• I will gladly take answers to any or all. :)

• Answer:

  Usually the country become independent when it's free from any external control that might be controlling it. most worlds' countries become indepedent after colonialist rule was replaced by country's people government. This people must fight against the colonial rule to gain control over there own land. If this people aren't strongh enough, the colonialists will never leave the country, therefore the country will never be independent as long as it's control by this foreigners.
