Answer:
Persuasive words have had a significant effect on American history. They have been used to inspire, motivate, and mobilize people to take action and make change. For example, Martin Luther King Jr. used powerful rhetoric to mobilize the Civil Rights Movement and to advocate for racial equality. His "I Have a Dream" speech, delivered during the March on Washington in 1963, is widely considered one of the greatest speeches in American history. Similarly, Abraham Lincoln's speeches, particularly his Gettysburg Address, were instrumental in uniting the country during the Civil War and in laying the foundation for the abolition of slavery. These speeches still widely studied for their persuasive power and rhetorical techniques.
