Final answer:
During the Royal period in Georgia, which followed the Trustee period, a royal governor was established to govern the colony, marking the primary difference between the two periods.
Step-by-step explanation:
The true statement regarding the difference between the Trustee period and the Royal period in Georgia's colonial history is that C) The Royal period saw the establishment of a royal governor in Georgia. During the Trustee period, which lasted from 1732 to 1752, Georgia was governed by a Board of Trustees based in London, with no governor or legislative body within the colony. In contrast, after the collapse of the Trustee system in 1752, Georgia became a royal colony with a series of royal governors appointed on behalf of the king.
Furthermore, during the Trustee period, slavery and alcohol were outlawed in the colony - a decision in part due to the threat of Spanish Florida and the desire to maintain Georgia as a military buffer. However, by the 1750s, the economic difficulties and pressures from groups including the "Malcontents" led to the legalizing of slavery in Georgia just prior to the transition to the Royal period.
