Ethnographic Lithuania

Ethnographic Lithuania was an early 20th-century concept that defined Lithuanian territories as a significant part of the territories that belonged to Grand Duchy of Lithuania and Lithuanians as all people living on them, regardless of whether those people spoke Lithuanian language and considered themselves Lithuanian. The concept was in contrast to those of "historic Lithuania" – the territories of the Duchy – and the "linguistic Lithuania", the area where Lithuanian language was overwhelmingly spoken.

The concept of ethnographic Lithuania clashed with the right for self determination of people living in that large territory, particularly Poles and Belarusians, who, according to the supporters of the ethnographic Lithuania, were "slavicized Lithuanians" who needed to be re-Lithuanized. They argued that an individual cannot decide on his ethnicity and nationality, that it is not related to the language but to their ancestry.

In 1920 Lithuanian politician Mykolas Biržiška wrote about nationality: "One cannot define it according to the opinion of every individual. Belonging or not to a given nationality is not something everybody can decide for themselves, it is not something that can be solved according to political liberalism, even if hidden under the cloak of democratic slogans. It is too complex, too tied with ancient history, too related with the history of a given nation, for the will or passivity of any individual to challenge it. [...] Ethnographic Lithuania does not end where the locals no longer speak Lithuanian, it spreads further, to the regions which do not speak - but used to - Lithuanian, since it is composed of one Lithuanian nation, regardless of whether it speaks Lithuanian, has forgotten the language or even holds it in contempt."

The geographical scope of ethnographic Lithuania was noted in 1905, the year of Great Seimas of Vilnius, when Russian prime minister Sergei Witte received the following memorial: "Lithuanians, knowing that territory inhabited by them since the historical times consists of the Lithuanian gubernyas of the Northwestern Krai: Vilna Governorate, Kovno Governorate and Grodno Governorate, part of Courland and Suwałki Governorate (incorporated into the Kingdom of Poland), consider them in the ethnographic perspective Lithuanian, and their inhabitants living there alongside the Lithuanians as either newcomers - such as Poles, Jews and Russians - or slavicized Lithuanians, such as Belarusians."
