The Stuarts, who, thanks to Henry VII marrying his daughter to a Scottish prince, had a legitimate claim to the English throne. What a time.
We have people trying to blow up the king, a king trying to rule without parliament, a civil war and a king without his head and finally a country without a king. Then, a King comes back, a Catholic king holds
office when a Catholic can't and parliament sends an invitation to a Dutch prince to come over and rule England.
In 1601, the estimated population of England (to the nearest ¼million) was 4 million people.
