question:
Question: What year was the treaty that opened up the Korean Peninsula to Japanese trade signed? Passage:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.

question:
Question: What party controlled the legislative branch of government the  Dixiecrats hoped to force a contingent election in 1948? Passage:Truman had acceded to the presidency in April 1945 after the death of Franklin D. Roosevelt. Defeating attempts to drop him from the ticket, Truman won the presidential nomination at the 1948 Democratic National Convention. The Democratic convention's civil rights plank caused a walk-out by several Southern delegates, who launched a third-party "Dixiecrat" ticket led by Governor Strom Thurmond of South Carolina. The Dixiecrats hoped to win enough electoral votes to force a contingent election in the House of Representatives, where they could extract concessions from either Dewey or Truman in exchange for their support. Truman also faced a challenge from the left in the form of former Vice President Henry A. Wallace, who launched the Progressive Party and challenged Truman's confrontational Cold War policies. Dewey, who was the leader of his party's moderate eastern wing and had been the 1944 Republican presidential nominee, defeated Senator Robert A. Taft and other challengers at the 1948 Republican National Convention.

question:
Question: How old was Mitchel when the event where he served with the Union began? Passage:John Mitchel, the most committed advocate of revolution, had been arrested early in 1848, then convicted on the purposefully–created charge of Treason-felony. He was sentenced to transportation to Bermuda, where he joined other convicts labouring on the construction of the Royal Naval Dockyard on Ireland Island. He was subsequently sent to Van Diemen's Land (in present-day Tasmania, Australia) where he was soon to be joined by other leaders, such as William Smith O'Brien and Thomas Francis Meagher who had both been arrested after Ballingarry. John Blake Dillon escaped to France, as did three of the younger members, James Stephens, John O'Mahony and Michael Doheny. Meagher and John Mitchel (who had been transported there before for political activities) both managed to escape and emigrate to the United States in the early 1850s. They served on opposite sides of the American Civil War: Meagher serving with the Union, for which he recruited and commanded the Irish Brigade, and Mitchel allying himself with the South and living there, sending three sons to fight with the Confederacy.
