When historians talk about the 16th century, they mean the years from 1501 to 1600. This might seem backwards at first: why isn't the 1500s called the 15th century? The reason is that we count centuries starting from year 1, not year 0. So the first century covered years 1 to 100, the second century covered 101 to 200, and so on. By that logic, the 16th century includes the 1500s.

The 16th century was a time of enormous change in Europe and around the world. This was the age of exploration, when European sailors like Magellan circumnavigated the globe and mapped previously unknown lands. It was also the century of the Renaissance in full bloom, when artists like Michelangelo and Leonardo da Vinci created masterpieces that still amaze us today. The Protestant Reformation began in 1517 when Martin Luther challenged the Catholic Church, changing Christianity forever. Shakespeare was born in this century and began writing his plays near the end of it.

Understanding centuries helps you place events in history and see how they connect. When you read that the printing press revolutionized Europe in the mid-1400s (15th century) and that its effects transformed society by the 1500s (16th century), you can picture how one development led to another across time.
