Input: Kievan Rus%27
In the 11th century and the 12th century, the princes and their retinues, which were a mixture of Slavic and Scandinavian elites, dominated the society of Kievan Rus'. Leading soldiers and officials received income and land from the princes in return for their political and military services. Kievan society lacked the class institutions and autonomous towns that were typical of Western European feudalism. Nevertheless, urban merchants, artisans and labourers sometimes exercised political influence through a city assembly, the veche (council), which included all the adult males in the population. In some cases, the veche either made agreements with their rulers or expelled them and invited others to take their place. At the bottom of society was a stratum of slaves. More important was a class of tribute-paying peasants, who owed labour duty to the princes. The widespread personal serfdom characteristic of Western Europe did not exist in Kievan Rus'.

What was the group called that owed labour duty to the princes?
Output: tribute-paying peasants

Input: Dutch language
The term Nederduits, however introduced new confusion, since the non standardised dialects spoken in the north of Germany came to be known as Niederdeutsch as well, and thus the Duits reference in the name was dropped, leading to Nederlands as designation to refer to the Dutch language. The repeated use of Neder (or "low") to refer to the Dutch language is a reference to the Netherlands' downriver location at the Rhine–Meuse–Scheldt delta near the North Sea, harking back to Latin nomenclature, e.g. Germania Inferior. See also: Netherlands (toponymy).

The Netherlands are "low" because of their placement near what delta by the North Sea?
Output: Rhine–Meuse–Scheldt delta

Attestations of Old Dutch sentences are extremely rare. The oldest one first recorded has been found in the Salic law. From this Frankish document written around 510 the oldest sentence has been identified as Dutch: Maltho thi afrio lito (I say to you, I free you, serf) used to free a serf. Another old fragment of Dutch is Visc flot aftar themo uuatare (A fish was swimming in the water). The oldest conserved larger Dutch text is the Utrecht baptismal vow (776-800) starting with Forsachistu diobolae [...] ec forsacho diabolae (Do you forsake the devil? [...] I forsake the devil). Probably the most famous sentence Hebban olla vogala nestas hagunnan, hinase hic enda tu, wat unbidan we nu (All birds have started making nests, except me and you, what are we waiting for), is dated around the year 1100, written by a Flemish monk in a convent in Rochester, England.

Are written records of Old Dutch rare or common?
Output: rare

Input: Galicia (Spain)
The name evolved during the Middle Ages from Gallaecia, sometimes written Galletia, to Gallicia. In the 13th century, with the written emergence of the Galician language, Galiza became the most usual written form of the name of the country, being replaced during the 15th and 16th centuries by the current form, Galicia, which coincides with the Castilian Spanish name. The historical denomination Galiza became popular again during the end of the 19th and the first three-quarters of the 20th century, being still used with some frequency today, although not by the Xunta de Galicia, the local devolved government. The Royal Galician Academy, the institution responsible for regulating the Galician language, whilst recognizing it as a legitimate current denomination, has stated that the only official name of the country is Galicia.

What is one variation of Gallicia's name used during the Middle Ages?
Output:
Galletia
