Explanation:
When it comes to Mexico and democracy within this country, there have been many changes during their existence since their independence in 1821. The reason México never established a long term democracy, is because there were many invasions and that made a country weaker than it should have been. Because of that, Mexico does not have a constant, stable constitution. The change was pretty solid back in the 1910 when the constitution of that year was established, and has not been changed, ever since.
