One of the most important minority movements in the nation's history was the civil rights movement in the 1960s, led by African American civil rights leader D. Martin Luther King Jr. What can also mention the Cesar Chavez movement to improve the working conditions of farmers in the South of the United States. These movements achieved important things and caught people's attention although I don't think the nation has achieved full civil rights for all citizens in the country. I can explain this by mentioned the injustices acts country-wide regarding segregation based on racism and the many different incidents in which white people or the police had killed African American individuals in the streets of the United States.
It is too difficult to say what is needed to achieve equality for all because if that would be the case, it has already been reached. And that is not the case. But one of the first things at hand is to educate the younger generation on the importance of integration and the respect of the civil rights of every single citizen, no matter the color of its skin, gender, or nationality.
