Final answer:
Sir William Berkeley is acknowledged as the best Proprietary Governor, who was involved in the establishment of Fort Nassau and renamed it Charles Town in 1670 to honor Charles II.
Step-by-step explanation:
The Best Proprietary Governor and the Founding of Charles Town
The best Proprietary Governor who built Fort Nassau and renamed it Charles Town was Sir William Berkeley. Berkeley was the Governor of Virginia and, as a Lord Proprietor, played a significant role in the establishment and development of the Carolinas.
In 1670, amidst the colonization efforts under the reign of Charles II, the colonists named their new settlement Charles Town to honor the king. This action was part of the broader endeavors by the Lords Proprietors, including Berkeley, to promote the benefits of settling in Carolina despite challenges such as countering rumors that the area was an unhealthy place to live.
It is worth noting that Dutch merchants established an earlier Fort Nassau near present-day Albany, but this is not connected to the establishment of Charles Town. The establishment of Charles Town as a fort and a proprietary colony signifies one of the key developments in early American colonial history.
The year 1670 marks the founding of Charles Town, which was eventually developed into the city now known as Charleston, South Carolina. This event underscores the importance Charles II and his royalist supporters placed on colonization, which resulted in the creation of several proprietary colonies during his reign.
