Czech literature is the literature written by Czechs, mostly in the Czech language, although other languages like Old Church Slavonic, Latin or German have been also used, especially in the past.
Non-Czech inhabitants of the Czech lands who had written in German and other languages, are usually excluded from the corpus of Czech literature, regardless of their own national self-identification.
Thus Franz Kafka, for example, who wrote in German (though he was also fluent in Czech), is often considered part of Austrian or German literature.
Czech literature is divided into roughly ten main time periods: the Middle Ages; the Hussite period; the years of re-Catholicization and the baroque; the Enlightenment and Czech reawakening in the 19th century; the avantgarde of the interwar period; the years under Communism and the Prague Spring; and the literature of the post-Communist Czech Republic.
Czech literature and culture played a notable role on at least two occasions when Czech society lived under oppression and little to no political activity was possible.
On both of these occasions, in the early 19th century and then again in the 1960s, the Czechs used their cultural and literary effort to create political freedom and to establish a confident, politically aware nation.

Czech literature and culture played a major role on at least two occasions, when Czechs lived under oppression and political activity was suppressed.
On both of these occasions, in the early 19th century and then again in the 1960s, the Czechs used their cultural and literary effort to strive for political freedom, establishing a confident, politically aware nation.
A famous antiwar comedy novel "The Good Soldier Švejk" by Jaroslav Hašek is the most translated Czech book in history.
It was depicted by Karel Steklý in two color films "The Good Soldier Schweik" in 1956 and 1957.
Czech orthography is a system of rules for correct writing (orthography) in the Czech language.
The Czech orthographic system is diacritic.
The háček is added to standard Latin letters for expressing sounds which are foreign to the Latin language (but some digraphs have been kept - "ch, dž").
The acute accent is used for long vowels.
The Czech orthography is considered the model for many other Slavic languages using the Latin alphabet; the Slovenian and Slovak orthographies as well as Gaj's Latin Alphabet are all based on the Czech. 
There are five periods in the development of the Czech orthographic system:Primitive orthography.
For writing sounds which are foreign to the Latin alphabet, letters with similar sounds were used.
The oldest known written notes in Czech originate from the 11th century.
The literature was written predominantly in Latin in this period.
Unfortunately, it was very ambiguous at times, with "c", for example, being used for "c", "č", and "k".
Digraphic orthography.
Various digraphs were used for non-Latin sounds.
The system was not consistent and it also did not distinguish long and short vowels.
It had some features that Polish orthography has kept, such as "cz", "rz" instead of "č", "ř", but was still crippled by ambiguities, such as spelling both "s" and "š" as "s"/"ss", "z" and "ž" as "z", and sometimes even "c" and "č" both as "cz", only distinguishing by context.
Long vowels such as "á" were sometimes (but not always) written double as "aa".
Other features of the day included spelling "j" as "g" and "v" as "w", as the early modern Latin alphabet had not by then distinguished "j" from "i" or "v" from "u".
Diacritic orthography by Jan Hus.
Using diacritics for long vowels ("virgula", an acute, "čárka" in Czech) and "soft" consonants ("punctus rotundus", a dot above a letter, which has survived in Polish "ż") was suggested for the first time in ""De orthographia Bohemica"" around 1406.
Diacritics replaced digraphs almost completely.
It was also suggested that the Prague dialect should become the standard for the Czech language.
Jan Hus is considered to be the author of that work but there is some uncertainty about this.
Brethren orthography.
The Bible of Kralice (1579–1593), the first complete Czech translation of the Bible from the original languages by the Czech Brethren, became the model for the literary form of the language.
The punctus rotundus was replaced by the caron ("háček").
There were some differences from the current orthography, e.g.
the digraph ſſ was used instead of "š"; "ay, ey, au" instead of "aj, ej, ou"; "v" instead of "u" (at the beginning of words); "w" instead of "v"; "g" instead of "j"; and "j" instead of "í" ("gegj" = "její", hers).
"Y" was written always after "c, s" and "z" (e.g.
"cizí", foreign, was written "cyzý") and the conjunction "i" (as well as, and) was written "y".
Modern orthography.
During the period of the Czech National Renaissance (end of the 18th century and the first half of the 19th century), Czech linguists (Josef Dobrovský et al.)
codified some reforms in the orthography.
These principles have been effective up to the present day.
The later reforms in the 20th century mostly referred to introducing loanwords into the Czech language and their adaptation to the Czech orthography.
