During the post-Byzantine period, the term "basileus", by the renewed influence of Classical writers on the language, reverted to its earlier meaning of "king". This transformation had already begun in informal usage in the works of some classicizing Byzantine authors. In the Convention of London in 1832, the Great Powers (the United Kingdom of Great Britain and Ireland, July Monarchy France, and Imperial Russia) agreed that the new Greek state should become a monarchy, and chose the Wittelsbach Prince Otto of Bavaria as its first king.
