Kentucky was initially Kentucky County in Virginia. It achieved statehood and was admitted to the Union on June 1, 1792; see the list of governors of Virginia for the period before statehood. There have been 57 governors, serving 61 distinct terms.
An unelected group proclaimed Kentucky's secession from the Union on November 20, 1861, and it was annexed by the Confederate States of America on December 10, 1861. The Confederate government elected two governors (listed separately), but it never held much control over the state, and the main line of governors was preserved.
Steve Beshear is the 61st and current (2013) governor, having served since December 11, 2007. Isaac Shelby was 1st and 5th Governor of Kentucky.
