dialect was influenced by Polish and developed separately from the Latvian spoken in other parts of Latvia.
In 1772, Latgale was annexed by the Russian Empire, and in 1865, as part of Russia's anti-Polish policies, a period of Russification was begun, during which the Latgalian language (written in Latin script) was forbidden. This ban was lifted in 1904, and a period of Latgalian reawakening began. Many Latgalian public figures sought reunification with the rest of Latvia at the Congress of R?zekne in 1917, while some preferred autonomy or incorporation in Russia. The decisions of the 1917 Congress and the declaration of independence on 18 November 1918, claiming Latgale as part of the Latvian state, moved both Latvian armed forces as well as local partisans to fight for the liberation of Latgale: a difficult task, given the territorial interests of both Bolshevik Russia and Poland.
In 1920 Latgale was incorporated into Latvia. By the peace treaty of 1920 with Soviet Russia, parts of the Vitebsk Governorate and Pskov Governorate were incorporated into the new Republic of Latvia. United with other ethnic Latvian territories, as claimed by the declaration of independence (ethnic borders as national borders), they formed the districts of Daugavpils, Ludza, R?zekne and Jaunlatgale, later Abrene district.
In 1944, at the beginning of the second occupation of Latvia by the USSR, the eastern municipalities of the Abrene district were incorporated into the Russian Federation
