The tradition of Bashkirs to gather for kurultay or iyiyn to discuss the most important issues and solutions to pressing problems is rooted in the deep past. It is documented that Kurultai were still in place in the years 1556-1557, when they deliberated the question of voluntary inclusion of Bashkortostan into Russia. After the agreement on the conditions of entry into Russia, its results have been approved by iyiyn birth.
