Abdali invaded the Mughal Empire seven times from 1748 to 1767. According to Jaswant Lal Mehta, Durrani aroused the Afghans "religious passions" to fire and "sword into the land of infidels India." He crossed the Khyber pass in December 1747 with 40,000 troops for his first invasion of India. He occupied Peshawar without any opposition. He first crossed the Indus River in 1748, the year after his ascension - his forces sacked and absorbed Lahore. The following year , the Mughal ruler was induced to cede Sindh and all of the Punjab including the vital trans Indus River to him, in order to save his capital from being attacked by the forces of the Durrani Empire. Having thus gained substantial territories to the east without a fight, Durrani and his forces turned westward to take possession of Herat, which was ruled by Nader Shah's grandson, Shah Rukh. The city fell to the Afghans in 1750, after almost a year of siege and bloody conflict; the Afghan forces then pushed on into present-day Iran, capturing Nishapur and Mashhad in 1751. Durrani then pardoned Shah Rukh and reconstituted Khorasan, but a tributary of the Durrani Empire. This marked the westernmost border of the Afghan Empire as set by the Pul-i-Abrisham, on the Mashhad-Tehran road.

In a game that various analysts considered a potential Super Bowl XLVII preview, the 7-1 Bears faced the also 7-1 Houston Texans on Sunday Night Football, in a game waged in the rain. The first half proved disastrous for Chicago, as Kellen Davis had the ball stripped by former Bear Danieal Manning, and recovered by Texans linebacker Tim Dobbins. Shayne Graham later kicked a 20-yard field goal to give Houston the first points of the game. On Chicago's next possession, Michael Bush fumbled, and the Texans recovered again. The Texans drive wouldn't last long, as Tim Jennings would intercept Matt Schaub. However, the Bears failed to take advantage of the turnover, as Jay Cutler's pass would get intercepted by Manning. A quarter later, Jennings once again intercepted Schaub, which set up a Robbie Gould 51-yard field goal. Later in the quarter, Justin Forsett broke a 25-yard run to the Bears 3-yard line, which set up Arian Foster's 2-yard touchdown catch. Late in the first half, Cutler was hit by Dobbins, giving him a concussion, which sidelined him for the rest of the game, and was replaced by Jason Campbell. With less than two minutes left in the third quarter, Gould hit a 24-yard field goal to draw the Bears within four points, but Graham would make a 42-yarder to increase the deficit to seven with less than five minutes left in the game. Gould had attempted a 48-yard field goal earlier in the fourth quarter, but the ball hit the left upright. The loss snapped Chicago's six-game winning streak, the longest since their seven-game streak in 2006, and dropped Chicago to a 7-2 record, and 0-3 all-time against the Texans.

In late 1920, the Persian Soviet Socialist Republic in Rasht was preparing to march on Tehran with "a guerrilla force of 1,500 Jangalis, Kurds, Armenians and Azerbaijanis", reinforced by the Bolsheviks' Red Army. This fact, along with various other disorders, mutinies and unrest in the country created "an acute political crisis in the capital." By 1921, the ruling Qajar dynasty of Persia had become corrupt and inefficient. The oil-rich nation was somewhat reliant on the nations of Britain and Russia for military and economic support. Civil wars earlier in the decade had threatened the government, and the only regular military force at the time was the Cossack Brigade. The Qajar shah in 1921 was Ahmad, who had been crowned at the age of eleven. He was considered to be a weak, incompetent ruler, especially after British, Russian and Ottoman occupations of Persia during World War I. In 1911, when the capital city, Tehran, had been seized by the Russians, armed Bakhtiaris tribemen, rather than Iranian regular troops, expelled the invaders. This further diminished the government's reputation, rendering it almost powerless in time of war. Britain, which played a major role in Persia, was dismayed by the Qajar government's inability to rule efficiently. This inefficiency was the background of a power struggle between Britain and Russia, each nation hoping to control Persia. On 14 January 1921, the British General Ironside chose to promote Reza Khan, who had been leading the Tabriz battalion, to lead the entire brigade. About a month later, under British direction, Reza Khan's 3,000-4,000 strong detachment of the Cossack Brigade reached Tehran.
