[8][9] Guek Ngundeng was believed to have been born in 1890 in Wech Deng village, Nyirol County of Lou Nuer territory today part of Jonglei State, South Sudan.
[10][6] The colonial administration carried out a military campaign against Guek and the other two Lou prophets Puok Kerjiok and Char Koryom in 1917.
Guek was cleared of the charges of rebellion, but he followed his father's reluctance to deal directly with government officials.
following the Royal Air Force raid, the government in Khartoum announced to the world that the Ngundeng Pyramid was "destroyed completely".
By January 1929 another government troops were sent to Wech Deng and encountered Guek leading large numbers of spear-carrying Nuer warriors dancing at the base of the Pyramid.
Guek’s dead body, drum(bul), rod(dang), and brass pipe(tony) were found beside the slain white bull.
