MCMXLV

MCMXLV is the Roman numeral representation of the year 1945. This year marked the end of World War II, a global conflict that spanned from 1939 to 1945. The war concluded with the surrender of Nazi Germany in May and the Empire of Japan in August of that year. The cessation of hostilities brought about significant geopolitical shifts, including the division of Germany, the rise of the United States and the Soviet Union as superpowers, and the establishment of the United Nations.

In 1945, the Manhattan Project, a top-secret research and development undertaking by the United States with the support of the United Kingdom and Canada, culminated in the creation of the first atomic bombs. These weapons were subsequently used on the Japanese cities of Hiroshima and Nagasaki in August, leading to Japan's unconditional surrender and ushering in the nuclear age. The post-war period saw the beginning of decolonization movements in various parts of the world and the start of the Cold War, a period of geopolitical tension between the Soviet Union and the Western Bloc. The year 1945 is therefore a pivotal point in modern history, signifying both immense destruction and the dawn of a new global order.
