Reference has already been made to strikes in various parts of the empire. These had been, up to 1918, chiefly due to dissatisfaction over material things--hunger (the strong undercurrent of all dissatisfaction), inadequate clothing, low wages, long hours, etc. They were encouraged and often manipulated by radical Socialists who perceived their importance as a weapon against the government, and were to that extent political, but the first great strike with revolution as its definite aim was staged in Berlin and Essen at the end of January, 1918. The strength of the Independent Socialists and of the more radical adherents of Liebknecht, Ledebour, Rosa Luxemburg and others of the same stamp, while it had increased but slowly in the rural districts and the small towns, had by this time reached great proportions in the capital and generally in the industrial sections of Westphalia. Two great munition plants in Berlin employing nearly a hundred thousand workers were almost solidly Independent Socialist in profession and Bolshevist in fact. The infection had reached the great plants in and around Essen in almost equal degree. A great part of these malcontents was made up of youths who, in their early teens when the war broke out, had for more than three years been released from parental restraint owing to the absence of their soldier-fathers and who had at the same time been earning wages that were a temptation to lead a disordered life. They were fertile ground for the seeds of propaganda whose sowing the authorities were unable to stop, or even materially to check. Even Liebknecht, from his cell, had been able to get revolutionary communications sent out to his followers. The January strike assumed large proportions, and so confident were the Berlin strikers of the strength of their position that they addressed an "ultimatum" to the government. This ultimatum demanded a speedy peace without annexations or indemnities; the participation of workingmen's delegates of all countries in the peace negotiations; reorganization of the food-rationing system; abolishing of the state of siege, and freedom of assembly and of the press; the release of all political prisoners; the democratization of state institutions, and equal suffrage for women. The strikers appointed a workmen's council to direct their campaign, and this council chose an "action commission," of which Haase was a member.
