Q1: In order to understand what "city proper" means in England, we must first understand the concept of a city proper in general. The term "city proper" refers to the central urban area or core of a larger metropolitan area. It typically includes the historical or administrative center of the city, often defined by its boundaries or administrative divisions. In England, the concept of city proper can vary depending on the specific city or region you are referring to.

To determine what "city proper" means in a specific context in England, you can refer to official city boundaries or administrative divisions set by local authorities. These boundaries may be defined by legal, historical, or administrative reasons and can differ between cities.

Q2: The Great Fire of London occurred in 1666. At that time, the population of London was approximately 80,000. The fire broke out in the city proper, which accounted for about one-sixth of the total population of London.

To obtain this information, you can consult historical records, books, or online resources that provide data on the population of London during that period.
