in the second half of the 16th century, king frederick ii of denmark–norway demanded that the tsardom of russia cede the peninsula. russia declined, and in order to organize adequate defenses established the position of a "voyevoda". the "voyevoda" sat in kola, which became the administrative center of the region. prior to that, the administrative duties were performed by the tax collectors from kandalaksha. newly established kolsky uyezd covered most of the territory of the peninsula (with the exception of varzuzhskaya and umbskaya volosts, which were a part of dvinsky uyezd), as well as the northern part of karelia all the way to lendery.
