The earliest known historical milestone is the Neolithic revolution around 10,000 B.C., when humans across the world began to cultivate food for the first time, allowing for rapid population increases. In 27 B.C. Augustus Caesar became the first emperor of Rome, establishing the greatest empire the world had ever known.
Around A.D. 30, Jesus of Nazareth began a ministry that evolved into the world's largest religion, Christianity, which eventually spread to every corner of the globe. Almost six centuries later, in the year 610, the Prophet Muhammad founded the world's second largest religion, Islam.
From the 14th century to the 17th, Europe underwent the Renaissance, a cultural and social revolution that saw the invention of the printing press, which allowed more people to become educated than ever before. This evolution of ideas and society culminated in 1760 with the beginning of the Industrial Revolution, which gave birth to the Enlightenment and the modern world.
The 20th century saw two major world wars. World War I was fought from 1914 to 1918 and marked the end of colonial empires throughout the world, while World War II, fought from 1939 to 1945, brought the United States of America to the forefront of international influence and power.
