Input: Read this: At the end of the 15th century the Ottoman Empire advanced all over Southeastern Europe, eventually conquering the Byzantine Empire and extending control over the Balkan states. Hungary was the last bastion of the Latin Christian world in the East, and fought to keep its rule over a period of two centuries. After the tragic death of the young king Vladislaus I of Hungary during the Battle of Varna in 1444 against the Ottomans, the Kingdom was placed in the hands of count John Hunyadi, who became Hungary's regent-governor (1446–1453). Hunyadi was considered one of the most relevant military figures of the 15th century: Pope Pius II awarded him the title of Athleta Christi or Champion of Christ for being the only hope of resisting the Ottomans from advancing to Central and Western Europe.

Input: Read this: Throughout the 14th century, French kings sought to expand their influence at the expense of the territorial holdings of the nobility. They ran into difficulties when attempting to confiscate the holdings of the English kings in southern France, leading to the Hundred Years' War, waged from 1337 to 1453. Early in the war the English under Edward III (r. 1327–77) and his son Edward, the Black Prince (d. 1376),[AF] won the battles of Crécy and Poitiers, captured the city of Calais, and won control of much of France.[AG] The resulting stresses almost caused the disintegration of the French kingdom during the early years of the war. In the early 15th century, France again came close to dissolving, but in the late 1420s the military successes of Joan of Arc (d. 1431) led to the victory of the French and the capture of the last English possessions in southern France in 1453. The price was high, as the population of France at the end of the Wars was likely half what it had been at the start of the conflict. Conversely, the Wars had a positive effect on English national identity, doing much to fuse the various local identities into a national English ideal. The conflict with France also helped create a national culture in England separate from French culture, which had previously been the dominant influence. The dominance of the English longbow began during early stages of the Hundred Years' War, and cannon appeared on the battlefield at Crécy in 1346.
Question: What decade saw the victories of Joan of Arc?

Output:
1420s
