In U.S. history, the Adams-Onis Treaty was a treaty signed in 1819 by the U.S. government and the Spanish government with the purpose of establishing a border between the U.S. and new Spain but also with the purpose of annexing the territory of Florida to the U.S. as this was owned by Spain until 1819. This bilateral treaty ended with disputes for the territory that had developed in previous decades by establishing clear borders between both nations and defining the territories that belonged to each one. Therefore, the territory the United States gained from Spain as a result of the Adams-Onis Treaty was Florida that was ceded by Spain to the U.S. in 1819 when the treaty was signed.
British Prime Minister Winston Churchill's first speech as prime minister was a remarkable speech in their history. Because at that time they were on war with Nazi forces. In his speech he motivated the British people to stand strong against Nazi forces by addressing the Nazis as 'monstrous tyranny'. He said his aim is to win over this monstrous tyranny, who committed serious war crime. So the 'monstrous tyranny' refers to the Nazi forces of Germany.
