Did the Adams-Onis Treaty end the second Seminole War?

No, the Adams-Onís Treaty did not end the Second Seminole War. The treaty, signed in 1819, primarily dealt with the cession of Florida from Spain to the United States and set boundaries between U.S. territories and New Spain. The Second Seminole War, which began in 1835, continued until 1842, well after the treaty was signed. The war was primarily a conflict over the removal of Seminole tribes from Florida, which was a separate issue from the territorial agreements established in the Adams-Onís Treaty.
