What can be inferred from the passage about the African Americans in the 1970s?

Jesse Jackson fought for the rights of African Americans
during the civil rights movement of the 1960s. Later on
he became involved in politics and world affairs.
Jackson joined the civil rights movement when he was a
student. In 1965, he began working for a civil rights
group led by the famous Martin Luther King, Jr. In 1971,
Jackson founded the group People United to Save
Humanity (PUSH). This group helped African Americans
to get jobs and to open businesses. In 1984, he founded
the National Rainbow Coalition (NRC) to help all kinds
of people, not just African Americans. Jackson ran for
President of the United States in 1984 and 1988. While
he did not win either time, he did better than any other
African American presidential candidates who had come
before him. Jackson also gained a lot of attention for his
role in world affairs. He spoke out against apartheid
(separation of the races) in South Africa and took part in
peace talks in the Middle East. He also worked with
several countries to free US citizens being held as
prisoners.
