 "Peter Kondratyevitch Pavlenko" was principal of the Halbstadt Zentralschule in 1909 and 1910, also teaching in the areas of mathematics and pedagogy; before that he had been on the faculty of the secondary school in Orikhiv.In 1918-1919 Orikhiv was in the centre of the area controlled by the anarchist Nestor Makhno, so it likely suffered the usual consequences of being occupied by his army.During the subsequent Civil War it was overrun a number of times as the vicissitudes of war caused frequent changes in the struggles between the Whites and the Reds.
