The American revolution - The American Revolution led to genuinely democratic politics becoming possible in the former colonies. In fact, the most important immediate consequence of America declaring independence was the creation of written state constitutions in 1776 and 1777.
French Revolution- The House of Bourbon is a French Dynasty that had ruled France for over 400 years. Its reign was disrupted by the French Revolution. Monarchy was abolished in France in 1792 and replaced with the Republican form of Government. Although the Bourbon monarchy was restored after the downfall of Napoleon Bonaparte in 1815, it lasted till only 1830 when it was finally overthrown in the July Revolution
Haitian revolution- The Haitian Revolution established the country of Haiti, ended French designs on the New World and led to a racial panic in the United States.
South American- the goals of the revolutions of equality and unity largely went unfulfilled. The fierce sense of Independence that had led to victory over colonial overlords, would cause divisions between the new nations and destroy Simon Bolivar's dreams of a Gran Columbia in South America. Soon after Independence, the unworldly reigns of government were grabbed by men who did not share the sense of equality that had ignited the revolutions.
Mexican revolution- The Mexican Revolution sparked the Constitution of 1917 which provided for separation of Church and state, government ownership of the subsoil, holding of land by communal groups, the right of labor to organize and strike and many other aspirations. Like most constitutions, it was a statement of what the delegates wanted for Mexicans and not what could be put in place immediately. Obregón thought the pace of reform was too slow under Carranza; he revolted and soon after the President was assassinated. Obregón himself was elected President in 1920, reformed land holding in Morelos and Yucatan, and worked to improve Mexico’s financial situation. Obregón was reelected in 1928, only to be killed by a supporter of the pro-Catholic opposition before he took office.
