Disney Stars on Parade debuted at Disneyland Paris in March 2017 as part of the park's 25 anniversary celebrations. Unlike its predecessor, Disney Magic on Parade, it consists of all new flats to the resort. There are some familiar faces, however - the Lion King and Peter Pan floats were recycled from Tokyo Disneyland's "Jubilation" parade, together with a replica of the hugely popular Maleficent fire-breathing dragon from Walt Disney World.
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".
