Some context: Ban Ki-moon (; Hangul: bangimun; Hanja: Pan Ji Wen ; Korean pronunciation: [pan.gi.mun]; born 13 June 1944) is a South Korean diplomat who was the eighth Secretary-General of the United Nations from January 2007 to December 2016. Before becoming Secretary-General, Ban was a career diplomat in South Korea's Ministry of Foreign Affairs and in the United Nations. He entered diplomatic service the year he graduated from university, accepting his first post in New Delhi, India.
After graduating from university, Ban received the top score on Korea's foreign service exam. He joined the Ministry of Foreign Affairs in May 1970 and worked his way up the career ladder during the years of the Yusin Constitution. Ban's first overseas posting was to New Delhi, India, where he served as vice consul and impressed many of his superiors in the foreign ministry with his competence. Ban reportedly accepted a posting to India rather than the United States, because in India he would be able to save more money to send to his family. In 1974 he received his first posting to the United Nations, as First Secretary of the South Permanent Observer Mission (South Korea became a full UN member-state on 17 September 1991). After Park Chung-hee's 1979 assassination, Ban assumed the post of Director of the United Nations Division. In 1980 Ban became director of the United Nations' International Organizations and Treaties Bureau, headquartered in Seoul. He has been posted twice to the South Korean embassy in Washington, D.C. Between these two assignments he served as Director-General for American Affairs in 1990-92. In 1992, he became Vice Chairman of the South-North Joint Nuclear Control Commission, following the adoption by South and North Korea of the Joint Declaration of the Denuclearization of the Korean Peninsula. From 1993 to 1994 Ban was Korea's deputy ambassador to the United States. He was promoted to the position of Deputy Minister for Policy Planning and International Organizations in 1995 and then appointed National Security Advisor to the President in 1996. Ban's lengthy career overseas has been credited with helping him avoid South Korea's unforgiving political environment. Ban was appointed Ambassador to Austria and Slovenia in 1998, and a year later he was also elected as Chairman of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO PrepCom). During the negotiations, in what Ban considers the biggest blunder of his career, he included in a public letter a positive statement about the Anti-Ballistic Missile Treaty in 2001, not long after the United States had decided to abandon the treaty. To avoid anger from the United States, Ban was fired by President Kim Dae-jung, who also issued a public apology for Ban's statement. Ban was unemployed for the only time in his career and was expecting to receive an assignment to work in a remote and unimportant embassy. In 2001, during the 56th Session of the United Nations General Assembly, South Korea held the rotating presidency, and to Ban's surprise, he was selected to be the chief of staff to general assembly president Han Seung-soo. In 2003, incoming president Roh Moo-hyun selected Ban as one of his foreign policy advisors.
What year did that happen?
A: in May 1970

Some context: Mumtaz Mahal (Urdu: mumtz mHal ), ([mum'ta:z me'hel]; meaning "the Exalted One of the palace"; Arjumand Banu; 27 April 1593 - 17 June 1631) was Empress consort of the Mughal Empire from 19 January 1628 to 17 June 1631 as the chief consort of the Mughal emperor Shah Jahan. The UNESCO World Heritage Site Taj Mahal in Agra, often cited as one of the Wonders of the World, was commissioned to act as her final resting place. Mumtaz Mahal was born Arjumand Banu Begum in Agra to a family of Persian nobility.
Upon his accession to the throne in 1628, Shah Jahan designated Mumtaz as his chief empress with the title of 'Malika-i-Jahan' ("Queen of the World") and 'Malika-uz-Zamani' ("Queen of the Age"). Mumtaz's tenure as empress was brief (spanning a period of only three years due to her untimely death), nonetheless Shah Jahan bestowed her with luxuries that no other empress was given before her. For example, no other empress' residence was as decorated as Khas Mahal (part of Agra Fort), where Mumtaz lived with Shah Jahan. It was decorated with pure gold and precious stones and had rose water fountains of its own. Each wife of the Mughal emperor was given regular monthly allowance for her gastos (housekeeping or travelling expenses). The highest allowance on record is 10 lakh rupees per year given to Mumtaz Mahal under Shah Jahan. Shah Jahan consulted Mumtaz in both private matters and the affairs of the state and she served as his close confidante and trusted adviser. At her intercession, he forgave enemies or commuted death sentences. His trust in her was so great that he gave her the highest honour of the land -- his imperial seal, the Mehr Uzaz, which validated imperial decrees. Mumtaz was portrayed as having no aspirations to political power, in contrast to her aunt, Empress Nur Jahan, the chief consort of Emperor Jahangir, who had wielded considerable influence in the previous reign. A great influence on him, often intervening on behalf of the poor and destitute, she also enjoyed watching elephant and combat fights performed for the court. Mumtaz also patronized a number of poets, scholars and other talented persons. A noted Sanskrit poet, Vansidhara Mishra, was the Empress' favourite. On the recommendation of her principal lady-in-waiting, Sati-un-Nissa, Mumtaz Mahal provided pensions and donations to the daughters of poor scholars, theologians, and pious men. It was quite common for women of noble birth to commission architecture in the Mughal Empire, so Mumtaz devoted some time to a riverside garden in Agra, which is now known as Zahara Bagh. It is the only architectural foundation which can be connected to her patronage.
