Refugees in the world

We all know that there are a large number of refugees in the world :
Iraqis, Syrians, Palestinians, Chechens, Pakistan etc.
But why I wonder :  Is it because of war or humanitarian status or political reasons ...
ok lts take a look about the 
  Definition of a Refugee :
 Article 1A(2) stipulates that:
  the term ‘refugee’ shall apply to any person who […] owing to a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group or political opinion, is outside the country of his nationality and is unable or, owing to such fear, is unwilling to avail himself of the protection of that country; or who, not having a nationality and being outside the country of his former habitual residence as a result of such events, is unable or, owing to such fear, is unwilling to return to it.
But what about people who  born refugees Because of their parents who were refugees, Why do people or governments treat them as refugees
I lived  and i stell living this experience  ,,,,,   but i just wander about the Governments that about peace 
if thay are really want peace Why not treat refugees with respect , Why makes them feel that they are refugees , But the fact they are not refugees because they created this situation
They talk about refugees and their attempts to integrate them into communities but thay doing the Opposite
The answer is clear :
tthay Always want to go to the bank to take money at the expense of the refugees ,  It is a good investment all the family will cautions children and the number is growing  and the Bank pay more
And can control the people and taking liberties on the pretext that the refugees dangerous , And impose emergency law on On their people pretext of th refugees
I think that the first how use this method the Arabs governments :) Where I live :)
In the end peace to all
