No it's not only for wars...
Famine of 1866–68
The government of the Grand Duchy of Finland was ill-equipped to handle a crisis of such magnitude. There was no money readily available to import food from largely monopolized Central European markets, and the government was slow to recognize the severity of the situation. Finance minister Johan Vilhelm Snellman, in particular, did not want to borrow, lest Finland's recently introduced currency, the Finnish markka, be weakened because of the very high interest rates that the Rothschild bank of Frankfurt asked for. In Finland the Rothschild interest rates were seen as usury. When money was finally borrowed from the Rothschild bank of Frankfurt in late 1867, the crisis was already full blown, and grain prices had risen in Europe. In addition, it was difficult to transport what little aid could be mustered in a country with poor communications. A number of emergency public works projects were set up, foremost among them the construction of the railway line from Riihimäki to Saint Petersburg.
