The 20th century saw two major conflicts called the World Wars ๐. World War I happened from 1914 to 1918, and involved many countries, including the
United Kingdom, France, and Germany. Trench warfare was common, where soldiers fought from long, muddy trenches. World War II followed, from 1939 to 1945, and involved even more nations, with events like the attack on Pearl Harbor and the D-Day invasion ๐ข. The war ended with the dropping of atomic bombs on Hiroshima and Nagasaki, which affected how countries viewed warfare. These massive wars shaped modern history, changed politics, and led to the creation of the United Nations!
