Rhode Island did not send a representative to the Constitutional Convention of 1787, becoming the only former colony to not attend the meeting. Rhode Island was very distrustful of the power of a centralized federal government and decided to boycott the convention altogether.
Rhode Island also become the last of the former colonies to approve the Constitution and officially join the United States. In 1788, it rejected the document by popular referendum. However, in 1790, the future state's governing body called a convention, which passed the Constitution by a margin of two votes, mainly due to the inclusion of the Bill of Rights.
