In the case of Brown vs. the Board of Education of Topeka, the Supreme Court ruled that segregation in public schools was unconstitutional.

Explanation:

Brown v. Board of Education is a Supreme Court ruling published on May 17, 1954, which declared racial segregation in public schools unconstitutional. A complementary judgment on the same case was published on May 31, 1955: the two judgments are, for this reason, also cited as Brown I and Brown II. This ruling is arguably the most important of Warren's court decisions. From a technical point of view, the Brown judgment is applicable only to the public education system of the states; however the ruling in Bolling v. Sharpe, less known and published on the same day as Brown, also extends the obligation to the federal government.
