Andrew Marr explores the Age of Revolution. In the 17th- and 18th-centuries, people across the world rose up in the name of freedom and equality against the power of the church and monarchy. In America, people fought a war to be free from British rule. In France, bloody revolution saw the king and aristocracy deposed. And in Haiti, the slaves revolted against their masters. The world was also gripped by a scientific revolution, sweeping away old dogmas and superstition. Galileo revolutionised the way we saw humanity's place in the universe, while Edward Jenner used science to help save the lives of millions.
