Latgalian language
Originally Latgalians were a tribe living in modern Vidzeme and Latgale. It is thought that they spoke the Latvian language, which later spread through the rest of modern Latvia, absorbing features of the Old Curonian, Semigallian, Selonian and Livonian languages. The Latgale area became politically separated during the Polish–Swedish wars, remaining part of the Polish–Lithuanian Commonwealth as the Inflanty Voivodeship, while the rest of Latvians lived in lands dominated by Baltic German nobility. Both centuries of separate development and the influence of different prestige languages likely contributed to the development of modern Latgalian as distinct from the language spoken in Vidzeme and other parts of Latvia.

After that other deputies, local government representatives and public officials from Harmony Centre began to sign it as well, including MP Nikolai Kabanov who was later issued a written warning by the The Saeima Mandate, Ethics and Submissions Committee for violating the deputy's solemn vow (oath), in which Kabanov swore to strengthen the Latvian language as the only official language. Harmony MP Andrejs Klementjevs had refused to formulate his party association's official position, stating that Harmony Centre has distanced itself from the matter, however they will examine the proposal carefully should it reach the parliament.
