All of these factors play a big role in territoriality, but in modern times, the leading ones are the economic factor (as a primary), and the political (close behind it). Nowadays everything is dictated by economy, so it plays the most important part in territoriality. People tend to be pleased when they have enough money and their own property, and the other factors are not so important. The economic factor is the basis for the political one, because the politics are based on economics, so people do not pay attention to politics while they are standing well economically. The environmental and ethnic factors, are primarily used as an instrument for the realization of some interest by the two other factors nowadays, they are a very mighty tool, but are used and are very influential when the other two, especially the economics are not working well.
