Perhaps the single most fundamental and important question a person could ask about Arthur is, Did he exist? This is the foundation on which all other questions about the man are constructed (such as ‘Who was his wife?’, ‘Where did he live?’, ‘Did he have descendants?’).
There is no universal consensus on this issue, but scholars generally fall into two main camps. One of these is the idea that there most likely was a historical military leader named Arthur at the core of the stories. The opposing theory is that Arthur was actually a figure of mythology or folklore, but then he came to be ‘historicized’ as the centuries went on.
