Millard Fillmore is considered one of the least successful Presidents. But his administration had two important accomplishments: the Compromise of 1850 and the opening of Japan.
Born in a poor family, Fillmore became a lawyer in Buffalo, New York, and a congressman. In 1848, he was elected Vice President, and the death of President Zachary Taylor in July, 1850, made him President.
At that time, Congress was debating the Compromise of 1850, a group of laws designed to calm the disputes over slavery. Fillmore disliked slavery but wanted to preserve the Union. So he supported the Compromise, which admitted California as a free state and ended slavery in the District of Columbia and made it easier for southerners to recover runaway slaves. The Compromise helped delay the Civil War for 10 years
With California now a state, the U.S. looked to the Pacific. In 1852, Fillmore sent a fleet under Commodore Matthew C. Perry to Japan, which had been closed to foreigners for 200 years.
This show of force resulted in a treaty opening two Japanese ports to U.S. trade. But when the treaty was signed in 1854. Fillmore was no longer President. Unpopular for his support of the Compromise of 1850, he was denied the 1852 presidential nomination.
IN 1856, Fillmore ran for President for the anti-immigrant Americans, or Know-Nothing Party. Maryland was the only state he carried.
