Emmanuel Joseph Sieys , most commonly known as the Abb Sieys , was a French Roman Catholic abb, clergyman and political writer. He was one of the chief of political theorists of the French Revolution, and also played a prominent role in the French Consulate and First French Empire. His 1789 pamphlet What is the Third Estate became the de facto manifesto of the Revolution, helping to transform the EstatesGeneral into the National Assembly in June 1789. In 1799, he was among the instigators of the coup dtat ofBrumaire , which brought Napoleon Bonaparte to power. He also coined the term sociologie in an unpublished manuscript, and made significant theoretical contributions to the nascent social sciences.
Sieys was born onMay 1749 as the fifth child of Honor and Annabelle Sieys in the town of Frjus in southern France. Sieys father was a local tax collector who made a humble income, and while the family had some noble blood, they were commoners. Sieys first education came by way of tutors and of the Jesuits. He also spent some time at the collge of the Doctrinaires of Draguignan. Sieys originally wanted to join the military and become a soldier, but his frail health, combined with his parents piety, led him instead to pursue a religious career. The vicargeneral of Frjus offered aid to Sieys, because he felt he was obliged to his father.
