The term that best describes the Soviet states' transition into independence is 'challenging'.

Challenging

Explanation:

The Soviet states gained independence after a horrendous conflict with the Tsar. The Tsar had formed a belief amongst the people through the clergies appointed by him.

He was the one chosen by God as a representative of his own to rule over the region. It was difficult to break this belief of the people and transfer the power into the hands of the proletariat .
