The Konjo and Amba began to agitate for separation from Toro in the 1950s, a movement that became Rwenzururu, an armed secessionist movement, by the mid-1960s. The insurgency ended through a negotiated settlement in 1982, though the Rwenzururu Kingdom was acknowledged by the government in 2008.

 plants when they need it. The nightly frosts affect the sap transport in the plants, and the intake of water by its roots. As the day begins, the air temperature and radiation level rise rapidly, putting strenuous demands on the exposed parts of the plants. It is vital to meet the transpiration demands of the leaves, and maintain a proper water balance. To counter the effects of freezing, the afroalpine plants have developed the insulation systems which give them such a striking appearance. As a rule, these adaptive trends become more prominent as the altitude rises.

Vegetation zones: There are 5 different vegetation zones found in the Rwenzori Mountains. These are grassland (1000–2000m), montane forest (2000–3000m), bamboo/mimulopsis zone (2500–3500m), heather/Rapanea zone (3000–4000m) and the afro-alpine moorland zone (4000–4500m). At higher altitudes some plants reach an unusually large size, such as lobelia and groundsels. The vegetation in the Rwenzori Mountains is unique to equatorial alpine Africa.
