Thurston and Sanford B. Dole – the first Americans attempting to overthrow a foreign government under the auspices of a United States government officer. Apart from his work as a politician and diplomat, he was also a journalist, author, minister and newspaper publisher. He founded the Republican Party in Maine and served as Maine State Senator.
