Question: Timur was born in Transoxiana near the city of Kesh (modern Shahrisabz, Uzbekistan) some 80 kilometres (50 mi) south of Samarkand, part of what was then the Chagatai Khanate. His father, Taraqai, was a minor noble of the Barlas, a Mongolian tribe that had been turkified in many aspects. According to Gerard Chaliand, Timur was a Muslim, and he saw himself as Genghis Khan's heir. Though not a Borjigid or a descendent of Genghis Khan, he clearly sought to invoke the legacy of Genghis Khan's conquests during his lifetime.

It was in this period that Timur reduced the Chagatai khans to the position of figureheads while he ruled in their name. Also during this period, Timur and his brother-in-law Husayn, who were at first fellow fugitives and wanderers in joint adventures, became rivals and antagonists. The relationship between them began to become strained after Husayn abandoned efforts to carry out Timur's orders to finish off Ilya Khoja (former governor of Mawarannah) close to Tishnet. Timur began to gain a following of people in Balkh, consisting of merchants, fellow tribesmen, Muslim clergy, aristocracy and agricultural workers, because of his kindness in sharing his belongings with them. This contrasted Timur's behavior with that of Husayn, who alienated these people, took many possessions from them via his heavy tax laws and selfishly spent the tax money building elaborate structures. At around 1370 Husayn surrendered to Timur and was later assassinated, which allowed Timur to be formally proclaimed sovereign at Balkh. He married Husayn's wife Saray Mulk Khanum, a descendant of Genghis Khan, allowing him to become imperial ruler of the Chaghatay tribe. One day Aksak Temur spoke thusly: "Khan Zudei (in China) rules over the city. We now number fifty to sixty men, so let us elect a leader." So they drove a stake into the ground and said: "We shall run thither and he among us who is the first to reach the stake, may he become our leader". So they ran and Aksak Timur, as he was lame, lagged behind, but before the others reached the stake he threw his cap onto it. Those who arrived first said: "We are the leaders." ["But,"] Aksak Timur said: "My head came in first, I am the leader." Meanwhile, an old man arrived and said: "The leadership should belong to Aksak Timur; your feet have arrived but, before then, his head reached the goal." So they made Aksak Timur their prince.

Answer:

Problem: Khan was born on 15 July 1914 in Agra. He was among the four sons and three daughters of Khansaahib Ameer Ahmed Khan and Mehmoodah Begum. His father, a police inspector, was inspired by the reformist thinking of Syed Ahmed Khan. In his early age, Khan's mother introduced him to the poetry of Maulana Hali and Muhammad Iqbal, the sermons of Abul Kalam Azad, and the Sufist philosophy of Rumi.

The Comilla Model (1959) was Khan's initiative in response to the failure of a Village Agricultural and Industrial Development (V-AID) programme that was launched in 1953 in East and West Pakistan with technical assistance from the US government. V-AID remained a government-level attempt to promote citizen participation in the sphere of rural development. Khan launched the project in 1959 on his return from Michigan, and developed a methodology of implementation in the areas of agricultural and rural development on the principle of grassroots-level participation. Initially, the aim was to provide a development model of programmes and institutions that could be replicated across the country. Advisory support in this respect was provided by experts from Harvard and Michigan State Universities, the Ford Foundation, and USAID. Practical help was also sought from Japan to improve the local farming techniques. Comilla Model simultaneously addressed the problems that were caused by the inadequacy of both local infrastructure and institutions through a range of integrated programmes. The initiatives included the establishment of: a training and development centre; a road-drainage embankment works programme; a decentralized, small scale irrigation programme; and, a two-tiered cooperative system with primary cooperatives operating in the villages, and federations operating at sub-district level. After Khan's departure from Comilla, the cooperative's model failed in independent Bangladesh because only a few occupational groups managed to achieve the desired success. By 1979, only 61 of the 400 cooperatives were functioning. The model actually fell prey to the ineffective internal and external controls, stagnation, and diversion of funds. This prompted the subsequent scholars and practitioners in microfinance, such as Muhammad Yunus of Grameen Bank and Fazle Hasan Abed of BRAC, to abandon the cooperative approach in favour of more centralised control and service delivery structures. The new strategy targeted the poorest villagers, while excluding the 'less poor'. However, Khan's leadership skills during the course of his association with the project remained a source of inspiration for these leaders, as well as other participatory development initiatives in the country.
