How did John Brown's actions in Kansas and at Harper's Ferry illustrate anti-slavery feelings at the
time?

John Brown was the embodiment of Radical Abolitionism. It wasn't what many people had in mind, but it certainly made a great news story in which fear had risen up more in the south.

Explanation:

John Brown was a radical abolitionist and went arguably insane since he kind of failed at anything he tried. He kickstarted years of fighting and death known as "Bleeding Kansas" and then raided an armory at Harper's Ferry. He tried to use violent means in order to end slavery in the south. This put the south at the near-breaking point.

the andes or andean mountains (spanish: cordillera de los andes) are the longest continental mountain range in the world, forming a continuous highland along the western edge of south america. this range is about 7,000 km (4,300 mi) long, about 200 to 700 km (120 to 430 mi) wide (widest between 18° south and 20° south latitude), and of an average height of about 4,000 m (13,000 ft). the andes extend from north to south through seven south american countries: venezuela, colombia, ecuador, peru, bolivia, chile and argentina.
