Around 1620 the emperor imported a wallonian-French winefarmer Duvont, who later invented the later known "king of wines"-methode in the Tokaji-district. In honour of Mr. Duvonts exceptional skills, the emperor ennobled this farmer, and gave him one of his many villages (Kiralyfalva) now Königsdorf in Austria. The emperor then named the family Királyfalvy. Tokaji wine became an increasingly important commodity for the region from the 17th century, its export being a major source of income for the ruling princes of Transylvania to which the Tokaj region belonged at the time. Indeed, revenues from the increasingly renowned Tokaji Aszú wine helped to pay for the wars of independence fought against Austrian Habsburg rule. The repute of Tokaji wine was enhanced when in 1703, Francis II Rákóczi, prince of Transylvania, gave King Louis XIV of France a gift of numerous bottles of wine from his Tokaj estate. Tokaji wine was then served at the Versailles Court, where it became known under the name of Tokay. Delighted with the precious beverage, Louis XIV declared it "Vinum Regum, Rex Vinorum" ("Wine of Kings, King of Wines"). In the 18th Century, Tokaj reached the height of its prosperity. Both Poland and Russia had become major export markets for its wine. Such was the importance of Tokaji in Russia, that the Russian emperors maintained a de facto colony in Tokaj in order to guarantee the supply of wine to the Imperial Court. The partition of Poland in 1795 and subsequent imposition of customs duties dealt a severe blow to the exports of Tokaji wine and precipitated the economic decline of the region. However, this was only the first of three major crises for Tokaj. The second occurred when the phylloxera epidemic reached Tokaj in 1885 and destroyed the vast majority of the vineyards in a matter of years. Division of Tokaj-Hegyalja Following the signature of the peace Treaty of Trianon in June 1920, Hungary lost two-thirds of its territory, and the Tokaj wine region was divided between Hungary and the newly created Czechoslovakia. A state border has been set on the Ronyva creek and small suburb of Hungarian town Sátoraljaújhely (Kiskarlapuszta, Nagykarlapuszta, Állomás) was granted to Czechoslovakia (today Slovakia) and became a village called Slovenské Nové Mesto (English: Slovak New Town), (Hungarian: Újhely). Out of the historical Tokaj-Hegyalja wine region, Czechoslovakia gained an area of 175 hectares of vineyards and 3 villages: Malá Tŕňa (Hungarian: Kistoronya),
