Poorter

Poorter () is an historical term for a type of Dutch, or Flemish, burgher who had acquired the right to live within the walls of a city with city rights.
In the Dutch Republic, this "poorterrecht" or "poorterschap" (citizenship) could be gained by paying a sum of money to, and registering, with the magistrate of the city. The payment of money was to prove that one was not poor, and that one could maintain a household. There were also religious restrictions, and numerous cities forbade Jews from attaining citizenship until the French Revolution. An oath was also taken. Some cities also had "grootburgers" (grand burghers), who received more rights than normal citizens, but had to pay a higher price to acquire it.
The city would be surrounded by a city wall, and a moat, which offered safety, and protection, of a certain level, to its citizens. At nightfall, the city gates would be closed by the gate watch. The Keys to the city were handed to the Burgemeester, and returned again the next day.
The entire citizenry of a city was sometimes called the Poorterij.
