After the establishment of the Second Spanish Republic in 1931, Muñoz Seca was at the height of his career, though his dramatic output slowed. Major works during this period include "La voz de su amo" (1933), "Anacleto se divorcia" (1932), "La EME" (1934), and "La plasmatoria" (1935). Muñoz Seca was a royalist and friend of Alfonso XIII, and his plays "La oca" (1931) and "Jabalí" (1932) sharply criticized the Second Republic. In July 1936, after the outbreak of the Spanish Civil War, he was arrested in Barcelona; he was later transported to Madrid. A humorist to the end, he said to his court-martial, "You can take my hacienda, my land, my wealth, even—as you are going to do—my life. But there is one thing that you cannot take from me—the fear that I have!" On November 28, 1936, he was executed by a Spanish Republican Army firing squad in the Paracuellos massacre.
