A bit of housekeeping, plus an opportunity to show off some flag designs Carolina is a federation of seven states, all of which are self-governing and share sovereignty with the federal government. Six of the states are located on the North American mainland, while the state of the Bahamas is an archipelagic state, covering the 14,000 square kilometres of the Lucayan Archipelago to the southeast of Georgia in the Atlantic Ocean. At the time of the creation of the Dominion of Carolina in 1858, there were the six states of Albemarle, Clarendon, Georgia, Tennessee, Alabama and Mississippi, all of which were former British American colonies. The Bahamas joined the dominion in 1911 as the seventh state. Under the Constitution of Carolina, the states have plenary legislative power except on matters reserved for the federal or imperial parliaments, however since the 1960s, the Carolinian federal government has amended the constitution to remove several powers from the states, notably voting laws and electoral redistricting, as well as control over state education and healthcare providers. The Bahamas are a notable exception, and retain significant control of local issues compared to the mainland states. The shift from a confederal model of the early constitution to the more unitary system of the late 20th century coincided with the Civil Rights movement, where some state governments were reluctant to end racial segregation, and the federal and imperial governments took steps to ensure compliance with the 1978 Civil Rights Acts.
