Chief Njiiri Karanja served as a colonial Chief of the Agîkûyû in Fort Hall (now Murang’a). He narrowly escaped the fate of many of his peers, such as Chiefs Warûhiû and Nderi, who were killed by the Mau Mau, due to his retirement in 1952, just as the Emergency began.
Known as the richest man in Central Kenya during his time, Chief Njiiri’s wealth was substantial and diversified. He possessed a transistor radio, the only one within a 1,000-kilometer radius, symbolizing his immense wealth and foresight. His land holdings were vast, effectively encompassing nearly an entire location in Kinyona, Murang’a County. Additionally, he owned 5,000 goats, 4,000 sheep, and 2,000 cattle.
In an era when owning a bicycle signified status, Chief Njiiri had a Land Rover to transport his grandchildren to school in the 1950s. Despite widespread illiteracy, he ensured his son, Kariuki Njiiri (later an MP for Kigumo), received further education in America. His compound, unlike many of the time, had walls, and entry was strictly controlled by a guard at the gate.
During the freedom struggle, Chief Njiiri was staunchly opposed to the Mau Mau, a stance that necessitated constant protection. He defiantly flew a 60-foot British flag outside his home, signaling his loyalty to the colonial government, which, in turn, provided him with extensive protection. He was guarded by police at the Kinyona station during the day, and a police reserve chopper delivered a copy of the East African Standard to his home daily, which his guard read to him due to his illiteracy. Njiiri School is named in his honor.
