Short answers, pulled from the story.
Benjamin Harrison was the 23rd president of the United States, serving from 1889 to 1893. He was a Republican from Indianapolis, Indiana, a Union Army veteran, and a grandson of the ninth president, William Henry Harrison.
Harrison received 90,000 fewer votes than incumbent Grover Cleveland in the 1888 election but carried the Electoral College 233 to 168. The election turned on swing states, with Harrison winning both New York and Indiana.
The McKinley Tariff, framed by Representative William McKinley and Senator Nelson W. Aldrich and signed by Harrison, enacted the highest average tariff rates in American history. At Secretary of State Blaine's urging, Harrison pushed for reciprocity provisions allowing rate reductions when trading partners lowered their own tariffs, but the tariff remained steep enough that federal spending reached one billion dollars for the first time during his term.
Harrison endorsed the Federal Elections Bill in 1890 and addressed Congress on the 3rd of December 1889, asking when Black Americans would "in fact" have "those full civil rights which have so long been his in law." He also endorsed a constitutional amendment to overturn the Supreme Court's Civil Rights Cases ruling of 1883 and supported federal education funding regardless of students' race. Historians have described these efforts as the last significant attempts to protect civil rights until the 1930s.
Six states were admitted during Harrison's presidency: North Dakota and South Dakota on the 2nd of November 1889; Montana on the 8th of November 1889; Washington on the 11th of November 1889; Idaho on the 3rd of July 1890; and Wyoming on the 10th of July 1890. More states were admitted during his presidency than any other.
Harrison returned to his law practice in Indianapolis, gave lectures at Stanford University in 1894, and published a book on the federal government called This Country of Ours in 1897. In 1898 he represented Venezuela in its boundary dispute with the United Kingdom, filing an 800-page brief and arguing the case in Paris for more than 25 hours. He died of pneumonia in Indianapolis on the 13th of March 1901, at age 67.
