What influenced the rise of romanticism and realism, and what values and ideas were at the core of each movement?

During the latter part of the eighteenth century the drama in France had steadily declined from the glorious position which it had achieved in the reign of Louis XIV. The genius of Voltaire, by its stage-reforms and innovations, had partially stayed the downward movement in tragedy, and the philosophic Diderot had sought to substitute for mirthful comedy a new species--the serious--which should be an agent of social reform, and in fact the consummation of dramatic art as a mirror of life.

Classical tragedy had been weighted down by the artificiality of the court in every direction, and thus made a beautiful monster. The plays of the new style, vaguely called drames, were intended to be true to life and to inculcate the proper principles of society. The idea had already been advanced in the dreams of various social philosophers, but for obvious reasons no attempt had been made to reduce it to practice. Diderot, though an able writer in other departments, failed as a dramatist, but some who had adopted his idea had better success. The most remarkable dramatist of the period, however, was Beaumarchais, who boldly revived the old Spanish comedy of intrigue. He not only surpassed his predecessor in the skillful framing of plots, but drew his characters with peculiar truth. His dialogue was brilliant with flashes of wit, and his plays were charged with social satire. His Figaro, with its searchlight illumination of the old régime, became a warning beacon of the approaching Revolution. But taken altogether, the drama of this period is rather of historic interest than actual value. It consists of imitations of the great works of the classic age, themselves imitations of antiquity, or imperfect attempts at reform and extension. It became thoroughly mechanical and lost artistic value. "French tragedy," said Goethe, with not undue severity, "is a parody of itself."
