Bombay geographically belongs to Konkan. Konkani-speaking people are the original inhabitants of Konkan. Marathi-speaking people later outnumbered Konkani-speaking people.
Bombay was built by the British. It was capital of Bombay Presidency which stretched from North Kanara to Singh and included Aden. In English it was officially Bombay and in other languages had different names. Many institutes came up which had Bombay in their names. One of them is Bombay Scottish School. The children of a leader of a political party were studying in the school. After they shifted to another school the members of that party demonstrated against the school and wanted to change its name. They want to change the names of many other institutes.
Now also most people refer to it as Bombay while speaking in English. Even many Marathi speakers refer to the city as Bombay. One Marathi newspaper had reported that Vilasrao Deshmukh was not in favour of change of name. St. Petersburg became Petrograd, then Leningrad and then again St. Petersburg. It is time for people who like the name Bombay to demand that Bombay be officially Bombay once again.
