Q: Context_1 : The Gur-i Amir or Guri Amir (Uzbek: "Amir Temur maqbarasi, Go'ri Amir" , Persian: ), is a mausoleum of the Asian conqueror Timur (also known as Tamerlane) in Samarkand, Uzbekistan. It occupies an important place in the history of Persian-Mongolian Architecture as the precursor and model for later great Mughal architecture tombs, including Gardens of Babur in Kabul, Humayun's Tomb in Delhi and the Taj Mahal in Agra, built by Timur's Persianised descendants, the ruling Mughal dynasty of North India. It has been heavily restored. Context_2 : Musakhel (Urdu: ), all hilly and green, is hard to be traced in the historical descriptions as there is no isolated account of the area available.

In 1505 AD, the Mughals conquered the province of Kandahar and held it till 1559 AD when the Safavid Kings of Persia acquired it. The Mughals regained the province in 1595 AD but lost it again in 1622 AD, to the Safavid Kings of Persia. This time, the Safavids, conferred the government of Pishin and its tribal dependencies upon Sher Khan Tarin. He, after 7 years, refused to submit to the governor of Kandahar and became semi-independent, but had to retreat later on. In 1709 AD, the Afghan inhabitants rose under Mir Wais Ghilzai and established the Ghilzai power in Kandahar. The Ghilzai power was terminated by Nadir Shah in 1737 AD. After the assassination of Nadir Shah in 1747 AD, the first democratic government was established in Kandahar by the Afghans as they elected Ahmed Shah Durrani as their ruler.
