After the third Estate pamphlet, Sieyes had major influence on his
fellow French men. He suggested that the National Assembly reunite under the Third Estate and strongly disapproved of the
confiscation of Church lands. Sieyes was then elected fortnightly president of the Constitution Assembly. When Sieyes took
up this post he was excluded from the Legislative Assembly. After this Sieyes disengaged from the political scene only to
reappear to vote for the death of King Louis XVI. Sieyes did not dislike the King or the monarchy itself, however, he did
dislike the uncontrolled power of the monarch. He felt that the monarch’s power should be controlled by a constitution
of the government. After the King’s execution, Sieyes once again disengaged from politics, enabling him to simply live
through the Rein of Terror.
After the Reign of Terror, Abbe Sieyes decided to go on a diplomatic
mission. This mission sent him to The Hague. He helped draw up a treaty between the French and Batavian republics. After this
The Directory offered him the position of Director of the Republic, however, he promptly declined the offer because he vehemently
resented the constitution of 1795. Three years later Sieyes went to the court of Berlin in attempt to persuade Prussia to
ally with France against, he was nevertheless offered Director of France. He diligently accepted on may 9, 1799 at the age
of 51. Although he accepted this position he plotted to overthrow the Directory. He attempted to undermine the constitution
without immediate success.
With the success of the Napoleon Bonaparte campaign, Sieyes stopped
plotting ways to overthrow the Directory. Sieyes completed the French Constitution only to have it completely revised by Napoleon.
The new copy was named the Constitution of the Year VII, which became the foundation of the French Constitution.
Sieyes essentially defended Napoleon in arbitrary and illegal acts that allowed Bonaparte to rid himself of any "leading Jacobins".
After this Abbe Sieyes went into retirement with no intent on returning to the political scene.
Sieyes was restless and did not stay in his retirement did not last long. Sieyes soon became
the first senator of France. Eventually Sieyes achieved a quiet retirement. He then left France only to return after the July
Revolution in 1830. Emmanuel Joseph Sieyes lived six more years and then quietly died in 1836 at the old age of 88.
