak.
The published record
Filippo De Filippi, part of the expedition, published the full account afterward — the document that effectively became the foundational reference for Rwenzori mountaineering, cited by essentially every subsequent expedition and, indirectly, by every guidebook and website (including this one) that repeats the range's peak names today.
Why this still matters on the trail
When you stand at a col or hut named after an Italian expedition member or a point of the compass established in 1906, you are standing inside that single season's naming legacy. It's worth knowing, walking past Elena Hut or approaching Margherita Peak, that you are tracing a route effectively laid out — at least in name, if not always in exact line — by one expedition, in one year, more than a century ago.
