Question: Information:  - Francisco "Pancho" Villa (born José Doroteo Arango Arámbula; 5 June 1878  20 July 1923) was a Mexican Revolutionary general and one of the most prominent figures of the Mexican Revolution.  - The United Nations (UN) is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the United Nations is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict.  - 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.  - North Africa or Northern Africa is the northernmost region of Africa. The United Nations definition of "North Africa" includes seven countries and territories; Algeria, Egypt, Libya, Mauritania, Morocco, Sudan, Tunisia, and Western Sahara. The countries of Algeria, Morocco, Tunisia, and Libya are often collectively referred to as the Maghreb, which is the Arabic word for "sunset". Egypt lies to the northeast and encompasses part of West Asia, while Sudan is situated on the edge of the Sahel, to the south of Egypt.  - The Boxer Rebellion, Boxer Uprising or Yihequan Movement was a violent anti-foreign and anti-Christian uprising that took place in China between 1899 and 1901, towards the end of the Qing dynasty. It was initiated by the Militia United in Righteousness ("Yihetuan"), known in English as the "Boxers", and was motivated by proto-nationalist sentiments and opposition to imperialist expansion and associated Christian missionary activity.  - Edward Sinnott `` Tex '' O'Reilly ( 15 August 1880 -- 9 December 1946 ) was an American soldier of fortune who is said to have fought in ten wars under many flags . Initially serving in the U.S. Army in the Spanish -- American War and Philippine -- American War , as well as the Boxer Rebellion , he would claim to fight in Venezuela , Honduras and Nicaragua .

He became a writer , including as a reporter for the Associated Press . He wrote an autobiography , Roving and Fighting , and Lowell Thomas wrote Born to Raise Hell about him . The latter book has been reprinted and is distributed by The Long Riders ' Guild Press .  - The Spanish Civil War, widely known in Spain simply as The Civil War or The War, took place from 1936 to 1939 and was fought between the Republicans, who were loyal to the democratic, left-leaning and a relatively urban Second Spanish Republic in an alliance of convenience with the Anarchists, versus the Nationalists, a falangist, Carlist and a largely aristocratic conservative group led by General Francisco Franco. Although the war is often portrayed as a struggle between democracy and fascism, some historians consider it more accurately described as a struggle between leftist revolution and rightist counterrevolution. Ultimately, the Nationalists won, and Franco then ruled Spain for the next 36 years, from April 1939 until his death in November 1975.  - "Don" Miguel Primo de Rivera y Orbaneja, 2nd Marquis of Estella, 22nd Count of Sobremonte, Knight of Calatrava (January 8, 1870  March 16, 1930) was a dictator, aristocrat, and military officer who served as Prime Minister of Spain from 1923 to 1930 during Spain's Restoration era. He deeply believed that it was the politicians who had ruined Spain and that governing without them he could restore the nation. His slogan was "Country, Religion, Monarchy." Historians depict him as an inept dictator who lacked clear ideas and political acumen, and who alienated his potential supporters such as the army. He did not create a base of support among the voters, and depended instead on elite elements. His actions discredited the king and ruined the monarchy, while heightening social tensions that led in 1936 to a full-scale Spanish Civil War.  - The Rif War, also called the Second Moroccan War, was fought in the early 1920s between the colonial power Spain (later joined by France) and the Berbers of the Rif mountainous region. Led by Abd al-Karim, the Riffians at first inflicted several defeats on the Spanish forces by using guerrilla tactics and captured European weapons. After France's entry into the conflict and the massive landing of Spanish troops at Al Hoceima, Abd el-Karim surrendered to the French and was taken into exile. Despite victory, controversy in Spain over the conduct of the war led to a military coup by Gen. Miguel Primo de Rivera in 1923 and foreshadowed the Spanish Civil War of 193639.
