In 1524, the famous Italian navigator, Giovanni da Verrazzano was the first European to visit any part of what is now Rhode Island. He came to what is now Block Island and named it “Luisa” after Louise of Savoy, Queen Mother of France. Verrazzano described Luisa as “about the size of the Island of Rhodes”. When the founders of the Colony of Rhode Island and Providence Plantations surveyed the land, they thought that Aquidneck Island was the place. A mistake occurred in 1614, when Luisa was charted by the Dutch explorer Adriaen Block, after whom Luisa was renamed by the Dutch West India Company; however, their motives in doing so are unknown.The official explanation by the State of Rhode Island is that Adriaen Block named the area “Roodt Eylandt” meaning “red island” in reference to the red clay that lined the shore, and that the name was later anglicized when the region came under British rule

The official name is State of Rhode Island and Providence Plantations, a state in the New England region of the northeastern United States of America.

Despite its name, most of the state of Rhode Island lies on the North American mainland. Providence Plantations refers to the mainland, while Rhode Island was the 17th and 18th century name for Aquidneck Island (now composed of the city of Newport, and the towns of Middletown and Portsmouth).

Here’s some history from the Rhode Island web site – hope it helps:

When we were in Jr High we took a field trip to Rhode Island to look at the mansions. They were incredible but as far as voting and that other stuff I have no idea.
