Starting in the 1940s, individuals from the various 'Nandi-speaking tribes' who had been drafted to fight in World War II (1939–1945) began using the term Kale or Kore (a term that denoted scarification of a warrior who had killed an enemy in battle) to refer to themselves. At about the same time, a popular local radio broadcaster by the name of John Chemallan would introduce his wartime broadcasts show with the phrase Kalenjok meaning "I tell You" (when said to many people). This would influence a group of fourteen young 'Nandi-speaking' men attending Alliance School and who were trying to find a name for their peer group. They would call it Kalenjin meaning "I tell you" (when said to one person). The word Kalenjin was gaining currency as a term to denote all the 'Nandi-speaking' tribes. This identity would be consolidated with the founding of the Kalenjin Union in Eldoret in 1948 and the publication of a monthly magazine called Kalenjin in the 1950s.
