President Lincoln followed the plan subsequently completed by Johnson. The original (Pierpont) government of Virginia was recognized and supported. Similar governments were established in Tennessee, Louisiana, and Arkansas, and an unsuccessful attempt was made to do so in Florida. The amnesty proclamation of December, 1863, offered to recognize any State government in the seceding States formed by one tenth of the former voters who should take the oath of loyalty and support of the emancipation measures. At the following session of Congress, the first bill providing for congressional supervision of the readmission of the seceding States was passed, but the President retained it without signing it until Congress had adjourned. At the time of President Lincoln's assassination Congress was not in session, and President Johnson had six months in which to complete the work. Provisional governors were appointed, conventions were called, the State constitutions were amended by the abolition of slavery and the repudiation of the war debt, and the ordinances of secession were either voided or repealed. When Congress met in December, 1865, the work had been completed, the new State governments were in operation, and the XIIIth Amendment, abolishing slavery, had been ratified by aid of their votes. Congress, however, still refused to admit their Senators or Representatives. The first action of many of the new governments had been to pass labor, contract, stay, and vagrant laws which looked much like a re-establishment of slavery, and the majority in Congress felt that further guarantees for the security of the freedmen were necessary before the war could be truly said to be over. Early in 1866 President Johnson imprudently carried matters into an open quarrel with Congress, which united the two thirds Republican majority in both Houses against him. The elections of the autumn of 1866 showed that the two thirds majorities were to be continued through the next Congress; and in March, 1867, the first Reconstruction Act was passed over the veto. It declared the existing governments in the seceding States to be provisional only; put the States under military governors until State conventions, elected with negro suffrage and excluding the classes named in the proposed XIVth Amendment, should form a State government satisfactory to Congress, and the State government should ratify the XIVth Amendment; and made this rule of suffrage imperative in all elections under the provisional governments until they should be readmitted. This was a semi-voluntary reconstruction. In the same month the new Congress, which met immediately on the adjournment of its predecessor, passed a supplementary act. It directed the military governors to call the conventions before September 1st following, and thus enforced an involuntary reconstruction.
