At present, zoning laws regulate those zones which can be used for developing commercial activity or for building residential areas; they also specify the placement, size and height of the structure.
But zoning laws were first designed to protect some districts by means of building walls around these cities. Outside the walls, poor people lived in deplorable and dangerous conditions, while inside this protection it was possible to find civic and religious places as well as the majority of the population.
Many things were invented, for example the printing press which helped print copies of the bible.
Many new techniques were also invented especially artistic techniques, such as perspective, shading and many more.
Scientists also discovered a lot of things like they used to believe the universe in Heliocentric (Earth is in the center of the universe) but they discovered that its actually sun-sentric.
Many new inventions were made and used which led to more conclusions that are still known and believed by the people today.
eg. The microscope, telescope, printing press...etc
