If you mean state conventions, then no, the 18th amendment was passed by these conventions, enacted Prohibition. However, a national convention has never been convened to approve an amendment.
It was initially the "Grand Convention" or "Philadelphia Convention", not the Constitutional Convention, as it had been called in 1787 ostensibly to amend the Articles of Confederation. But the result, nonetheless, was the new US Constitution.
The Constitution provides that an amendment may be proposed either by the Congress with a two-thirds majority vote in both the House of Representatives and the Senate or by a constitutional convention called for by two-thirds of the State legislatures. None of the 27 amendments to the Constitution have been proposed by constitutional convention. The Congress proposes an amendment in the form of a joint resolution. Since the President does not have a constitutional role in the amendment process, the joint resolution does not go to the White House for signature or approval. A proposed amendment becomes part of the Constitution as soon as it is ratified by three-fourths of the States (38 of 50 States).
The Fourteenth Amendment establish equal rights and protection to all United States citizens. It covered citizenship, protection, legality, and equality that hadn't been an issue at the Constitutional Convention.
both houses of Congress or by two thirds of the state legislatures. This method of proposing amendments is known as a constitutional convention. However, to date, no constitutional convention has been called through this method, and all 27 amendments to the Constitution have been proposed by Congress.
When a constitutional amendment has been ratified it means that the amendment had been passed or agreed upon by 3/4 of congress and is now being made a legal amendmen to our Constitution
Well, at the Constitutional Convention...he wasn't there. He was actually abroad as a diplomat. However, he was in the Continental Congress, and there (and if he'd been at the Convention) he represented Massachusetts.
Ratify
Wrong. Rarified means approved.
The authority to amend the constitution comes from Article V of the constitution. After congress proposes an amendment the Archivist of the United States is charged with the responsibility of ratification. The constitution provides that an amendment may be proposed by congress with two-thirds majority vote in both the house and senate or by a constitutional convention called by two-thirds of the state legislatures. None of the 27 amendments have been proposed by the convention method. The congress proposes an amendment in the form of a joint resolution. The president doesn't have a constitutional role so it doesn't go to him for approval.
It was initially the "Grand Convention" or "Philadelphia Convention", not the Constitutional Convention, as it had been called in 1787 ostensibly to amend the Articles of Confederation. But the result, nonetheless, was the new US Constitution.
The first method of amendment is the only one actually used so far. An amendment is proposed in the Congress and approved by at least two thirds of each house. It must then be ratified by three fourths of the states. Either of two methods of state ratification can be chosen by Congress: approval by the state legislatures or by a special convention in each state. The second method of amending the Constitution has never been used successfully since the original Constitutional Convention. If two thirds of the state legislatures approve of a convention for proposing amendments, any amendments coming out of the convention are submitted for ratification by the states. This has been tried several times in recent decades to advance amendments requiring a balanced budged, term limits and the like.
There are two ways to propose an Amendment to the US Constitution: 1. An amendment may be introduced and pass both houses of Congress (House of Representatives and the Senate) by a majority of at least two-thirds (66.7%) of a quorum (not necessarily 2/3 of the full body). 2. Or, a Constitutional Convention may be convened if two-thirds of the states' legislatures call for a convention. Once the convention is convened, any amendment may be introduced, discussed and voted on. Once an Amendment is proposed by either process above, then it must be Ratified by three-quarters (75%) of the states (currently 38), either by a vote of the state legislature or state convention.
