evidence: North Kazakhstan Region (Kazakh: Солтүстік Қазақстан облысы, romanized: Soltüstık Qazaqstan oblysy; Russian: Северо-Казахстанская область, romanized: Severo-Kazakhstanskaya oblast) is a region of Kazakhstan, with a population of 539,111. Its capital is Petropavl, with a population of 193,300 people. History [edit]During the 19th century, the territory of the region was home to several Middle Zhuz tribes, including Argyns, Kerei, and Kypshak. During the late 19th and early 20th centuries, the region underwent significant resettlement as a result of the opening of the Siberian railway and the Stolypin agrarian reform. As a result, Ukrainians became the majority population in the northern regions of Kazakhstan and the area was referred to as the "Grey Wedge."[6] [...] - Akkayin District, with the administrative center in the selo of Smirnovo;
