The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The contribution of the international situations has contributed to the development of constitutions in that specific moments in history have been the ones that have moved people to change their form of government in order to create one new government that guarantee the protection and the conditions to grow and prosper in peace.
Those were the cases of the United States and México, for instance.
Both nations had to live many years under the oppression and injustices of a European monarchy to organize themselves and start revolutionary movements that derived in their independence from that monarchies. In the case of the United States, they got independence from Great Britain. In the case of México, from Spain.
After the Revolutionary War of Independence in which the Conteinental Army led by General George Washington, defeated the English troops, the United States decided to have their own form of government and came up with the Articles of Confederation.
These articles proved to have some limitations and that is why the delegates of teh states met at the Constitutional Convention of 1787 in the city of Philadelphia, Pennsylvania, to create their new form of government under the principles of a Constitution.
Some similar happened in México when the Mexican army led by Agustín de Irurbudide defeated the Spanish Army and created some Constitutions until they finally signed the Constitution of the United States of México, in Quéretaro, on February 5, 1917.
