Maritime transportation became less important to developed countries
in the 1950s, planes became a more popular mode of transportation, so traveling by sea was not as popular to developed countries
It depends on what type of government the country is. Take an example, Great Britain (England, Britain, whatever it is called.) is a monarchy, which means that they have royal families... like how we have the president. (in the U.S at least) It can also be dependent on what the country decides to do, or the president decides. I hope this helps!
