When the February revolution of 1848 broke out, Marx was in Brussels. The authorities there compelling him to leave Belgian soil, at the request of the Prussian government, he returned to Paris, but not for a long stay. The revolutionary struggle in Germany stirred his blood, and with Engels, Wilhelm Wolf, the intimate friend to whom he later dedicated the first volume of "Capital," and Ferdinand Freiligrath, the fiery poet of the movement, Marx started the _New Rhenish Gazette_. Unlike the first _Rhenish Gazette_, the new journal was absolutely free from control by business policy. Twice Marx was summoned to appear at the Cologne assizes, upon charges of inciting the people to rebellion, and each time he defended himself with superb audacity and skill, and was acquitted. But in June, 1849, the authorities suppressed the paper, because of the support it gave to the risings in Dresden and the Rhine Province. Marx was expelled from Prussia and once more sought a refuge in Paris, which he was allowed to enjoy only for a very brief time. Forbidden by the French government to stay in Paris, or any other part of France except Brittany, which, says Liebknecht, was considered "fireproof," Marx turned to London, the mecca of all political exiles, arriving there toward the end of June, 1849. His removal to London was one of the crucial events in the life of Marx. It became possible for him, in the classic land of capitalism, to pursue his economic studies in a way that was not possible anywhere else in the world. As Liebknecht says: "Here in London, the metropolis (mother city) and the center of the world, and of the world of trade--the watch tower of the world whence the trade of the world and the political and economical bustle of the world may be observed, in a way impossible in any other part of the globe--here Marx found what he sought and needed, the bricks and mortar for his work. 'Capital' could be created in London only."[149]
