Hsinchu Campaign
The Japanese had hoped that their occupation of Taipei on 8 June 1895 would end the fighting in Taiwan. It did not. The Republic of Formosa tottered on for another five months of existence, as its presidency was assumed by Liu Yung-fu on 26 June in Tainan. Liu's assumption of the presidency stiffened the will of ordinary Formosans to resist the invaders. The result was a perceptible growth in guerrilla activity against the Japanese, and as the month of June wore on it became clear that all the island's main towns would have to be occupied forcibly before opposition to the Japanese invasion collapsed. From now on, the capture of Tainan became a political as well as a strategic imperative for the Japanese. During the next four months the Japanese would direct their efforts towards occupying Tainan and snuffing out the nascent Formosan Republic.
Mexican–American War
Mexico obtained independence from Spain and the Spanish Empire with the Treaty of Córdoba in 1821. It briefly experimented with monarchy, but became a republic in 1824. This government was characterized by instability, leaving it ill-prepared for international conflict when war broke out only two decades later, in 1846. In the decades preceding the war, Native American raids in Mexico's sparsely settled north prompted the Mexican government to sponsor migration from the United States to the Mexican province of Texas to create a buffer. However, the newly named "Texians" revolted against the Mexican government of President/dictator Antonio López de Santa Anna, who had usurped the Mexican Constitution of 1824, in the subsequent 1836 Texas Revolution, creating a republic not recognized by Mexico, which still claimed it as part of its national territory. In 1845, the Texan Republic agreed to an offer of annexation by the U.S. Congress and became the 28th state in the Union on December 29 that year.
