The actions of March 2014 and the annexation of Crimea to Russia created a special situation for the Baltic states. In the case of Estonian society, it is significant that the smallest of the Baltic states consists of 25% of the Russian minority. The large Russian minority is undoubtedly a factor that increases the threat from Russia. It also creates integration problems caused by ethnic divisions. The article analyzes the situation of the Russian minority in Estonia, highlighting the problematic areas that may be the cause of Russian intervention in this region. The Estonian government has started and is consistently introducing several integration programs, the main goal of which is to create a coherent and as homogeneous society as possible. Although there is an increase in the use of the Estonian language by national minorities, there are still serious linguistic deficiencies that prevent effective communication in Estonian. Such a situation limits the chances on the labor market and lowers the social status. In the midst of many antagonisms and social inequalities, both Estonians and Russians must build a coexistence in an independent Estonia. On the other hand, Russia's goal is to protect all Russian minorities living abroad, and this seems to be a potential security threat, in this case, Estonia.
