Sultan Muhammad Quli Qutub Shah,the 5th Qutub Shahi ruler built Charminar in 1591 shortly after he had shifted his capital from Golkonda to what now is known as Hyderabad. He built this famous structure to commemorate the elimination of a plague epidemic from this city. He is said to have prayed for the end of a plague that was ravaging his city and vowed to build a masjid at the very place where he was praying. The Mosque became popularly known as Charminar because of its four (Farsi and Urdu char = four) minarets (Minar (Arabic manara) = spire/tower), which was possibly was to honour the first four caliphs of Islam.
Before the advent of Hyderabad, Deccan was ruled from Golconda fort. It was earlier established by the Kakatiya's in the 13th century and the existing structure was constructed by the Qutub Shahi kings. It was renovated by the first three Qutub Shahi kings, over a span of 62 years.
Golconda is also known as Shepherd's Hill" or "Golla Konda", in Telugu. According to a legend, a shepherd boy found an idol on the rocky hill called 'Mangalavaram'. This news reached the Kakatiya king, who was then ruling Golconda.
