After four years on the sidelines, Austria sought another war with France to avenge its recent defeats. Austria could not count on Russian support because the latter was at war with Britain, Sweden, and the Ottoman Empire in 1809. Frederick William of Prussia initially promised to help the Austrians, but reneged before conflict began. A report from the Austrian finance minister suggested that the treasury would run out of money by the middle of 1809 if the large army that the Austrians had formed since the Third Coalition remained mobilized. Although Archduke Charles warned that the Austrians were not ready for another showdown with Napoleon, a stance that landed him in the so-called "peace party," he did not want to see the army demobilized either. On 8 February 1809, the advocates for war finally succeeded when the Imperial Government secretly decided on another confrontation against the French.
On what date did the Austrian government secretly decide on going to war with France?
8 February 1809

Greenhouses convert solar light to heat, enabling year-round production and the growth (in enclosed environments) of specialty crops and other plants not naturally suited to the local climate. Primitive greenhouses were first used during Roman times to produce cucumbers year-round for the Roman emperor Tiberius. The first modern greenhouses were built in Europe in the 16th century to keep exotic plants brought back from explorations abroad. Greenhouses remain an important part of horticulture today, and plastic transparent materials have also been used to similar effect in polytunnels and row covers.
What was one of the first uses of a greenhouse?
produce cucumbers year-round for the Roman emperor Tiberius

Laws were instituted that required every able-bodied male Japanese citizen, regardless of class, to serve a mandatory term of three years with the first reserves and two additional years with the second reserves. This action, the deathblow for the samurai warriors and their daimyo feudal lords, initially met resistance from both the peasant and warrior alike. The peasant class interpreted the term for military service, ketsu-eki (blood tax) literally, and attempted to avoid service by any means necessary. The Japanese government began modelling their ground forces after the French military. The French government contributed greatly to the training of Japanese officers. Many were employed at the military academy in Kyoto, and many more still were feverishly translating French field manuals for use in the Japanese ranks.
Laws mandated that every able bodies Japanese citizen do what?
serve a mandatory term of three years with the first reserves and two additional years with the second reserves.
