On October 10, 1865, the Constitutional Convention met in Tallahassee to nullify the Ordinance of Secession of 1861 and adopt a new constitution for the State of Florida.  The new constitution went into effect on November 7, 1865, without being submitted to the people for ratification.  The Constitution of 1865 was never fully effective.  Federal military forces remained in command of the state until July, 1868, when a new constitution was written.

The series contains the 1865 Constitution for the State of Florida adopted by the members of the Constitutional Convention in 1865.  The 67-page document is handwritten.  There are no proceedings to the 1865 Constitutional Convention in the Archives.
