Input: Read this: Around the sixth century AD, a tribe of Slavs arrived in a portion of Central Europe. According to legend they were led by a hero named Čech, from whom the word "Czech" derives. The ninth century brought the state of Great Moravia, whose first ruler (Rastislav of Moravia) invited Byzantine ruler Michael III to send missionaries in an attempt to reduce the influence of East Francia on religious and political life in his country. These missionaries, Constantine and Methodius, helped to convert the Czechs from traditional Slavic paganism to Christianity and established a church system. They also brought the Glagolitic alphabet to the West Slavs, whose language was previously unwritten. This language, later known as Proto-Czech, was beginning to separate from its fellow West Slavic hatchlings Proto-Slovak, Proto-Polish and Proto-Sorbian. Among other features, Proto-Czech was marked by its ephemeral use of the voiced velar fricative consonant (/ɣ/) and consistent stress on the first syllable.
Question: What kind of system was established by Cech?

Output: unanswerable

Input: Read this: After the formal end of Reconstruction, the struggle over power in Southern society continued. Through violence and intimidation against freedmen and their allies, White Democrats regained political power in Tennessee and other states across the South in the late 1870s and 1880s. Over the next decade, the state legislature passed increasingly restrictive laws to control African Americans. In 1889 the General Assembly passed four laws described as electoral reform, with the cumulative effect of essentially disfranchising most African Americans in rural areas and small towns, as well as many poor Whites. Legislation included implementation of a poll tax, timing of registration, and recording requirements. Tens of thousands of taxpaying citizens were without representation for decades into the 20th century. Disfranchising legislation accompanied Jim Crow laws passed in the late 19th century, which imposed segregation in the state. In 1900, African Americans made up nearly 24% of the state's population, and numbered 480,430 citizens who lived mostly in the central and western parts of the state.
Question: What is the name for laws dating from the late-19th century which promoted segregation?

Output: Jim Crow laws
