Humayun's tomb (Urdu: ہمایوں کا مقبرہ Humayun ka Maqbara) is the tomb of the Mughal Emperor Humayun. The tomb was commissioned by Humayun's wife Hamida Banu Begum in 1562 AD, and designed by Mirak Mirza Ghiyath, a Persian architect. It was the first garden-tomb on the Indian subcontinent, and is located in Nizamuddin East, Delhi, India, close to the Dina-panah citadel also known as Purana Qila (Old Fort), that Humayun founded in 1533. It was also the first structure to use red sandstone at such a scale The tomb was declared a UNESCO World Heritage Site in 1993, and since then has undergone extensive restoration work, which is still underway. Besides the main tomb enclosure of Humayun, several smaller monuments dot the pathway leading up to it, from the main entrance in the West, including one that even pre-dates the main tomb itself, by twenty years; it is the tomb complex of Isa Khan Niyazi, an Afghan noble in Sher Shah Suri's court of the Suri dynasty, who fought against the Mughals, constructed in 1547 CE.

Nasir ud-din Muhammad Humayun (Persian: نصیر الدین محمد همایون‎; full title: Al-Sultan al-'Azam wal Khaqan al-Mukarram, Jam-i-Sultanat-i-haqiqi wa Majazi, Sayyid al-Salatin, Abu'l Muzaffar Nasir ud-din Muhammad Humayun Padshah Ghazi, Zillu'llah; OS 7 March 1508 – OS 17 January 1556) was the second Mughal Emperor who ruled present day Afghanistan, Pakistan, and parts of northern India from 1530–1540 and again from 1555–1556. Like his father, Babur, he lost his kingdom early, but with Persian aid, he eventually regained an even larger one. On the eve of his death in 1556, the Mughal empire spanned almost one million square kilometers.

He succeeded his father in India in 1530, while his half-brother Kamran Mirza, who was to become a rather bitter rival, obtained the sovereignty of Kabul and Lahore, the more northern parts of their father's empire. He originally ascended the throne at the age of 22 and was somewhat inexperienced when he came to power.

Humayun lost Mughal territories to the Pashtun noble, Sher Shah Suri, and, with Persian aid, regained them 15 years later. Humayun's return from Persia, accompanied by a large retinue of Persian noblemen, signaled an important change in Mughal court culture, as the Central Asian origins of the dynasty were largely overshadowed by the influences of Persian art, architecture, language and literature and also there are many stone carved and Persian language In India from the time of Humayun also thousands of Persian manuscript in India.

Prince Karim, Aga Khan IV,NPk, NI, KBE, CC, GCC, GCIH, GCM (born December 13, 1936; Aga Khan is also transliterated Aqa Khan and Agha Khan) is an international businessman, racehorse owner and breeder, as well as the 49th and current Imam of Nizari Ismailism — a minority denomination of Shia Islam with 5-15 million adherents (under 10% of the Shia population). He has held the position of Imam under the title of Aga Khan IV since July 11, 1957, when, at the age of 20, he succeeded his grandfather, Sultan Muhammad Shah Aga Khan, also known as Aga Khan III. The Aga Khans indicate that they are direct descendants of Prophet Muhammad through his cousin and son-in-law, Ali, considered the first Imam in Shia Islam, and his wife Fatima az-Zahra, the Prophet’s daughter from his first marriage. As the Imam of Nizari Ismailism, the Aga Khan IV is considered by his followers to be the proof or hujjah of God on earth as well as infallible and immune from sin (just as an Imam is viewed in most other denominations of Shia Islam). He is further considered by his followers to be the carrier of the eternal Noor of Allah ("Light of God" - a concept unique to certain denominations of Shia Islam). In 1986, the Aga Khan ordained the current Ismailia Constitution - an ecclesiastical decree affirming to Nizari Ismailis his "sole right to interpret the Quran and provide authoritative guidance on [all] matters of faith" and formalizing his sole discretion, power and authority for the governance of Nizari Ismaili jamats (places of worship) and institutions.
