Ilūkste county

Ilūkste county (Latvian: Ilūkstes apriņķis, German: Kreis Illuxt, Russian: Иллукстский уезд) was a historic county of the Courland Governorate and of the Republic of Latvia.

Its capital was Ilūkste (Illuxt), but the most populous settlement was Grīva (Griwa-Semgallen) immediately south of Daugavpils (Dünaburg).

After the establishment of the Republic of Latvia in 1918, the Ilūkstes apriņķis[1] existed until 1949, when the Council of Ministers of the Latvian SSR split it into the newly created districts (rajons) of Grīva (dissolved in 1955), Aknīste (dissolved in 1956) and Ilūkste (dissolved in 1962 and merged with the Daugavpils District).

At the time of the Russian Empire Census of 1897, Kreis Illuxt had a population of 66,461.

Of these, 28.5% spoke Latvian, 17.3% Belarusian, 17.1% Polish, 15.2% Russian, 10.5% Lithuanian and 9.6% Yiddish as their native language.
