Pirates of the Caribbean opened in Disneyland in 1967 and was the last attraction to be overseen by Walt Disney, although he sadly died before it opened. Versions of the ride can now also be found at the Magic Kingdom, Tokyo Disneyland and Disneyland Paris. The attraction has seen numerous changes over the decades, most notably the introduction of characters from the Pirates of the Caribbean films and the 2018 update transforming the popular red head in the auction scene into a pirate.
For a detailed history of the original attraction, check out David O'Neal's feature length documentary. I also recommend FreshBaked's "Secrets and History of Pirates of the Caribbean" and Park History's "The Differences between Disney's Pirates of the Caribbean".
