Royal baby paving way for a long line of male monarchs
The birth of a future king means a return to a "long unbroken line of male rule", a royal historian said.
Kate Williams said the British tend to prefer queens, who are often viewed as more exciting than "dreary old" kings, on the throne.
But with three generations of kings waiting in line after Elizabeth II, it could be many years before Britain sees another female monarch.
Dr Williams said: "We'll have a long unbroken line of male rule which is what we've usually had. That's why queens really stick out."
"I think the British like it when they have women on the throne. They're different. They're exciting, instead of dreary old men," she added.
