What is the capital city of Indiana?

The capital city of Indiana is Indianapolis. This city serves as the political and administrative center of the state, housing the Indiana Statehouse, where the state government operates. Indianapolis is also significant for its historical and cultural contributions, being home to various institutions, museums, and sports events.

Fort Wayne, Bloomington, and South Bend are notable cities in Indiana, each with their own unique attributes and importance, but they do not hold the status of the state's capital. Fort Wayne is known for its manufacturing and commerce, Bloomington is famous for Indiana University, and South Bend is known for the University of Notre Dame. However, none of these cities serve as the political hub of Indiana like Indianapolis does. This distinction makes Indianapolis the correct answer to the question about the capital city of the state.
