Võro is a descendant of the old South Estonian regional language and is the least influenced by Standard Estonian (which is based on Northern Estonian dialects).
Võro was once spoken further south and east of historical Võromaa in South Estonian-speaking enclaves Lutsi, Leivu and Kraasna in what is now Latvia and Russia.
In addition to Võro, other contemporary variants of South Estonian include the Mulgi, Tartu and Seto language or dialect.
One of the earliest written evidences of South Estonian is a translation of the New Testament ("Wastne Testament") published in 1686.
Although the status of South Estonian began to diminish after the 1880s, the language began to undergo a revival in the late 1980s. 
The Estonian Police was founded on 12 November 1918, and it existed until the summer of 1940 when the Estonian State formally lost its independence to the Soviet Union.
The foundation of the Estonian Police took place in extremely difficult conditions – at the time of the War of Independence.
The Estonian Police was re-established within the jurisdiction of the Ministry of Internal Affairs in March 1991 by the Police Act.
That was almost half a year before the Estonian State regained its independence.
The act, passed on 20 September 1990, set out the transition period during which the dissolution of the Soviet Militia and the formation of the Estonian Police was to be completed.
The period ended on 1 March 1991 which was the restoration date of the Estonian Police. 
The Estonian Social Democratic Independence Party (, ESDIP) was a social democratic political party in Estonia (then the Estonian SSR), which advocated Estonian independence.

Estonian literature () refers to literature written in the Estonian language (c. 1,100,000 speakers) The domination of Estonia after the Northern Crusades, from the 13th century to 1918 by Germany, Sweden, and Russia resulted in few early written literary works in the Estonian language.

The cultural stratum of Estonian, was originally characterised by a largely lyrical form of folk poetry based on syllabic quantity.
Apart from a few albeit remarkable exceptions, this archaic form has not been much employed in later times.
The most outstanding achievements in this field are the national epic Kalevipoeg (Son of Kalev), written by Friedrich Reinhold Kreutzwald (1803–1882); Gustav Suits's ballad "Lapse sünd" (Birth of a Child); Villem Grünthal-Ridala's (1885–1942) poem "Toomas ja Mai" (Toomas and Mai) and three poems by August Annist (1899–1972).
