Originally a lawyer working on frontier cases across British America, Claiborne moved to New Orleans following the British capture of it. Claiborne did not agree with most of Governor-General Andrew Jackson's policies. Claiborne created the Whig Party, which supported the supremacy of parliament over the Governor-General, civil rights, modernization, and the end of slavery. Today, the Whig Party continues to be a major political party, and Claiborne is regarded as a Founding Father of Louisiana.
