Development

Development of a province affects how many people the province can house, how fast a province can be captured, how many rebels will pop up in a revolt and how much tax is given from that province.

'''

Advantages of high development:

Higher taxes, you can house more people in that province and that province will be harder to capture by enemy forces, rebels may also become weaker as development grows (because they are usually wealthier).

'''

Disadvantages of high development:

Higher development causes people to consume more luxuries, otherwise the lack of resources can crash a bit of your income.

Development can be lowered and raised in different ways: To raise development you would need buildings such as townhall/constables in that province, policies such as Deforestation and Irrigation and leader traits such as builder, raising development has its own disadvantages and advantages stated above.

To lower development you would need leader traits such as thrifty or policies such as high property tax and extensive poverty aid.

Advantages of Lower development:

Less food and luxury requirement which means less resources needing to be used, rebels are also weaker in there and easier to capture.

Disadvantages of Lower development:

Your enemy can also capture your lands easier, your tax income is also significantly lowered and population housing is also lowered.
