In history, what two things did not sound like they happened in the same era, but happened at the same time?

It was something that seemed to have happened many years ago, but it happened in a very short period of time. It was the kind that made people very surprised and afraid. Just give me a few examples.

Answer 1

In Chinese history, there were two things that happened at the same time. These two things were:

1 Han and Tang Dynasties: The Han and Tang Dynasties were two neighboring dynasties, but they spanned a very long period of time and existed together for more than 1000 years. The Han Dynasty was founded in 206 B.C. and the Tang Dynasty in 618 A.D., but there was no obvious time difference between them.

2. The Renaissance and the Industrial Revolution: The Renaissance and the Industrial Revolution were two seemingly unrelated periods, but they happened at the same time. The Renaissance occurred in the 14th century and the Industrial Revolution occurred in the 18th century. Although there was no direct connection between these two periods, their emergence and development had a profound impact on modern society.
