Final answer:
Louis XIV built the Palace of Versailles, Napoleon Bonaparte fought at the Battle of Waterloo, and Henry IV ruled before the French Revolution.
Step-by-step explanation:
The three correctly paired French monarchs with a major achievement of their reign are:
- Louis XIV - Palace of Versailles: During his reign, Louis XIV built the Palace of Versailles, a symbol of his absolute power and the grandeur of the French monarchy. The palace contained 700 rooms, extensive gardens, and lavish decoration.
- Napoleon Bonaparte - Battle of Waterloo: One of Napoleon's major achievements was his military success, but the Battle of Waterloo in 1815 marked his final defeat and the end of his reign.
- Henry IV - French Revolution: This is an incorrect pairing. Henry IV ruled France from 1589 to 1610, long before the French Revolution that took place in the late 18th century.
