Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted.:viii A further consequence of this northsouth mix is that both Telugu and Urdu are official languages of Telangana. The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims.
What event pushed Hyderabad to the top of India's cultural centres?
the decline of the Mughal Empire

The KU men's basketball team has fielded a team every year since 1898. The Jayhawks are a perennial national contender currently coached by Bill Self. The team has won five national titles, including three NCAA tournament championships in 1952, 1988, and 2008. The basketball program is currently the second winningest program in college basketball history with an overall record of 2,070806 through the 201112 season. The team plays at Allen Fieldhouse. Perhaps its best recognized player was Wilt Chamberlain, who played in the 1950s. Kansas has counted among its coaches Dr. James Naismith (the inventor of basketball and only coach in Kansas history to have a losing record), Basketball Hall of Fame inductee Phog Allen ("the Father of basketball coaching"), Basketball Hall of Fame inductee Roy Williams of the University of North Carolina at Chapel Hill, and Basketball Hall of Fame inductee and former NBA Champion Detroit Pistons coach Larry Brown. In addition, legendary University of Kentucky coach and Basketball Hall of Fame inductee Adolph Rupp played for KU's 1922 and 1923 Helms National Championship teams, and NCAA Hall of Fame inductee and University of North Carolina Coach Dean Smith played for KU's 1952 NCAA Championship team. Both Rupp and Smith played under Phog Allen. Allen also coached Hall of Fame coaches Dutch Lonborg and Ralph Miller. Allen founded the National Association of Basketball Coaches (NABC), which started what is now the NCAA Tournament. The Tournament began in 1939 under the NABC and the next year was handed off to the newly formed NCAA.

155th Street starts on the West Side at Riverside Drive, crossing Broadway, Amsterdam Avenue and St. Nicholas Avenue. At St. Nicholas Place, the terrain drops off steeply, and 155th Street is carried on a 1,600-foot (490 m) long viaduct, a City Landmark constructed in 1893, that slopes down towards the Harlem River, continuing onto the Macombs Dam Bridge, crossing over (but not intersecting with) the Harlem River Drive. A separate, unconnected section of 155th Street runs under the viaduct, connecting Bradhurst Avenue and the Harlem River Drive.
