Kandahar was an important military and commercial city. This was a fort-city and there were conflicting claims about this between the Mughals and the Safavids of Iran. Initially, Kandahar was under Humayun. Two years after the death of Humayun Iran took possession of that city. In 1595 Akbar recaptured it. Although the Safavids had diplomatic ‘ relations with the Mughals, they continued to claim Kandahar. In 1613, Shah Jahan sent a diplomatic representative to the Court of Shah Abbas in Iran. The idea was to let the Mughals continue to have power over Kandahar. But the mission failed. In 1622, the Persian Army attacked Kandahar. The Mughal army was not battle-ready to defend the place. They were forced to give up Kandahar to Safavids. All efforts to recapture it later failed.
