Police and fiscal supervision by the United States has characterized the recent history of Panama. Not only has a proposed increase in the customs duties been disallowed, but more than once the unrest attending presidential elections has required the calming presence of American officials. As a means of forestalling outbreaks, particularly in view of the cosmopolitan population resident on the Isthmus, the republic enacted a law in 1914 which forbade foreigners to mix in local politics and authorized the expulsion of naturalized citizens who attacked the Government through the press or otherwise. With the approval of the United States, Panama entered into an agreement with American financiers providing for the creation of a national bank, one-fourth of the directors of which should be named by the Government of the republic. The second period of American rule in Cuba lasted till 1909. Control of the Government was then formally transferred to Jose Miguel Gomez, the President who had been chosen by the Liberals at the elections held in the previous year; but the United States did not cease to watch over its chief Caribbean ward. A bitter controversy soon developed in the Cuban Congress over measures to forbid the further purchase of land by aliens, and to insure that a certain percentage of the public offices should be held by colored citizens. Though both projects were defeated, they revealed a strong antiforeign sentiment and much dissatisfaction on the part of the negro population. It was clear also that Gomez, intended to oust all conservatives from office, for an obedient Congress passed a bill suspending the civil service rules. The partisanship of Gomez, and his supporters, together with the constant interference of military veterans in political affairs, provoked numerous outbreaks, which led the United States, in 1912, to warn Cuba that it might again be compelled to intervene. Eventually, when a negro insurrection in the eastern part of the island menaced the safety of foreigners, American marines were landed. Another instance of intervention was the objection by the United States to an employers' liability law that would have given a monopoly of the insurance business to a Cuban company to the detriment of American firms. After the election of Mario Menocal, the Conservative candidate, to the presidency in 1912, another occasion for intervention presented itself. An amnesty bill, originally drafted for the purpose of freeing the colored insurgents and other offenders, was amended so as to empower the retiring President to grant pardon before trial to persons whom his successor wished to prosecute for wholesale corruption in financial transactions. Before the bill passed, however, notice was sent from Washington that, since the American Government had the authority to supervise the finances of the republic, Gomez would better veto the bill, and this he accordingly did.
