On 13 December [O.S. 30 November] 1904, the Moscow City Duma passed a resolution demanding establishment of an elected national legislature, full freedom of the press, and freedom of religion. Similar resolutions and appeals from other city dumas and zemstvo councils followed.
On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted a Hungarian patent (No. 34541) for a tungsten filament lamp that lasted longer and gave brighter light than the carbon filament. Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. This type is often called Tungsram-bulbs in many European countries. Filling a bulb with an inert gas such as argon or nitrogen slows down the evaporation of the tungsten filament compared to operating it in a vacuum. This allows for greater temperatures and therefore greater efficacy with less reduction in filament life.
Tsar Nicholas II made a move to fulfil many of these demands, appointing liberal Pyotr Dmitrievich Sviatopolk-Mirsky Minister of the Interior after the assassination of Vyacheslav von Plehve. On 25 December [O.S. 12 December] 1904, the Tsar issued a manifesto promising the broadening of the Zemstvo and more authority local municipal councils, insurance for industrial workers, the emancipation of Inorodtsy and the abolition of censorship. The crucial demand of representative national legislature was missing in the manifesto.
