Why was Spain angered by Jackson's actions?

Answer 1

Spain was angered by Andrew Jackson's actions during the First Seminole War in 1818, when he led military incursions into Spanish Florida without official approval. His aggressive tactics resulted in the seizure of Spanish forts and the execution of British subjects, which was viewed as a violation of Spanish sovereignty. This bold move heightened tensions between the United States and Spain, ultimately leading to negotiations that culminated in the Adams-Onís Treaty of 1819, where Spain ceded Florida to the U.S.
