That would be the 19th Century (also known as the 1800's). 1800-1899, or 1801-1900 if you want to be technical, were the years of the XIXth Century. X is the Roman numeral for ten, and IX is nine, so XIX = 19.
The 19th century was the years from 1801 to 1900. The 20th was the years from 1901 to 2000.
In the common calendar centuries are calculated from the year 1. There was NO year zero ion the common calendar, which confuses a lot of people. That means the first century lasted from 1 to 100, the second from 101 to 200, and so on. Following that pattern the century number can be calculated as follows: 1. Determine the starting year of the century. Regardless of a lot of misinformation out there, centuries ALWAYS start with the "1" year, so 1921 is in the century starting with 1901. 2. Remove the last 2 digits ('01') : 1901 -> 19 3. Add 1 to the remaining digit(s) to get the century : 19 + 1 = 20 So, 1921 was in the 20th century. What this means is that the LAST year of a century always ends in '00' and its first 2 digits are different from the rest of the years. That causes all sorts of problems. In fact, there was almost a universal mistake in 2000 because so many people insisted that 2000 was the first year of the 21st century. Scientists and calendar experts kept telling the world that 2000 was actually the LAST year of the TWENTIETH century but hardly anyone listened. Some historians checked old books and newspapers, and found that in 1900, for example, almost everyone knew that the 20th century had to wait until 1901. But then, there weren't radio and TV stations constantly giving out wrong information!
In the last century, there have been several notable pandemics, including the 1918 influenza pandemic, the 1957 H2N2 influenza pandemic, the 1968 H3N2 influenza pandemic, the HIV/AIDS pandemic beginning in the late 20th century, the H1N1 influenza pandemic in 2009, and the COVID-19 pandemic that started in 2019. Overall, these events highlight the recurring nature of pandemics and their significant impact on global health.
