How did threats to the southern identity lead to the secession of the south

The main cause of southern succession was the US 's inability to solve the issue of slavery at national level.

Explanation:

The primary cause of the civil war was that the southern states desired to preserve the institution of slavery. Northerners opposed to the expansion of slavery .

Some opposed it due to moral reasons and others felt that slave labor was unfair. When Abraham Lincoln was elected as president in 1960 seven southern states seceded from the Union.

The secessionists claimed that according to constitution every state has right to leave the union.

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.
