How did Nat Turner show resistance to slavery?

By starting a rebellion

Explanation:

On August 22nd, 1831, slave Nat Turner led a slave rebellion in Virginia. He believed that God chose him to lead his people into freedom. He started the rebellion with five like-minded people, but after two days, that number had grown to about 70 slaves.

The plan was to free as many slaves as possible by terrorizing Southampton County, Virginia. The plan was also implemented in some 48 hours, killing at least 57 white men, women and children. But then, local white men, aided by military forces, quelled the rebellion. Nat Turner managed to escape but was caught six weeks later. He was brought to court and convicted of organizing a rebellion and hanged in November 1831.

The so-called Nat Turner Rebellion scared many white people in the area. Even stricter laws were introduced for slaves and all efforts to abolish slavery were unsuccessful for a long time.
