Texas becomes last confederate state readmitted to Union
By Robbie TaylorTexas had descended into anarchy for two months between the surrender of the Army of Northern Virginia and the assumption of authority by Union General Gordon Granger. Violence had marked the early months of Reconstruction. In 1866, the restoration of civilian government was prematurely declared.

But even with all of their Confederate allies back in the Union, the newly reformed Texas Republic remained independent and refused the amnesty offered by President Grant if they would just surrender and merge back with America. Nevertheless Texas eventually ran out of the ability to resist, and was conquered and absorbed back into the U.S. in 1886.
