Input: Ottoman Empire
Part of the Ottoman territories in the Balkans (such as Thessaloniki, Macedonia and Kosovo) were temporarily lost after 1402 but were later recovered by Murad II between the 1430s and 1450s. On 10 November 1444, Murad II defeated the Hungarian, Polish, and Wallachian armies under Wadysaw III of Poland (also King of Hungary) and John Hunyadi at the Battle of Varna, the final battle of the Crusade of Varna, although Albanians under Skanderbeg continued to resist. Four years later, John Hunyadi prepared another army (of Hungarian and Wallachian forces) to attack the Turks but was again defeated by Murad II at the Second Battle of Kosovo in 1448.

Who recovered Ottoman empire territories in the Balkans in the 1430s to the 1450s?

Input: Switzerland
The structure of the Swiss militia system stipulates that the soldiers keep their Army issued equipment, including all personal weapons, at home. Some organizations and political parties find this practice controversial but mainstream Swiss opinion is in favour of the system. Compulsory military service concerns all male Swiss citizens; women can serve voluntarily. Men usually receive military conscription orders for training at the age of 18. About two thirds of the young Swiss are found suited for service; for those found unsuited, various forms of alternative service exist. Annually, approximately 20,000 persons are trained in recruit centres for a duration from 18 to 21 weeks. The reform "Army XXI" was adopted by popular vote in 2003, it replaced the previous model "Army 95", reducing the effectives from 400,000 to about 200,000. Of those, 120,000 are active in periodic Army training and 80,000 are non-training reserves.

Who has compulsory military service in Switzerland?
Output: all male Swiss citizens

Input: Late Middle Ages
Though there is no doubt that the demographic crisis of the 14th century caused a dramatic fall in production and commerce in absolute terms, there has been a vigorous historical debate over whether the decline was greater than the fall in population. While the older orthodoxy held that the artistic output of the Renaissance was a result of greater opulence, more recent studies have suggested that there might have been a so-called 'depression of the Renaissance'. In spite of convincing arguments for the case, the statistical evidence is simply too incomplete for a definite conclusion to be made.

What is the alternative to the theory that the Renaissance was a time of great opulence?
Output:
depression of the Renaissance
