On 19 September 1905, the typesetters at the Ivan Sytin's printing house in Moscow went out on strike for shorter hours and higher pay. By the evening of 24 September, the workers at 50 other printing shops in Moscow were also on strike. On 2 October 1905, the typesetters in printing shops in Saint Petersburg decided to strike in support of the Moscow strikers. On 7 October 1905, the railway workers of the Moscow–Kazan Railway went out on strike. Amid the resulting confusion, Trotsky returned from Finland to Saint Petersburg on 15 October 1905. On that day, Trotsky spoke before the Saint Petersburg Soviet Council of Workers Deputies, which was meeting at the Technological Institute in the city. Also attending were some 200,000 people crowded outside to hear the speeches—about half of all workers in Saint Petersburg.
