Article: In 633 AD, Rashidun Arabs invaded Iran and conquered it by 651 AD, largely converting Iranian people from their indigenous faiths of Manichaeism and Zoroastrianism to Sunni Islam. Arabic replaced Persian as the official language, while Persian remained the language of both ordinary people and of literature. Iran became a major contributor to the Islamic Golden Age, producing many influential scientists, scholars, artists, and thinkers. Establishment of the Safavid Dynasty in 1501, converted the Iranian people from Sunni Islam to Twelver Shia Islam, and made Twelver Shia Islam the official religion of Iran. Safavid conversion of Iran from Sunnism to Shiism marked one of the most important turning points in Iranian and Muslim history. Starting in 1736 under Nader Shah, Iran reached its greatest territorial extent since the Sassanid Empire, briefly possessing what was arguably the most powerful empire at the time. During the 19th century, Iran irrevocably lost swaths of its territories in the Caucasus which made part of the concept of Iran for centuries, to neighboring Imperial Russia. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a constitutional monarchy and the country's first Majles (parliament). Following a coup d'etat instigated by the U.K. and the U.S. in 1953, Iran gradually became close allies with the United States and the rest of the West, remained secular, but grew increasingly autocratic. Growing dissent against foreign influence and political repression culminated in the 1979 Revolution, which led to the establishment of an Islamic republic on 1 April 1979.

Question: What year did the Rashidun Arabs conquer Iran?
Ans: 651 AD

Article: Copyright infringement disputes are usually resolved through direct negotiation, a notice and take down process, or litigation in civil court. Egregious or large-scale commercial infringement, especially when it involves counterfeiting, is sometimes prosecuted via the criminal justice system. Shifting public expectations, advances in digital technology, and the increasing reach of the Internet have led to such widespread, anonymous infringement that copyright-dependent industries now focus less on pursuing individuals who seek and share copyright-protected content online, and more on expanding copyright law to recognize and penalize as "indirect" infringers the service providers and software distributors which are said to facilitate and encourage individual acts of infringement by others.

Question: What can happen to people who commit copyright infringement on a mass-scale?
Ans: sometimes prosecuted via the criminal justice system

Article: In April 1758, the British concluded the Anglo-Prussian Convention with Frederick in which they committed to pay him an annual subsidy of 670,000. Britain also dispatched 9,000 troops to reinforce Ferdinand's Hanoverian army, the first British troop commitment on the continent and a reversal in the policy of Pitt. Ferdinand had succeeded in driving the French from Hanover and Westphalia and re-captured the port of Emden in March 1758 before crossing the Rhine with his own forces, which caused alarm in France. Despite Ferdinand's victory over the French at the Battle of Krefeld and the brief occupation of Dusseldorf, he was compelled by the successful manoeuvering of larger French forces to withdraw across the Rhine.

Question: Who did Ferdinand repel from Ha nover?
Ans: the French
