For example, the Bill of Rights was not ratified by Massachusetts, Georgia and Connecticut, till 1939, but 2/3rds of the state ratified it in 1791. Why did Massachusetts, Georgia and Connecticut ratified the bill of Rights in 1939? The 150th anniversary of the passage by Congress of the Bill of Rights would be 1939, so those three states, which had been in the Union when the amendment was proposed, finally ratified it. Yes, officially the Bill of Rights did NOT become effective till 1791 when Virginia ratified the Bill of Rights but Congress had passed it in 1789 and sent the Bill of Rights to the States in 1789.

the following states had more to do with local in state politics then any real issue:
Maryland Mar 29, 1941
Virginia Feb 21, 1952
Alabama Sep 8, 1953
Florida May 13, 1969
South Carolina Jul 1, 1969
Georgia Feb 20, 1970
Louisiana Jun 11, 1970
North Carolina May 6, 1971
Mississippi Mar 22, 1984
http://www.usconstitution.net/constamrat.html#BoRPlease the note the following state REJECTED the Amendment, Georgia on Jul 24, 1919; by Alabama on Sep 22, 1919; by South Carolina on Jan 28, 1920; by Virginia on Feb 12, 1920; by Maryland on Feb 24, 1920; by Mississippi on Mar 29, 1920; by Delaware on Jun 2, 1920; and by Louisiana on Jul 1, 1920.
Most amendments are passed within a few years of Congressional approval, but it took from 1789 to 1992 to get 2/3rds of the states to approve what is now called the 27th Amendment (It was actually the Second amendment passed by Congress, the Bill of Rights followed, but the Bill of Rights were ratified almost soon afterward become the First through tenth amendments, while the proposed First and Second amendments lingered on for years).
What is now the 27th Amendment was ratified by several states in the early 1790s, by Ohio during a Congressional pay grab in 1873, but then took off on its own after Maine ratified it in 1983, finally getting 2/3rds vote in 1992.
Side note: the proposed first amendment governed the number of Congressmen per population, and that the number of Congressmen in Congress could NOT drop below a certain number once that number had been reached. It is now considered moot since we have 435 congressional members in the House.
