The United States Constitution was signed on September 17, 1787, at Independence Hall in Philadelphia, Pennsylvania. This signing was the culmination of a four-month-long Constitutional Convention, which began in May of the same year. The convention was convened to address the shortcomings of the Articles of Confederation, which had established the first national government but lacked the power to carry out essential functions, such as raising revenue or conducting diplomatic relations.
The signing on September 17, 1787, marked the endorsement of the Constitution by 39 delegates representing 12 states. Rhode Island was the only state that did not send delegates to the convention. The delegates who signed the Constitution ranged in age from 26-year-old Jonathan Dayton to 81-year-old Benjamin Franklin. Franklin, who had to be carried to the sessions in a sedan chair due to his infirmity, summed up the sentiments of those who signed despite their reservations, stating that while he did not approve of every part of the Constitution, he accepted it as the best option at the time.
The signing of the Constitution was an extraordinary achievement, as the delegates representing wildly different interests and views crafted compromises to create a powerful central government while protecting the prerogatives of the states. The Constitution laid out a framework for the nation's federal government, delineating the functions of its three branches: legislative, executive, and judicial. The signing ceremony included signatures, a brief declaration of successful completion, and a formulaic dating of its adoption.
The delegates who signed the Constitution had diverse backgrounds, with virtually all of them having taken part in the American Revolution. Seven had signed the Declaration of Independence, and at least 29 had served in the Continental forces.

The founders bypassed state legislatures and called for special ratifying conventions in each state, with ratification by 9 of the 13 states enacting the new government.

The youngest was 26, the oldest 81
The United States Constitution was signed on September 17, 1787, at Independence Hall in Philadelphia, Pennsylvania. Of the 74 delegates chosen to attend, 55 attended the sessions, and only 39 signed the Constitution. Jonathan Dayton, aged 26, was the youngest to sign the Constitution, while Benjamin Franklin, aged 81, was the oldest.
The delegates' ages reflected the wide range of perspectives and experiences represented at the Constitutional Convention. Jonathan Dayton, the youngest signer, brought a youthful perspective to the proceedings, while Benjamin Franklin, the oldest at 81, contributed a wealth of knowledge and experience. Despite their age difference, both individuals played a crucial role in shaping the Constitution and ensuring its unanimous support from the delegations from each state.
Jonathan Dayton, the youngest signer, was born in 1760 and represented New Jersey at the Constitutional Convention. He had a keen interest in politics and law, and despite his young age, he had already established himself as a lawyer and served in the Continental Congress. Dayton went on to have a prominent political career, eventually becoming a United States Senator and playing a significant role in the early years of the republic.
Benjamin Franklin, the oldest signer at 81, was a renowned polymath and one of the Founding Fathers of the United States. By the time of the Constitutional Convention, Franklin had a long and distinguished career as a scientist, inventor, writer, and diplomat. He had served as a delegate to the Continental Congress and played a crucial role in the American Revolution. Despite his advanced age and infirmity, Franklin's presence at the Convention carried great symbolic weight, and his support for the Constitution was instrumental in securing its adoption.
The age gap between the youngest and oldest signers of the Constitution, spanning over five decades, demonstrates the unity and inclusivity of the delegates who came together to shape the future of the nation. Their collective effort resulted in the creation of a powerful central government that addressed the challenges facing the young country and laid the foundation for the United States as we know it today.

12 of 13 states were represented
The United States Constitution was signed on September 17, 1787, at Independence Hall in Philadelphia, Pennsylvania. 39 delegates to the Constitutional Convention, representing 12 of the 13 states, endorsed the Constitution. Rhode Island was the only state that did not send any delegates to the convention.
The delegates were tasked with revising the existing government framework, which was laid out in the Articles of Confederation. However, they ended up drafting a completely new constitution, creating a powerful central government. The delegates represented a wide range of interests and views, and their task was not an easy one. They debated competing proposals from May to July 1787 before turning over their plans to a Grand Committee, which produced the final document we now know as the Constitution.
The signing of the Constitution was an extraordinary achievement, as it required the unanimous support of the delegations from each state. To achieve this unanimity, the formula "Done in convention by the unanimous consent of the states present..." was devised. This formula appears in the Constitution's closing protocol, along with signatures, a brief declaration of successful completion, and a statement of adoption by the states present.
The delegates who signed the Constitution ranged in age from 26-year-old Jonathan Dayton to 81-year-old Benjamin Franklin. Franklin, who had to be carried to the sessions in a sedan chair due to his infirmity, summed up the sentiments of those who signed, acknowledging their imperfect approval of the document but accepting it as the best option.
