In the history of United States foreign policy, the Roosevelt Corollary was an addition to the Monroe Doctrine articulated by President Theodore Roosevelt in his 1904 State of the Union Address, largely as a consequence of the Venezuelan crisis of 1902–1903. The corollary states that the United States could intervene in the internal affairs of Latin American countries if they committed flagrant wrongdoings that "loosened the ties of civilized society".
Herbert Hoover's tenure as the 31st president of the United States began on his inauguration on March 4, 1929, and ended on March 4, 1933.

His presidency ended following his landslide defeat in the 1932 presidential election by Democrat Franklin D. Roosevelt, after one term in office.
Fifteen presidents of the United States have made thirty-four presidential visits to Mexico. The first visit by an incumbent president to Mexico was made in 1909 by William Howard Taft. It was only the second time in U.S. history that a president left the country while in office.
Seven United States presidents have made presidential visits to Sub-Saharan Africa. The first was an offshoot of Franklin D.

Ten United States presidents have made presidential visits to Eastern Europe and Northern Asia. The first trip by an incumbent president to Eastern Europe was made by Franklin D. Roosevelt in 1945, to the Soviet Union, and was an offshoot of Allied diplomatic interactions during World War II. The first trip by an incumbent president to Northern Asia was made by Gerald Ford in 1974, also to the Soviet Union, and was an offshoot of U.S.–Soviet Détente during the Cold War. The first presidential visits to other Eastern European countries occurred during this era of easing geo-political tensions as well.
Nine presidents of the United States have made presidential visits to North Africa. The first trips by a sitting president to countries in North Africa were those of Franklin D. Roosevelt, and were an offshoot of Allied diplomatic interactions during World War II. Of the five countries in the region, only Libya has not yet been visited by an American president.
Ten United States presidents have made presidential visits to the Middle East. The first trips by an incumbent president to countries in the Middle East were those by Franklin D. Roosevelt, and were an offshoot of Allied diplomatic interactions during World War II. To date, 16 visits have been made to Egypt, 12 to Saudi Arabia, 11 to Israel, six to both Iraq, Jordan and Turkey, four to Iran, three to the Palestinian Territories, two to both Kuwait and Syria, one to Bahrain, Georgia, Oman, Qatar, and to the United Arab Emirates. No incumbent American president has yet visited Armenia, Azerbaijan, Cyprus, Lebanon, and Yemen.
Eleven United States presidents and one president-elect have made presidential visits to South America. The first trip was made by Herbert Hoover in 1928. During this tour he delivered twenty-five speeches in ten Central and South American countries, almost all of which stressed his plans to reduce American political and military interference in Latin American affairs. In sum, he pledged that the United States would act as a "good neighbor."
Nine United States presidents and one president-elect have made presidential visits to the Caribbean since 1928. Franklin D. Roosevelt made the most trips to the Caribbean islands (14), either for vacation or while involved with Allied diplomatic interactions during World War II. Of the 13 sovereign countries in the region, four—Dominica, the Dominican Republic, Saint Kitts and Nevis, and Saint Vincent and the Grenadines—have not as of yet been visited by an American president.
Thirteen United States presidents have made presidential visits to Southern Europe. Woodrow Wilson became the first incumbent president to visit a Southern European country in January 1919 in the aftermath of World War I. Visits occurring during the 1940s through 1980s were offshoots of American diplomatic interactions during World War II and then the Cold War.
The presidential transition of Herbert Hoover began when he won the United States 1928 United States presidential election, becoming the president-elect, and ended when Hoover was inaugurated on March 4, 1929.
