Answer:
the Brown v. Board of Education Supreme Court decision in 1954.
Step-by-step explanation:
The Brown v. Board of Education of Topeka was a litigation or court case between Oliver Brown and the Board of Education in which the justices of the Supreme Court unanimously ruled (9-0) that racially segregating children in public schools was unconstitutional because it violates the Equal Protection Clause of the Fourteenth Amendment (14th) of the Constitution of the United States of America.
In this scenario, Brady's grandmother often tells him about her memories of growing up black in the South in the 1960s. One of her favorite memories revolved around her school becoming integrated, allowing both Black and white students to attend school together. The landmark event which allowed this to be possible was the Brown v. Board of Education Supreme Court decision in 1954.
