Input: History of India
Ahom Kingdom (12281826) was a kingdom and tribe which rose to prominence in present-day Assam early in the thirteenth century. They ruled much of Assam from the 13th century until the establishment of British rule in 1838. The Ahoms brought with them a tribal religion and a language of their own, however they later merged with the Hindu religion. From thirteenth till seventeenth century, repeated attempts were made by the Muslim rulers of Delhi to invade and subdue Ahoms, however the Ahoms managed to maintain their independence and ruled themselves for nearly 600 years.

What group repeatedly tried and failed to conquer the Ahom?
Output: Muslim rulers of Delhi

Input: John, King of England
The administration of justice was of particular importance to John. Several new processes had been introduced to English law under Henry II, including novel disseisin and mort d'ancestor. These processes meant the royal courts had a more significant role in local law cases, which had previously been dealt with only by regional or local lords. John increased the professionalism of local sergeants and bailiffs, and extended the system of coroners first introduced by Hubert Walter in 1194, creating a new class of borough coroners. John worked extremely hard to ensure that this system operated well, through judges he had appointed, by fostering legal specialists and expertise, and by intervening in cases himself. John continued to try relatively minor cases, even during military crises. Viewed positively, Lewis Warren considers that John discharged "his royal duty of providing justice ... with a zeal and a tirelessness to which the English common law is greatly endebted". Seen more critically, John may have been motivated by the potential of the royal legal process to raise fees, rather than a desire to deliver simple justice; John's legal system also only applied to free men, rather than to all of the population. Nonetheless, these changes were popular with many free tenants, who acquired a more reliable legal system that could bypass the barons, against whom such cases were often brought. John's reforms were less popular with the barons themselves, especially as they remained subject to arbitrary and frequently vindictive royal justice.

When was the system of coroners first introduced?
Output: 1194

Input: On the Origin of Species
Scientific readers were already aware of arguments that species changed through processes that were subject to laws of nature, but the transmutational ideas of Lamarck and the vague "law of development" of Vestiges had not found scientific favour. Darwin presented natural selection as a scientifically testable mechanism while accepting that other mechanisms such as inheritance of acquired characters were possible. His strategy established that evolution through natural laws was worthy of scientific study, and by 1875, most scientists accepted that evolution occurred but few thought natural selection was significant. Darwin's scientific method was also disputed, with his proponents favouring the empiricism of John Stuart Mill's A System of Logic, while opponents held to the idealist school of William Whewell's Philosophy of the Inductive Sciences, in which investigation could begin with the intuitive truth that species were fixed objects created by design. Early support for Darwin's ideas came from the findings of field naturalists studying biogeography and ecology, including Joseph Dalton Hooker in 1860, and Asa Gray in 1862. Henry Walter Bates presented research in 1861 that explained insect mimicry using natural selection. Alfred Russel Wallace discussed evidence from his Malay archipelago research, including an 1864 paper with an evolutionary explanation for the Wallace line.

Which school did opponents to Darwin's method support?
Output: the idealist school of William Whewell's Philosophy of the Inductive Sciences

Input: Federal Bureau of Investigation
Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)with which the FBI was heavily involvedbroke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.

When did the FBI begin investigating espionage?
Output:
1940s
