The Shape of Things to Come

H.G. Wells'  The Shape of Things to Come (1933) is a "future history" novel presented as a manuscript from the future, chronicling humanity's path from global chaos in the mid-20th century (WWII, economic collapse, chemical warfare) towards a scientific, rational world state by the 21st century, advocating for global unity and scientific progress over nationalism and conflict, despite its dark predictions and utopian ideals.
