Latgalian language
Latgalian is spoken in Latgale, the eastern part of Latvia. It is debated whether it is a separate language or a distinct dialect of Latvian. Nevertheless, its standardized form is recognized and protected as a "historical variety of the Latvian language" "(vēsturisks latviešu valodas paveids)" by Latvian law. The 2011 Latvian census established that 8.8% of Latvia's inhabitants, or 164,500 people, speak Latgalian daily. 97,600 of them live in Latgale, 29,400 in Riga and 14,400 in the Riga region.
Livonia
The historical land of Livonia has been split between Latvia and Estonia ever since. The Livonian language is spoken by fewer than 100 individuals as a second language, and is understood to be fast approaching extinction. The last native Livonian speaker died in June 2013.
The anthem (unofficial) of Livonians is "Min izāmō, min sindimō" sharing the melody of Finnish and Estonian anthems.
