Information:  - Mexican muralism was the promotion of mural painting starting in the 1920s, generally with social and political messages as part of efforts to reunify the country under the post Mexican Revolution government. It was headed by the big three painters, Diego Rivera, José Clemente Orozco and David Alfaro Siqueiros. From the 1920s to about 1970s a large number of murals with nationalistic, social and political messages were created on public buildings, starting a tradition which continues to this day in Mexico and has had impact in other parts of the Americas, including the United States where it served as inspiration for the Chicano art movement.  - The Workers' and Peasants' Red Army (: RKKA, frequently shortened in Russian to ; KA, in English: Red Army also in critical literature and folklore of that epoch - Red Horde, Army of Work) was the army and the air force of the Russian Soviet Federative Socialist Republic, and after 1922 the Union of Soviet Socialist Republics. The army was established immediately after the 1917 October Revolution (Red October or Bolshevik Revolution). The Bolsheviks raised an army to oppose the military confederations (especially the various groups collectively known as the White Army) of their adversaries during the Russian Civil War. Beginning in February 1946, the Red Army, along with the Soviet Navy, embodied the main component of the Soviet Armed Forces; taking the official name of "Soviet Army", until its dissolution in December 1991.  - Leon Trotsky (; born Lev Davidovich Bronstein;  21 August 1940) was a Marxist revolutionary and theorist, a Soviet politician who engineered the transfer of all political power to the Soviets with the October Revolution of 1917, and the founding leader of the Red Army.  - Lázaro Cárdenas del Río (May 21, 1895  October 19, 1970) was a general in the Mexican Revolution and a statesman who served as President of Mexico between 1934 and 1940. He is best known for nationalization of the oil industry in 1938 and the creation of Pemex, the government oil company.  - The Mexican Communist Party (PCM) was a communist party in Mexico. It was founded in 1911 as the Socialist Workers' Party (PSO) by Manabendra Nath Roy, a left-wing Indian Bengali intellectual. The PSO changed its name to the Mexican Communist Party in November 1919, following the Bolshevik Revolution in Russia. It was outlawed in 1925 and remained illegal until 1935, during the presidency of the leftist Lázaro Cárdenas. The PCM later lost its registration in 1946 because it did not meet the new requirements of at least 30,000 registered members in at least 21 of Mexico's 31 states and the Federal District. It is not clear whether the party was unable to recruit enough members or whether, fearing repression, it refused to turn membership rolls over to the Secretary of the Interior, then in charge of elections.  - David Alfaro Siqueiros ( born José de Jesús Alfaro Siqueiros , December 29 , 1896 , in Chihuahua - January 6 , 1974 , in Cuernavaca , Morelos ) was a Mexican social realist painter , better known for his large murals in fresco . Along with Diego Rivera and José Clemente Orozco , he established `` Mexican Muralism . '' He was a Marxist - Leninist in support of Stalin and a member of the Mexican Communist Party who participated in an unsuccessful attempt to assassinate Leon Trotsky in May 1940 . His surname would normally be Alfaro by Spanish naming customs ; like Picasso ( Pablo Ruiz y Picasso ) and Lorca ( Federico García Lorca ) , Siqueiros used his mother 's surname . It was long believed that he was born in Camargo in Chihuahua state , but in 2003 it was proven that he had actually been born in the city of Chihuahua , but grew up in Irapuato , Guanajuato , at least from the age of six . The discovery of his birth certificate in 2003 by a Mexican art curator was announced the following year by art critic Raquel Tibol , who was renowned as the leading authority on Mexican Muralism and who had been a close acquaintance of Siqueiros . Siqueiros changed his given name to `` David '' after his first wife called him by it in allusion to Michelangelo 's David . Another factual confusion is the year of his birth : he was born in 1896 , but many sources state 1898 or 1899 .  - The Mexican Revolution was a major armed struggle that radically transformed Mexican culture and government. Although recent research has focused on local and regional aspects of the Revolution, it was a "genuinely national revolution." Its outbreak in 1910 resulted from the failure of the 35-year long regime of Porfirio Díaz to find a managed solution to the presidential succession. This meant there was a political crisis among competing elites and the opportunity for agrarian insurrection. Wealthy landowner Francisco I. Madero challenged Díaz in 1910 presidential election, and following the rigged results revolted under the Plan of San Luis Potosí. Armed conflict ousted Díaz from power and a new election was held in 1911, bringing Madero to the presidency.
