Kostanay land is the birthplace of many great sons of the Kazakh people. Mighty batyrs and wise biys lived here, orators with apt poetic words who solved the most complex inter-tribal conflicts in their time. The talented military commander, brave batyr, hero of battles with juggars Shakshak Zhanibek Koshkaruly was the first among the noble Kazakhs to receive the honorary title of tarkhan. Barak-batyr Karabaluanuly became famous for his participation in the peasant war led by Yemelyan Pugachev, and then in the national liberation movement led by Syry Datov. The descendants of Zhabaga batyr keep the battle banner of their brave ancestor as a relic.

The name of Tatikara is inscribed in golden letters in the anthology of Kazakh literature. He was the standard-bearer of Abylai Khan and the most beloved zhyrau of the people.
