Proprietary colony: A proprietary colony was a type of British colony mostly in North America and the Caribbean in the 17th century.  In the British Empire, all land belonged to the ruler, and it was his prerogative to divide.  Therefore, all colonial properties were partitioned by royal charter into one of four types: proprietary, royal, joint stock, or covenant.  King Charles II used the proprietary solution to reward allies and focus his own attention on Britain itself.  He offered his friends colonial charters which facilitated private investment and colonial self-government.  The charters made the proprietor the effective ruler, albeit one ultimately responsible to English law and the king.  Charles II gave New Netherland to his younger brother The Duke of York, who named it New York.  He gave an area to William Penn who named it Pennsylvania.

As a politician, Themistocles was a populist, having the support of lower-class Athenians, and generally being at odds with the Athenian nobility.  Elected archon in 493 BC, he convinced the polis to increase the naval power of Athens, a recurring theme in his political career.  During the first Persian invasion of Greece he fought at the Battle of Marathon (490 BC) and was possibly one of the ten Athenian "strategoi" (generals) in that battle.
