called for the destruction of the government under the Constitution, and the creation of a new state dedicated to the principles of the Declaration. On July 5, 1852, Frederick Douglass delivered a speech asking the question, "What to the Slave Is the Fourth of July?". The controversial question of whether to allow additional slave states into the United States coincided with the growing stature of the Declaration. The first major public debate about slavery and the Declaration took place during the Missouri controversy of 1819 to 1821. Anti-slavery Congressmen argued that the language of the Declaration indicated that the Founding Fathers of the United States had been opposed to slavery in principle, and so new slave states should not be added to the country. Pro-slavery Congressmen led by Senator Nathaniel Macon of North Carolina argued that the Declaration was not a part of the Constitution and therefore had no relevance to the question. With the abolitionist movement gaining momentum, defenders of slavery such as John Randolph and John C. Calhoun found it necessary to argue that the Declaration's assertion that "all men are created equal" was false, or at least that it did not apply to black people. During the debate over the Kansas–Nebraska Act in 1853, for example, Senator John Pettit of Indiana argued that the statement "all men are created equal" was not a "self-evident truth" but a "self-evident lie". Opponents of the Kansas–Nebraska Act, including Salmon P. Chase and Benjamin Wade, defended the Declaration and what they saw as its antislavery principles. John Brown's Declaration of Liberty In preparing for his raid on Harpers Ferry, said by Frederick Douglass to be the beginning of the end of slavery in the United States, abolitionist John Brown had many copies printed of a Provisional Constitution. (When the seceding states created the Confederate States of America 16 months later, they operated for over a year under a Provisional Constitution.) It outlines the three branches of government in the quasi-country he hoped to set up in the Appalachian Mountains. It was widely reproduced in the press, and in full in the Select Senate Committee report on John Brown's insurrection (the Mason Report). Much less known, as Brown did not have it printed, is his Declaration of Liberty, dated July 4, 1859, found among his papers at the Kennedy Farm. It was written out on sheets of paper attached to fabric, to
