What former president of Mexico declared himself president again and unsuccessfully tried to fight off the U. S.?

Explanation:

The United States involvement in the Mexican Revolution was varied and seemingly contradictory, first supporting and then repudiating Mexican regimes during the period 1910–1920.[1] For both economic and political reasons, the U.S. government generally supported those who occupied the seats of power, but could withhold official recognition. The U.S. supported the regime of Porfirio Díaz (1876–1880; 1884–1911) after initially withholding recognition since he came to power by coup. In 1909, Díaz and U.S. President Taft met in Ciudad Juárez, across the border from El Paso, Texas. Prior to Woodrow Wilson's inauguration on March 4, 1913, the U.S. Government focused on just warning the Mexican military that decisive action from the U.S. military would take place if lives and property of U.S. nationals living in the country were endangered.[2] President William Howard Taft sent more troops to the US-Mexico border but did not allow them to intervene directly in the conflict,[3][4] a move which Congress opposed.[4] Twice during the Revolution, the U.S. sent troops into Mexico, to occupy Veracruz in 1914 and to northern Mexico in 1916 in a failed attempt to capture Pancho Villa. Although U.S. foreign policy toward Latin America was to assume the region was the sphere of influence of the U.S., articulated in the Monroe Doctrine and in Theodore Roosevelt's corollary to the Monroe Doctrine, which asserted the right of the U.S. to intervene militarily in the region to restore order if in the U.S. view a nation could not or would not do it itself, the U.S. role in the Mexican Revolution has been exaggerated. It did not directly intervene in the Mexican Revolution in a sustained manner.[5]

Explanation:

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
