A Wilhelm II succession could provoke a constitutional crisis

What would change if a succession crisis made Wilhelm II king of the United Kingdom before July 1914?

Parliament would probably bypass him rather than accept a German autocrat as Britain's constitutional monarch, and an attempt to enforce the claim could itself cause war.

The scenario requires a catastrophic succession event because Wilhelm stood behind numerous British heirs. Even if he inherited, he could not simply merge Britain and Germany: the British crown operated through a constitutional monarchy, while he exercised much greater personal authority as Kaiser. Parliament would probably pass an act bypassing him rather than accept that clash of offices. If Wilhelm tried to enforce what he regarded as his rightful claim, the succession dispute could become another route to war before the crisis of 1914.
