Republic of Formosa
The Republic of Formosa survived for only five months. The Japanese landed near Keelung on the northern coast of Taiwan on 29 May 1895, and in a five-month campaign swept southwards to Tainan. During the night of 4 June, on the news that the Japanese had captured Keelung, President T'ang and General Chiu fled to Tamsui, and from there sailed for the mainland on the evening of 6 June. The Japanese entered Taipei shortly afterwards.
Admission to the Union
Some U.S. territories existed only a short time before becoming states, while others remained territories for decades. The shortest-lived was Alabama Territory at 2 years, while New Mexico and Hawaii territories both were in existence for more than 50 years. The entry of several states into the Union has been delayed due to complicating factors. Among them, Michigan Territory, which petitioned Congress for statehood in 1835, was not admitted to the Union until 1837, due to a boundary dispute with the adjoining state of Ohio. The Republic of Texas requested annexation to the United States in 1837, but fears about potential conflict with Mexico delayed the admission of Texas for nine years. Also, statehood for Kansas Territory was held up for several years (1854–61) due to a series of internal violent conflicts involving anti-slavery and pro-slavery factions.
