LaFayette did not appear again prominently in public life until 1787, when he took his seat in the
Assembly of Notables. He demanded, and he alone signed the demand, that the king convoke the
Estates-General, thus becoming a leader in the
French Revolution. In 1788, he was deprived of his active command. In 1789, Lafayette was elected to the Estates-General, and took a prominent part in its proceedings. He was chosen vice-president of the
National Assembly, and on
July 11, 1789 proposed a declaration of rights, modeled on
Thomas Jefferson's Declaration of Independence in 1776.
On July 15, the second day of the new regime, La Fayette was chosen, by acclamation, colonel-general of the new
National Guard of Paris. He also proposed the combination of the colours of Paris, red and blue, and the royal white, into the famous
tricolour cockade and flag of modern France (
July 17). For the succeeding three years, until the end of the constitutional limited-monarchy in 1792, he played a significant role in the course of the Revolution. He rescued
Marie Antoinette from the hands of the populace in October 1789, as well as many others who had been condemned to death. He briefly resigned his commission, but was soon induced to resume it.
In the
Constituent Assembly he pleaded for
religious tolerance, popular representation, the establishment of trial by
jury, the gradual emancipation of slaves,
freedom of the press, the abolition of arbitrary imprisonment and of titles of
nobility, and the suppression of privileged orders. He drafted the
Declaration of the Rights of Man and of the Citizen which was adopted by the Assembly. In February 1790, he refused the supreme command of the National Guard of the kingdom.
Lafayette and other constitutional limited-monarchists who supported the Revolution in its early years founded the "Society of 1789", which afterwards became the
Feuillants Club, taking a position between Royalist supporters of
absolute monarchy and liberalist groups such as the
Jacobins and
Cordeliers. Lafayette took a prominent part in the celebration of
July 14, 1790, the first anniversary of the
storming of the Bastille. After suppressing a riot in April 1791 he again resigned his commission, and was again compelled to retain it. Louis XVI's deceptive
flight to Varennes undermined the position of the constitutional limited-monarchists, especially Lafayette himself who, as Commander of the National Guard, had had the responsibility to keep the King secure. Shortly after, on
July 17, 1791, a large crowd gathered at the
Champ de Mars to sign a petition calling for the overthrow of the monarchy. Earlier the crowd beheaded two vagrants found sleeping under the Nation's Altar that the mob mistook for spies, the crowd then fired twice on the National Guard and pelted them with a hail of rocks, after martial law was ordered by
Jean-Sylvain Bailly, the
Mayor of Paris, when the crowd was ordered to disperse, and when they did not, Lafayette ordered the National Guard to open fire and arrest the assassins in the crowd. About 50 people were killed in what became known as the "Massacre of the Champ de Mars", which decisively marked the end of the alliance between constitutional limited-monarchists and Jacobins which were now controlled by radicals like
Jean-Paul Marat and
Georges Danton. On the occasion of the proclamation of the constitution (
September 18, 1791), Lafayette tried to retire into private life. This did not prevent his friends from proposing him for the mayoralty of Paris in opposition to
Jérôme Pétion de Villeneuve.
In December 1791, Lafayette was placed in command of three armies formed on the eastern frontier to attack
Austria. He was nevertheless opposed to the further advance of the Jacobin party, intending eventually to use his army for the restoration of a Constitutional, limited monarchy out of respect for the authentic Christian nature of Louis XVI. During this time printed attacks against Lafayette, especially from
Jean-Paul Marat were at a crescendo. On
August 19, 1792, the Assembly declared him a traitor and
Georges_Danton took control of the National Guard. Lafayette took refuge in the neutral territory of
Liège, where he was taken and held as a prisoner of state for five years, first in
Prussia and afterwards in Austrian prisons (1794–1797 in Olmutz, now
Olomouc, in spite of intercession by the United States. During this time the
Anglophile Holy Roman Emperor
Francis II ruled. Francis II was opposite in political outlook from former Emperor
Joseph II who was pro-American and pro-Lafayette but died too early in 1790 and is known as "The Poor Man's Emperor", and an anti-feudal, reformist.(SEE The Hapsburgs by D.G.McGuigan,1966, Chapter IX) Very large subsidies were paid by the British Empire to Austria during this time. Several letters from Lafayette's wife state that the reason for Lafayette's prolonged imprisonment was the machinations of
Pitt the Younger. Napoleon, however, was forced by the
Directory (which was pro-Lafayette at that time), and stipulated in the preconditions of the
Treaty of Campo Formio (1797) that La Fayette be released. He was not allowed to return to France by Napoleon who increasingly seized more power. Lafayette, after his wife's pleading to Napoleon, returned in 1799; in 1802 he voted against the
life consulate of Napoleon, and in 1804, against the
imperial title.
