From this room on, the exhibit focuses on the 20th century.

In 1909, during the gubernatorial elections in the state of Morelos, a well-organized political opposition emerged. In the town of Villa de Ayala, a group led by schoolteacher Pablo Torres Burgos gathered. Among its members were Rafael Merino, Gabriel Tepepan, and Emiliano Zapata.

Upon learning of the Maderista uprising, they decided to establish contact with the revolutionary headquarters. Acting as their representative, Torres Burgos met with the Maderistas; the meeting was successful, and the formal organization of the uprising in Morelos began.

By August 1911, Francisco I. Madero arrived in Cuautla to meet with General Emiliano Zapata. Upon his arrival, Madero delivered a speech in which he praised the loyalty of the Zapatistas and referred to Zapata as a man of integrity and one of the bravest soldiers in the Liberation Army.
