of Lithuania by the 1920 treaty but were not added to Lithuanian SSR include Grodno (Gardinas), Lida (Lyda), Smarhonʹ (Smurgainys), Pastavy (Pastovys), Ashmyany (Ašmena), Braslaw (Breslauja), Suwałki (Suvalkai). Reasons for the territorial changes The redistribution of lands after World War II was based on the ethnicity of local populations – some of the territories that had a clear non-Baltic majority were attached to other republics; this, however, also happened to some territories which had a clear Baltic majority (many of them were enclaves in areas without a Baltic majority). In Latvia and Estonia, parts of territories which had not belonged to the Governorate of Estonia, the Riga Governorate, Vitebsk Governorate or the Courland Governorate within the Russian Empire were detached, but there is no evidence that this was a reason for the transfer of territory. In Lithuania's case, the detaching did not have any historical foundation. History of the territories after resumption of independence Under the Soviet rule the territories that were added to the Russian SFSR and the Byelorussian SSR were largely Russified, due to insufficient support for Lithuanian, Latvian and Estonian languages, characterized by too few schools with curricula in these languages . They saw a significant migration of Russian-speaking people. In some of the territories that became part of Poland, Lithuanian language schools existed and still exist. The territories were not returned to the Baltic states after they regained independence and remain parts of Russia, Belarus and Poland. In general, the official government policy of Latvia and Estonia is not to push the issue, but the territories' return is supported by some, usually marginal, organizations inside these countries, such as the Abreniešu apvienība (Abrenian Union) in Latvia. Estonia The Estonia-Russia border treaty had been signed in Moscow on 18 May 2005 and ratified by Estonia, but was not ratified by Russia — official reason for this was the fact that Estonia's internal treaty ratification legislation passed by parliament mentioned the 1920 Treaty of Tartu (the treaty under which these territories were originally recognised as Estonian). On 6 September 2005, the Russian Ministry of Foreign Affairs summoned Anne Härmaste, Chargé d'Affaires ad interim of Estonia in Russia, and handed her a note containing a notice of the intention of the Russian Federation to withdraw its signature and not to become a party to the Treaty Between the Russian Federation and the Republic of Estonia on the Russian-Estonian State
