What subject matter would you paint if you were a realist painter working in the 1800s?

Though never a coherent group, Realism is recognized as the first modern movement in art, which rejected traditional forms of art, literature, and social organization as outmoded in the wake of the Enlightenment and the Industrial Revolution. Beginning in France in the 1840s, Realism revolutionized painting, expanding conceptions of what constituted art. Working in a chaotic era marked by revolution and widespread social change, Realist painters replaced the idealistic images and literary conceits of traditional art with real-life events, giving the margins of society similar weight to grand history paintings and allegories. Their choice to bring everyday life into their canvases was an early manifestation of the avant-garde desire to merge art and life, and their rejection of pictorial techniques, like perspective, prefigured the many 20th-century definitions and redefinitions of modernism.
