Answer:
Modern period or modern era
Step-by-step explanation:
Modern period is the name for the historical epoch, that is, the period of world history that followed the Middle Ages, whose tradition traditionally dates back to 1492, or is related to the Columbus discovery of America. Part of the historian, however, takes the year 1453, or the fall of Constantinople, to start the new century. In its broadest sense, the New Age is described as a period that continues to this day.
In the narrower sense, this means the period ending with the October Revolution of 1917 and the First World War (1914–1918). The period that follows it is called Recent Times or Contemporary History.
