The monarch who began the American Revolution was George III. The cause: taxes after a successful war. Britain had won the Seven Years’ War in 1763, but was deeply in debt as a result. This gave them a pretext to tax the American colonists--without representation in Parliament. The colonists justly protested this act of usurping God-given liberties and begged the British to cease. After years of unanswered and slighted petitions, lawful armed interposition was required on Lexington Green.
Louis XVI and Taxes
The monarch who began the French Revolution was Louis XVI. The cause: taxes. The reason is a little different than the American War for Independence, but one reason was the debt on France because of winning the Bourbon War, which includes the American Revolution and other theaters of war (the French finances were also in trouble after the Seven Years’ War). The other reason was the excessive spending of the French court, especially blamed on Queen Marie-Antoinette. The French hated the Austrians, having fought them for 200 years, and Marie-Antoinette was not only an Austrian, but the daughter of the late Austrian Empress, Maria Theresa. Her spending and nationality inflamed the French against her until at last they revolted against the high taxes and stormed the Bastille.
The king's heart is in the hand of the LORD, as the rivers of water: he turneth it whithersoever he will. (Proverbs 21:1, KJV)
