Problem: Background: Emiliano Zapata Salazar (Spanish pronunciation: [emi'ljano sa'pata]; 8 August 1879 - 10 April 1919) was a leading figure in the Mexican Revolution, the main leader of the peasant revolution in the state of Morelos, and the inspiration of the agrarian movement called Zapatismo. Zapata was born in the rural village of Anenecuilco in Morelos State, where peasant communities were under increasing pressure from the small landowning class who monopolized land and water resources for sugar cane production with the support of dictator Porfirio Diaz. Zapata early on participated in political movements against Diaz and the landowning hacendados, and when the Revolution broke out in 1910 he was positioned as a central leader of the peasant revolt in Morelos. Cooperating with a number of other peasant leaders he formed the Liberation Army of the South of which he soon became the undisputed leader.
Context: Meanwhile, the disintegration of the revolution outside of Morelos put pressure on the Zapatistas. As General Arenas had turned over to the constitutionalists, he had secured peace for his region and he remained in control there. This suggested to many revolutionaries that perhaps the time had come to seek a peaceful conclusion to the struggle. A movement within the Zapatista ranks led by former General Vazquez and Zapata's erstwhile adviser and inspiration Otilio Montano moved against the Tlaltizapan headquarters demanding surrender to the Carrancistas. Reluctantly, Zapata had Montano tried for treason and executed (Womack 1983-86).  Zapata began looking for allies among the northern revolutionaries and the southern Felicistas, followers of the Liberalist Felix Diaz. He sent Gildardo Magana as an envoy to communicate with the Americans and other possible sources of support. In the fall of 1917 a force led by Gonzalez and the ex-Zapatista Sidronio Camacho, who had killed Zapata's brother Eufemio, moved into the eastern part of Morelos taking Cuautla, Zacualpan and Jonacatepec.  Zapata continued his work to try to unite with the national anti-Carrancista movement through the next year, and the constitutionalists did not make further advances. In the winter of 1918 a harsh cold and the onset of the Spanish flu decimated the population of Morelos, causing the loss of a quarter of the total population of the state, almost as many as had been lost to Huerta in 1914. (Womack 311). Furthermore, Zapata began to worry that by the end of the World War, the US would turn its attention to Mexico forcing the Zapatistas to either join the Carrancistas in a national defense or to acquiesce to foreign domination of Mexico. In December 1918 Carrancistas under Gonzalez undertook an offensive campaign taking most of the state of Morelos, and pushing Zapata to retreat. The main Zapatista headquarters were moved to Tochimilco, Puebla, although Tlaltizapan also continued to be under Zapatista control. Through Castro, Carranza issued offers to the main Zapatista generals to join the nationalist cause, with pardon. But apart from Manuel Palafox, who having fallen in disgrace among the Zapatistas had joined the Arenistas, none of the major generals did (Womack 313-14). Zapata emitted statements accusing Carranza of being secretly sympathetic to the Germans (Womack 315). In March Zapata finally emitted an open letter to Carranza urging him for the good of the fatherland to resign his leadership to Vazquez Gomez, by now the rallying point of the anti-constitutionalist movement (Womack 319-20). Having posed this formidable moral challenge to Carranza prior to the upcoming 1920 presidential elections, the Zapatista generals at Tochimilco, Magana and Ayaquica, urged Zapata not to take any risks and to lay low. But Zapata declined, considering that the respect of his troops depended on his active presence at the front (Womack 320-22).
Question: When was he in control of his region?
Answer: 

Background: Shen Kuo (Chinese: Chen Gua ; 1031-1095), courtesy name Cunzhong (Cun Zhong ) and pseudonym Mengqi (now usually given as Mengxi) Weng (Meng Xi Weng ), was a Han Chinese polymathic scientist and statesman of the Song dynasty (960-1279). Excelling in many fields of study and statecraft, he was a mathematician, astronomer, meteorologist, geologist, zoologist, botanist, pharmacologist, agronomist, archaeologist, ethnographer, cartographer, encyclopedist, general, diplomat, hydraulic engineer, inventor, academy chancellor, finance minister, governmental state inspector, poet, and musician.
Context: The new Chancellor Cai Que (Cai Que ; 1036-1093) held Shen responsible for the disaster and loss of life. Along with abandoning the territory which Shen Kuo had fought for, Cai ousted Shen from his seat of office. Shen's life was now forever changed, as he lost his once reputable career in state governance and the military. Shen was then put under probation in a fixed residence for the next six years. However, as he was isolated from governance, he decided to pick up the ink brush and dedicate himself to intensive scholarly studies. After completing two geographical atlases for a state-sponsored program, Shen was rewarded by having his sentence of probation lifted, allowing him to live in a place of his choice. Shen was also pardoned by the court for any previous faults or crimes that were claimed against him.  In his more idle years removed from court affairs, Shen Kuo enjoyed pastimes of the Chinese gentry and literati that would indicate his intellectual level and cultural taste to others. As described in his Dream Pool Essays, Shen Kuo enjoyed the company of the "nine guests" (Jiu Ke , jiuke), a figure of speech for the Chinese zither, the older 17x17 line variant of weiqi (known today as go), Zen Buddhist meditation, ink (calligraphy and painting), tea drinking, alchemy, chanting poetry, conversation, and drinking wine. These nine activities were an extension to the older so-called Four Arts of the Chinese Scholar.  According to Zhu Yu's book Pingzhou Table Talks (Ping Zhou Ke Tan ; Pingzhou Ketan) of 1119, Shen Kuo had two marriages; the second wife was the daughter of Zhang Chu (Zhang Chu ), who came from Huainan. Lady Zhang was said to be overbearing and fierce, often abusive to Shen Kuo, even attempting at one time to pull off his beard. Shen Kuo's children were often upset over this, and prostrated themselves to Lady Zhang to quit this behavior. Despite this, Lady Zhang went as far as to drive out Shen Kuo's son from his first marriage, expelling him from the household. However, after Lady Zhang died, Shen Kuo fell into a deep depression and even attempted to jump into the Yangtze River to drown himself. Although this suicide attempt failed, he would die a year later.  In the 1070s, Shen had purchased a lavish garden estate on the outskirts of modern-day Zhenjiang, Jiangsu province, a place of great beauty which he named "Dream Brook" ("Mengxi") after he visited it for the first time in 1086. Shen Kuo permanently moved to the Dream Brook Estate in 1088, and in that same year he completed his life's written work of the Dream Pool Essays, naming the book after his garden-estate property. It was there that Shen Kuo spent the last several years of his life in leisure, isolation, and illness, until his death in 1095.
