paragraph: A supporter of Cavaignac and of the parti de l'Ordre, Tocqueville, however, accepted an invitation to enter Odilon Barrot's government as Minister of Foreign Affairs from 3 June to 31 October 1849. There, during the troubled days of June 1849, he pleaded with Jules Dufaure, Interior Minister, for the reestablishment of the state of siege in the capital and approved the arrest of demonstrators. Tocqueville, who since February 1848 had supported laws restricting political freedoms, approved the two laws voted immediately after the June 1849 days, which restricted the liberty of clubs and freedom of the press. This active support in favor of laws restricting political freedoms stands in contrast of his defense of freedoms in Democracy in America. According to Tocqueville, he favored order as "The sine qua non for the conduct of serious politics. He [hoped] to bring the kind of stability to French political life that would permit the steady growth of liberty unimpeded by the regular rumblings of the earthquakes of revolutionary change.'' Tocqueville had supported Cavaignac against Louis Napoleon Bonaparte for the presidential election of 1848. Opposed to Louis Napoleon's 2 December 1851 coup which followed his election, Tocqueville was among the deputies who gathered at the 10th arrondissement of Paris in an attempt to resist the coup and have Napoleon III judged for "high treason", as he had violated the constitutional limit on terms of office. Detained at Vincennes and then released, Tocqueville, who supported the Restoration of the Bourbons against Napoleon III's Second Empire (1851-1871), quit political life and retreated to his castle (Chateau de Tocqueville). Against this image of Tocqueville, biographer Joseph Epstein has concluded: "Tocqueville could never bring himself to serve a man he considered a usurper and despot. He fought as best he could for the political liberty in which he so ardently believed - had given it, in all, thirteen years of his life [....] He would spend the days remaining to him fighting the same fight, but conducting it now from libraries, archives, and his own desk." There, he began the draft of L'Ancien Regime et la Revolution, publishing the first tome in 1856, but leaving the second one unfinished.
