Answer:
The main purpose of the southern Manifesto was to oppose the supreme court ruling on Brown vs board of education case
Step-by-step explanation:
The southern Manifesto was a document written in 1956 in the 84th united states congress. this was a document/Manifesto that condemned the Ruling of the supreme court judgement on Brown vs Board of education, the ruling brought about the Racial integration of blacks and whites in public places, and the Manifesto was strongly against such.
The 19 senators and 77 members of the house of representatives that signed the document/resolution called on states not to implement the mandate of the court on the Ruling because the resolution saw the ruling as an abuse of "Judicial powers"
