Until the 1990s, both governments claimed to be the legitimate government
for China as a whole. The ROC eventually dropped the claim. How did this
change in ROC policy most likely change relations between the two
governments?

The sovereign legitimacy demanded by the government of the Republic of China, in the name of the continuity of a regime founded in 1911 and heir to the rule of Chang Kai Shek defeated by Mao Zedong and confined to the island since 1949, results in the paradoxical situation of Taipei aligning alongside Beijing in disputes in which Washington, which cultivates neutrality in these border disputes, is the military guarantor of regional security vis-à-vis the People's Republic of China.

The two Chinas after recognizing in 1992 the "status quo" of the real existence of two regimes and governments, but accepting by consensus the existence of a single, indivisible China, accelerated the pace of trade, investments and movement of people, despite they are still far from starting to even discuss a peace treaty. After that the relationship between the two Chinas has worsened a lot, currently the situation is chaotic.

the assassination of president lincoln was just one part of a larger plot to decapitate the federal government of the u.s. after the civil war. the first reaction to lincoln’s death was disbelief. then it quickly changed to grief. abraham lincoln’s death created an outpouring of grief from citizens in both the north and the south.

explanation:

lincoln was the first u.s. president to be assassinated. president abraham lincoln, america’s civil war leader, was assassinated just five days after confederate general robert e. lee surrendered his army at appomattox court house, ending the four-year war between the states. on the evening of april 14, 1865, lincoln was attending a performance of our american cousin at ford’s theatre in washington, d.c. john wilkes booth – a 26-year old actor, confederate sympathizer, and white supremacist – slipped into the presidential box and shot lincoln in the head. john wilkes booth and his conspirators had initially planned to kidnap lincoln to save the confederate states. but as the confederacy faltered, booth’s thoughts turned to murder. booth may have decided to act on his hatred after lincoln endorsed giving the right to vote to african-american men who had served in the union army.
