answer: 5th century AD
context: Title: Farrer Park address
  Passage: The Farrer Park address was an assembly of the surrendered Indian troops of the British Indian Army held at Farrer Park in Singapore on 17 February 1942, two days after the Fall of Singapore.  The assembly was marked by a series of three addresses in which the British Malaya Command formally surrendered the Indian troops of the British Indian Army to Major Fujiwara Iwaichi representing the Japanese military authority, followed by transfer of authority by Fujiwara to the command of Mohan Singh, and a subsequent address by Mohan Singh to the gathered troops declaring the formation of the Indian National Army to fight the "Raj", asking for volunteers to join the army.
  Title: Jiffs
  Passage: Jiffs was a pejorative term used by British Intelligence, and later the 14th Army, to denote soldiers of the Indian National Army after the failed First Arakan offensive of 1943.  The term is derived from the acronym "JIFC", short for Japanese-Indian (or -inspired) fifth column.  It came to be employed in a propaganda offensive in June 1943 within the British Indian Army as a part of the efforts to preserve the loyalty of the Indian troops at Manipur after suffering desertion and losses at Burma during the First Arakan Offensive.
  Title: Hyderabad State
  Passage: Hyderabad State (   ), also known as Hyderabad Deccan, was an Indian princely state located in the south-central region of India with its capital at the city of Hyderabad.  It is now divided into Telangana state, Hyderabad-Karnataka region of Karnataka and Marathwada region of Maharashtra.  The state was ruled from 1724 until 1948 by a hereditary Nizam who was initially a Mughal governor of the Deccan before becoming independent.  Hyderabad gradually became the first princely state to come under British paramountcy signing a subsidiary alliance agreement.  After the Partition of India, Hyderabad signed a standstill agreement with the new dominion of India, continuing all previous arrangements except for the stationing of Indian troops in the state.  However, with the rise of militant razakars, India found it necessary to station Indian troops and invaded the state in September 1948 to compel the Nizam.  Subsequently, the Nizam signed an instrument of accession, joining India.
  Title: King's Commissioned Indian Officer
  Passage: A King's commissioned Indian officer (KCIO) was an Indian officer of the British Indian Army who held a full King's commission after training at the Royal Military College, Sandhurst, in England, as opposed to the Indian commissioned officers (ICOs), who were trained at the Indian Military Academy at Dehra Dun, and the Viceroy's commissioned officers (VCOs), who were treated in almost all respects as commissioned officers, but who only had authority over Indian troops.  KCIOs were introduced in the early 20th century under the Indianisation process.  They were equivalent in every way to the British officers holding a King's commission (known in India as King's commissioned officers, or KCOs).  They held the same ranks, and unlike VCOs had authority over British troops.  In fact, most KCIOs served on attachment to a British unit for a year or two early in their careers.

  Passage: Bala Hissar is an ancient fortress located in the city of Kabul, Afghanistan.  The estimated date of construction is around the 5th century AD.  Bala Hissar sits to the south of the modern city centre at the tail end of the Kuh-e-Sherdarwaza Mountain.

  Title: Battle of Kohima
  Passage: The Battle of Kohima was the turning point of the Japanese U Go offensive into India in 1944 during the Second World War.  The battle was fought in three stages from 4 April to 22 June 1944 around the town of Kohima in Nagaland in northeast India.  From 3 to 16 April, the Japanese attempted to capture Kohima ridge, a feature which dominated the road by which the besieged British and Indian troops of IV Corps at Imphal were supplied.  By mid-April, the small British and Indian force at Kohima was relieved.  From 18 April to 13 May, British and Indian reinforcements counter-attacked to drive the Japanese from the positions they had captured.  The Japanese abandoned the ridge at this point but continued to block the Kohima–Imphal road.  From 16 May to 22 June, the British and Indian troops pursued the retreating Japanese and reopened the road.  The battle ended on 22 June when British and Indian troops from Kohima and Imphal met at Milestone 109, ending the Siege of Imphal.
  Title: Feast of Christ the King
  Passage: The Solemnity of Our Lord Jesus Christ, King of the Universe, commonly referred to as the Feast of Christ the King, is a relatively recent addition to the Western liturgical calendar, having been instituted in 1925 by Pope Pius XI for the Roman Catholic Church.  In 1970 its Roman Catholic observance was moved to the final Sunday of Ordinary Time.  Therefore, the earliest date on which it can occur is 20 November and the latest is 26 November.  Traditional Catholics observe it on its original date, the last Sunday of October.  The Anglican, Lutheran, and many other Protestant churches adopted it along with the Revised Common Lectionary, occasionally referring to it as Christ the King Sunday.  It is also observed on the same computed date as the final Sunday of the ecclesiastical year, the Sunday before the First Sunday of Advent, by Western rite parishes of the Russian Orthodox Church Outside Russia.  Roman Catholics adhering to the Extraordinary Form of the Roman Rite as permitted under the motu proprio "Summorum Pontificum" use the General Roman Calendar of 1960, and as such continue to observe the Solemnity on its original date of the final Sunday of October.
  Title: Arg (Kabul)
  Passage: The Arg (Pashto: ارګ‎ ; Persian: ارگ‎ ‎ ; meaning "citadel") serves as the presidential palace in Kabul, Afghanistan.  It sits on an 83 acre site in the affluent neighbourhood of Wazir Akbar Khan.  The Arg was built after the destruction of the Bala Hissar in 1880 by the British Indian troops.  It has been used by many Afghan kings and presidents, from Emir Abdur Rahman Khan to current President Ashraf Ghani.
  Title: Viceroy's commissioned officer
  Passage: A viceroy's commissioned officer (VCO) was a senior Indian member of the British Indian Army.  VCOs were senior in rank to warrant officers in the British Army, and held a commission issued by the viceroy.  Also known as "Indian officers" or "native officers", they were treated in almost all respects as commissioned officers, but only had authority over Indian troops and were subordinate to all British King's (and Queen's) commissioned officers and King's commissioned Indian officers.
  Title: 2017 China–India border standoff
  Passage: The 2017 China India border standoff or Doklam standoff refers to the military border standoff between the Indian armed forces and the People's Liberation Army of China over construction of a road in Doklam, known as Donglang, or Donglang Caochang (meaning Donglang pasture or grazing field), in Chinese.  On 16 June 2017 Chinese troops with construction vehicles and road-building equipment began extending an existing road southward in Doklam, a territory which is claimed by both China as well as India's ally Bhutan.  On 18 June 2017, around 270 Indian troops, with weapons and two bulldozers, entered Doklam to stop the Chinese troops from constructing the road.  On 28 August, both India and China announced that they had withdrawn all their troops from the face-off site in Doklam.
