According to most chronicles, Dragoș arrived in Moldavia in 1359. The "Moldo-Polish Chronicle" is the sole exception, which states that Dragoș's "dismounting" occurred in 1352. Historians still debate the year of the foundation of Moldavia. Many historians (including Ștefan S. Gorovei, Dennis Deletant, Neagu Djuvara, and Constantine Rezachevici) propose an early date, 1347 or even 1345. They say that a successful Hungarian campaign under the command of Andrew Lackfi, Count of the Székelys, against the Tatars across the Carpathians in 1345 gave rise to the development of a defensive march, ruled by Dragoș. According to Deletant, the establishment of that border province was connected to the foundation of the Roman Catholic Diocese of Milkovia, which was sanctioned, upon the request of Louis I of Hungary, by Pope Clement VI on 27 March 1347.
