The correct answer is False.
Step-by-step explanation
The New Orleans riots was an event that occurred during the year 1866 when a large group of white people attacked a peaceful demonstration of blacks who had won their freedom after the defeat of the Confederacy during the American Civil War. This fact resulted in a massacre since many of the whites who attacked free blacks were ex-combatants of the Confederate army and did not agree with the promulgation of the Black Codes, which gave the power to vote to black men. Therefore, it can be said that the New Orleans riots did not take place when the radicals met to rewrite the Constitution of the state of Louisiana. So the correct answer is False.
